Types of Meningioma Brain Tumors After Receiving Depo-Provera Shots

Depo-Provera Meningioma Types

A meningioma is a tumor of the meninges, the protective membranes surrounding the brain and spinal cord. It is sometimes described as an arachnoid-related tumor because many meningiomas arise from arachnoid cap cells within those membranes.

Different types of meningiomas may be diagnosed after a patient receives Depo-Provera birth control shots. Meningiomas may be classified by grade, including Grade 1, Grade 2, or Grade 3 meningiomas, or by the location where the brain tumor develops, such as convexity meningiomas (surface of brain), parasagittal (near sagittal sinus vein), falcine (near falx cerebri membrane that separates two halves of brain), skull base (bottom of skull), sphenoid wing (near sphenoid bone behind eyes), olfactory groove (near nerves responsible for smell), cerebellopontine angle (where cerebellum, brainstem, and cranial nerves meet), spinal meningioma (spinal cord membranes) or suprasellar meningioma (near pituitary gland and optic chiasm).

Meningiomas may also sometimes be classified by histological subtype, which refers to the specific cell pattern and tissue features seen under a microscope, such as meningothelial, fibrous, transitional, angiomatous, chordoid, clear cell, papillary, rhabdoid, or anaplastic meningioma.

This page explains the different types of meningiomas and how they may be relevant to a Depo-Provera meningioma lawsuit. In a Depo-Provera meningioma lawsuit, the specific type of meningioma may be important because different tumors can involve different levels of harm. Some meningiomas may only require monitoring, while others may require brain surgery, radiation, repeat imaging, rehabilitation, or long-term neurological care. The tumor’s grade or location may also affect the amount of medical expenses, time missed from work, pain and suffering, and other damages that may be pursued in a legal claim.

If you (or a loved one) have suffered from meningioma after receiving Depo-Provera or Depo-SubQ Provera birth control injections, you may be eligible to recover compensation from a Depo-Provera meningioma lawsuit case or settlement claim.

Depo-Provera Meningioma Types: Overview

Main Types of Meningiomas

The main types of meningiomas are generally classified by tumor grade and tumor location. Tumor grade describes how aggressive the meningioma may be, ranging from Grade 1 tumors that are usually slower-growing to Grade 2 and Grade 3 tumors that may have a higher risk of recurrence or require more intensive treatment. Tumor location describes where the meningioma develops, such as on the surface of the brain, near the skull base, along the falx, near major blood vessels, around the optic nerves, or near the spinal cord.

Meningiomas are also sometime classified by histological sub-types (what their cells and tissues look like under a microscope) such as meningothelial, fibrous, transitional, angiomatous, chordoid, clear cell, papillary, rhabdoid, or anaplastic meningiomas.

In a Depo-Provera meningioma lawsuit, both the grade and location may be important because they can affect symptoms, treatment options, recovery time, future medical care, lost income, and the overall damages associated with the claim.

Meningioma Brain Tumor Grades

Meningiomas are commonly classified by grade, which describes how the tumor cells look under a microscope and how aggressive the tumor may be. The grade of a meningioma can affect how quickly the tumor may grow, whether it is likely to return after treatment, and what type of meningioma treatment after Depo-Provera use may be needed.

In a Depo-Provera meningioma lawsuit, tumor grade may be important because a higher-grade meningioma may require more aggressive meningioma treatment after Depo-Provera use (including surgery, radiation, repeat imaging and long-term follow-up care) and may involve greater recurrence risk, higher medical expenses, more time away from work, and greater damages.

Meningioma types by tumor grade include:

Meningioma grades are defined by the World Health Organization’s classification system for central nervous system tumors.

Grade 1 Meningioma

A Grade 1 meningioma is the most common and least aggressive type of meningioma. These tumors are often described as benign and tend to grow slowly. However, a Grade 1 meningioma can still cause serious health problems if it grows large enough or develops near sensitive areas of the brain, skull base, optic nerves, spinal cord, or major blood vessels.

Treatment for a Grade 1 meningioma may involve monitoring with regular MRI scans, surgery to remove the tumor, or additional treatment if the tumor cannot be fully removed. In a Depo-Provera meningioma lawsuit, even a Grade 1 tumor may be relevant if it caused symptoms, required surgery, led to medical bills, resulted in missed work, or created long-term neurological concerns.

Grade 2 Meningioma

A Grade 2 meningioma, also known as an atypical meningioma, is more aggressive than a Grade 1 tumor. These tumors may grow faster and have a higher risk of coming back after treatment. Because of that recurrence risk, patients with Grade 2 meningiomas may need closer follow-up care, more frequent imaging, radiation therapy, or additional surgery.

In a Depo-Provera meningioma lawsuit, a Grade 2 meningioma may be especially important because it can involve more complex treatment and greater uncertainty about future health. The need for ongoing monitoring, additional procedures, radiation, time away from work, and future medical care may increase the damages associated with the claim.

Grade 3 Meningioma

A Grade 3 meningioma, also called an anaplastic or malignant meningioma, is the most aggressive type of meningioma. These tumors may grow quickly, invade nearby tissue, and have a higher chance of recurring after treatment. Grade 3 meningiomas often require aggressive medical care, which may include surgery, radiation therapy, repeat imaging, specialist visits, rehabilitation, and long-term neurological follow-up.

In a Depo-Provera meningioma lawsuit, a Grade 3 meningioma may support a more serious injury claim because it can involve substantial medical costs, lost income, reduced earning capacity, permanent symptoms, disability, emotional distress, and reduced quality of life. Because these tumors can create ongoing health risks, future medical expenses and long-term damages may be especially important.

Meningioma Brain Tumor Locations

Meningiomas may also be classified by where the tumor develops in or around the brain (intracranial meningiomas), skull base, or spinal cord. Tumor location is important because it can affect symptoms of meningioma after Depo-Provera shots, treatment options, surgical risks, recovery time, and long-term complications. A meningioma near the optic nerves may affect vision, while a meningioma near the spinal cord may cause weakness, numbness, or walking problems.

Meningioma types by tumor location include:

In a Depo-Provera meningioma lawsuit, the location of the tumor may be relevant because it can help show how the diagnosis affected the patient’s medical care, ability to work, daily activities, and overall damages.

Convexity Meningioma

A convexity meningioma develops on the surface of the brain, along the outer curve of the cerebral hemispheres. These tumors may not cause symptoms until they become large enough to press on nearby brain tissue.

Possible symptoms of a convexity meningioma may include headaches, seizures, weakness, numbness, personality changes, or problems with thinking and coordination.

In a Depo-Provera meningioma lawsuit, a convexity meningioma diagnosis may be important if it required surgery, caused seizures or neurological symptoms, resulted in missed work, or required ongoing MRI monitoring and follow-up care.

Parasagittal Meningioma

A parasagittal meningioma develops near the sagittal sinus, a major vein that helps drain blood from the brain. Because these tumors grow close to an important blood vessel, treatment may be more complex, especially if the tumor invades or presses against the sinus.

Parasagittal meningioma symptoms may include headaches, seizures, leg weakness, numbness, difficulty walking, or changes in mental function.

In a Depo Provera lawsuit, a parasagittal meningioma diagnosis may be relevant because surgical complexity, neurological symptoms, recovery time, and future treatment risks may affect damages.

Falcine Meningioma

A falcine meningioma forms along the falx cerebri, the membrane that separates the left and right sides of the brain. Depending on its size and exact location, a falcine meningioma may affect movement, sensation, personality, or cognitive function.

Possible symptoms of a falcine meningioma may include headaches, seizures, leg weakness, memory problems, or changes in behavior.

In a Depo-Provera meningioma claim, a falcine meningioma diagnosis may be important if it caused neurological problems, required surgery, or led to long-term monitoring or functional limitations.

Skull Base Meningioma

A skull base meningioma grows along the bottom of the skull, near critical nerves and blood vessels. These tumors can be more difficult to treat because they may develop near the optic nerves, cranial nerves, brainstem, or major arteries.

Symptoms of a skull base meningioma may include vision problems, double vision, hearing loss, facial numbness, balance problems, headaches, or difficulty swallowing.

In a depo provera lawsuit, a skull base meningioma diagnosis may be especially significant because treatment can be more complex and may involve higher surgical risk, greater medical costs, longer recovery, and long-term neurological effects.

Sphenoid Wing Meningioma

A sphenoid wing meningioma develops near the sphenoid bone, which sits behind the eyes and forms part of the skull base. These tumors may affect vision, eye movement, facial sensation, or nearby brain structures.

Possible symptoms of a sphenoid wing meningioma may include vision loss, double vision, bulging of the eye, facial numbness, headaches, or seizures.

In a Depo-Provera meningioma lawsuit, a sphenoid wing meningioma diagnosis may be relevant because vision problems, eye-related complications, and complex surgery may increase medical expenses, lost income, pain and suffering, and long-term damages.

Olfactory Groove Meningioma

An olfactory groove meningioma grows near the olfactory nerves, which are responsible for the sense of smell. These tumors may become large before diagnosis because early symptoms, such as reduced smell, can be subtle or overlooked.

Symptoms of olfactory groove meningioma may include loss of smell, headaches, personality changes, memory problems, vision problems, or seizures.

In a Depo Provera brain tumor lawsuit, an olfactory groove meningioma diagnosis may matter because cognitive changes, personality changes, loss of smell, or vision problems may interfere with work, relationships, independence, and quality of life.

Cerebellopontine Angle Meningioma

A cerebellopontine angle meningioma develops near the area where the cerebellum, brainstem, and cranial nerves meet. This location may affect hearing, balance, facial movement, swallowing, and coordination.

Possible symptoms of a cerebellopontine angle meningioma may include hearing loss, ringing in the ears, dizziness, balance problems, facial numbness, facial weakness, headaches, or difficulty swallowing.

In a Depo-Provera meningioma lawsuit case, this type of tumor diagnosis may be important because it can cause functional limitations that affect driving, walking, working, communication, and daily independence.

Spinal Meningioma

A spinal meningioma develops in the membranes surrounding the spinal cord. Although meningiomas are often discussed as brain tumors, they can also occur along the spine and may compress the spinal cord or nerve roots.

Spinal meningioma symptoms may include back pain, numbness, tingling, weakness in the arms or legs, difficulty walking, balance problems, or bowel and bladder issues.

In a Depo-Provera meningioma lawsuit, a spinal meningioma diagnosis may be especially relevant if it caused mobility problems, required spinal surgery, led to rehabilitation, resulted in lost wages, or created long-term care needs.

Suprasellar Meningioma

A suprasellar meningioma develops in the suprasellar region, an area near the pituitary gland and the optic chiasm, where the optic nerves cross. Because of this location, suprasellar meningiomas may affect vision, hormone function, headaches, and nearby brain structures.

In a Depo-Provera meningioma lawsuit, a suprasellar meningioma diagnosis may be important because tumors in this area can involve vision loss, endocrine problems, complex surgery, long-term monitoring, missed work, and future medical care. These complications may affect the severity of the injury and the damages pursued in a legal claim.

Histological Subtypes of Meningiomas

Meningiomas may also be classified by histological subtype, which refers to the specific cell pattern and tissue features seen under a microscope.

While tumor grade and location are often the most important classifications for patients, histological subtype can provide additional information about how the tumor may behave, whether it is typically considered lower-grade or more aggressive, and what type of treatment or follow-up may be needed.

Meningioma histological subtypes include:

In a Depo-Provera meningioma lawsuit, histological subtype may be relevant if it helps show the seriousness of the diagnosis, the risk of recurrence, treatment complexity, long-term medical needs, or damages.

Meningothelial Meningioma

A meningothelial meningioma is one of the most common histological subtypes of meningioma. It is usually classified as a WHO Grade 1 meningioma, meaning it is generally considered lower-grade and slower-growing. However, it can still cause serious symptoms if it grows large or develops near sensitive areas of the brain, skull base, nerves, or spinal cord.

In a Depo-Provera meningioma lawsuit, a meningothelial meningioma diagnosis may be relevant if it required surgery, caused neurological symptoms, led to ongoing monitoring, or resulted in medical expenses, missed work, or long-term complications.

Fibrous Meningioma

A fibrous meningioma, also called a fibroblastic meningioma, is a subtype made up of spindle-shaped tumor cells and fibrous tissue. It is usually classified as a WHO Grade 1 meningioma. Although often considered lower-grade, a fibrous meningioma can still become serious depending on its size and location.

In a Depo-Provera lawsuit, a fibrous meningioma diagnosis may be relevant if it caused symptoms, required brain or spinal surgery, resulted in follow-up imaging, or affected the patient’s ability to work or perform daily activities.

Transitional Meningioma

A transitional meningioma has features of both meningothelial and fibrous meningiomas. It is generally considered a WHO Grade 1 meningioma and is often slower-growing. Like other Grade 1 tumors, it may still require treatment if it presses on the brain, spinal cord, optic nerves, or other important structures.

In a Depo-Provera meningioma claim, a transitional meningioma diagnosis may be relevant if it led to surgery, neurological symptoms, medical costs, lost income, or long-term monitoring.

Psammomatous Meningioma

A psammomatous meningioma is a subtype that contains many calcified structures called psammoma bodies. It is usually classified as a WHO Grade 1 meningioma. These tumors may be slow-growing, but they can still cause symptoms depending on where they develop.

In a lawsuit involving Depo-Provera and meningioma, a psammomatous meningioma diagnosis may be important if it caused headaches, seizures, nerve problems, spinal cord compression, surgery, or ongoing medical follow-up.

Angiomatous Meningioma

An angiomatous meningioma is a subtype that contains many blood vessels within the tumor tissue. It is typically classified as a WHO Grade 1 meningioma. Even though it is usually lower-grade, its vascular nature may be relevant to treatment planning, especially if surgery is required.

In a Depo-Provera meningioma lawsuit, an angiomatous meningioma diagnosis may be relevant if it required surgery, caused neurological symptoms, led to monitoring, increased medical expenses, or resulted in missed work or long-term health concerns.

Microcystic Meningioma

A microcystic meningioma is a subtype that contains small cyst-like spaces within the tumor tissue. It is generally classified as a WHO Grade 1 meningioma. These tumors are often lower-grade, but their symptoms and treatment needs depend on their size and location.

In a Depo-Provera claim, a microcystic meningioma diagnosis may matter if it caused brain swelling, neurological symptoms, surgery, follow-up imaging, or ongoing medical care.

Secretory Meningioma

A secretory meningioma is a less common subtype that may be associated with swelling around the tumor. It is usually classified as a WHO Grade 1 meningioma, but the swelling can sometimes contribute to symptoms such as headaches, seizures, or neurological problems.

In a Depo-Provera meningioma lawsuit, a secretory meningioma diagnosis may be relevant if swelling or tumor growth caused serious symptoms, required treatment, increased medical costs, or affected the patient’s ability to work or function normally.

Lymphoplasmacyte-Rich Meningioma

A lymphoplasmacyte-rich meningioma is a rare subtype that contains many inflammatory cells. It is generally classified as a WHO Grade 1 meningioma. Because it is uncommon, diagnosis may require careful pathology review.

In a lawsuit, this subtype may be relevant if it required specialist evaluation, surgery, monitoring, or treatment for symptoms caused by the tumor’s size, location, or surrounding inflammation.

Metaplastic Meningioma

A metaplastic meningioma is a rare subtype that contains tissue-like features not usually seen in ordinary meningiomas, such as bone, cartilage, fat, or other tissue patterns. It is usually classified as a WHO Grade 1 meningioma.

In a Depo-Provera meningioma claim, a metaplastic meningioma may matter if it caused symptoms, required surgery, led to unusual pathology findings, or created long-term medical needs.

Chordoid Meningioma

A chordoid meningioma is a more aggressive histological subtype that is generally classified as a WHO Grade 2 meningioma. Grade 2 meningiomas may have a higher risk of recurrence than Grade 1 tumors and may require closer monitoring or additional treatment.

In a Depo-Provera meningioma lawsuit, a chordoid meningioma may be especially relevant because it can involve greater recurrence risk, more intensive follow-up care, additional treatment, higher medical expenses, and greater future damages.

Clear Cell Meningioma

A clear cell meningioma is a rare subtype that is generally classified as a WHO Grade 2 meningioma. It may be more likely to recur than many Grade 1 tumors, making long-term follow-up especially important.

In a lawsuit involving Depo-Provera, a clear cell meningioma may be important because recurrence risk, repeat imaging, additional procedures, radiation therapy, lost wages, and long-term medical care may affect the value of the claim.

Atypical Meningioma

An atypical meningioma is a WHO Grade 2 meningioma that shows more aggressive features under a microscope. These tumors may grow faster and have a higher chance of returning after treatment compared to Grade 1 meningiomas.

In a Depo-Provera meningioma lawsuit, an atypical meningioma may support a more serious injury claim because it can involve more complex treatment, greater recurrence risk, additional monitoring, radiation, future medical expenses, and long-term neurological concerns.

Papillary Meningioma

A papillary meningioma is a rare and aggressive subtype that is generally classified as a WHO Grade 3 meningioma. Grade 3 meningiomas may grow more quickly, invade nearby tissue, and have a higher risk of recurrence.

In a Depo-Provera lawsuit, a papillary meningioma may be highly relevant because it can involve aggressive treatment, higher medical costs, lost income, disability, long-term follow-up, pain and suffering, and increased damages.

Rhabdoid Meningioma

A rhabdoid meningioma is another aggressive subtype generally classified as a WHO Grade 3 meningioma. These tumors may behave more aggressively than lower-grade meningiomas and may require surgery, radiation, and close long-term monitoring.

In a Depo-Provera meningioma lawsuit, a rhabdoid meningioma may be important because it can involve serious treatment, recurrence risk, neurological complications, substantial medical expenses, time away from work, and long-term health consequences.

Anaplastic Meningioma

An anaplastic meningioma, also called a malignant meningioma, is a WHO Grade 3 meningioma. It is one of the most aggressive types of meningioma and may grow quickly, invade nearby tissue, and return after treatment.

In a Depo-Provera meningioma lawsuit, an anaplastic meningioma may support significant damages because it can involve aggressive medical treatment, radiation therapy, repeat surgery, ongoing neurological care, lost earning capacity, permanent symptoms, emotional distress, and reduced quality of life.

Why Tumor Type Matters in a Depo-Provera Lawsuit

In a Depo Provera lawsuit, the type of meningioma may help show the severity of the injury. Different tumor types can involve very different medical outcomes. Some people may only need monitoring, while others may require brain surgery, radiation, repeat treatment, rehabilitation, or lifelong neurological follow-up.

The type of meningioma may affect:

  • The complexity of surgery
  • The risk of tumor recurrence
  • The need for radiation or additional treatment
  • The amount of past and future medical expenses
  • Time missed from work
  • Loss of earning capacity
  • Long-term neurological symptoms
  • Vision, hearing, balance, memory, or mobility problems
  • Pain, suffering, and emotional distress
  • Reduced quality of life
  • The overall value of a potential lawsuit

For example, a skull base meningioma near the optic nerve may cause vision problems and require complex surgery. A Grade 2 or Grade 3 meningioma may involve a greater risk of recurrence and more aggressive treatment. A spinal meningioma may affect walking, strength, or bladder function. These details can help attorneys understand how the tumor affected the person medically, financially, and personally.
