Died on July 9, 2014, from complications of meningioma and osteoporosis. [49] Mary Tyler Moore (1936–2017), American actress, underwent surgery in May 2011 to remove a benign meningioma.
Cerebrospinal fluid shunt (CSF) associates with the risk of meningitis due to the following factors: pre-shunt associated infections, post-operative CSF leakage, lack of experience from the neurosurgeon, premature birth/young age, advanced age, shunt revisions for dysfunction, and neuroendoscopes.
Hemangiopericytoma is an aggressive mesenchymally derived tumor with oval nuclei with scant cytoplasm. There is dense intercellular reticulin staining. Tumor cells can be fibroblastic, myxoid, or pericytic. These tumors, in contrast to meningiomas, do not stain with epithelial membrane antigen.
Meningiomas have been divided into three types based on their patterns of growth. Histological factors that increase the grade include a high number of mitotic figures, necrosis and local invasion. Treatment of sphenoid wing meningiomas often depends on the location and size of the tumor.
Optic nerve sheath meningiomas (ONSM) are rare benign tumors of the optic nerve. 60–70% of cases occur in middle age females, and is more common in older adults (mean age 44.7 years). It is also seen in children, but this is rare.
The most common cerebellopontine angle (CPA) tumor is a vestibular schwannoma affecting cranial nerve VIII (80%), followed by meningioma (10%). The cranial nerves affected are (from most common to least common) : VIII (cochlear component), VIII (vestibular component), V. Acoustic neuroma / vestibular schwannoma.
Leptomeningeal cancer is a rare complication of cancer in which the disease spreads from the original tumor site to the meninges surrounding the brain and spinal cord. [1] This leads to an inflammatory response, hence the alternative names neoplastic meningitis (NM), malignant meningitis, or carcinomatous meningitis.
Postoperative complications include wound dehiscence, hydrocephalus, infection, and a substantial proportion of patients may also require tracheostomy and gastrotomy in the early phase after surgery. [38]
Patients with NF2 who have meningiomas have a higher risk of mortality, and the treatment can be very challenging. Individuals who develop schwannomas frequently develop hearing loss and deafness. These individuals may also develop tinnitus after being presented with unilateral hearing loss.
Malignant meningioma is a rare, fast-growing tumor that forms in one of the inner layers of the meninges (thin layers of tissue that cover and protect the brain and spinal cord). Malignant meningioma often spreads to other areas of the body.
