Current Opinion in Neurology, 1993
Meningiomas more often behave as benign tumors although their very rate of recurrence is unknown. These neoplasms have been exhaustively studied but neither their subtypes nor their histologic features were ever considered as reliable data of their biologic behavior.

Six meningiomas with abundant hyaline inclusions (pseudopsammoma bodies) were studied. As seen by light and electron microscopy, hyaline inclusions are composed of material of varying structures located in intracellular lumina lined by microvilli. A remarkable pericytic proliferation within the vessel walls was found in five cases.

The question of whether meningeal hemangiopericytoma is a variant of meningioma ("angioblastic meningioma") or a nosologically distinct entity remains controversial. We present the case histories of an intracranial meningioma and of a meningeal hemangiopericytoma, both of which developed extracranial metastases.

Neurosurgery, 1995
We report our experience with and long-term results of 37 patients with tentorial meningiomas who underwent surgery between 1972 and 1993. The average age was 43 years, and the mean duration of symptoms was 36 months. Headache (83.8%) and extremity or gait ataxia (35.1%) were the most common complaints.

Information on the vascular supply to meningiomas is critical to the neurosurgeon. Most meningiomas are supplied by the external carotid artery, though many get pial contribution as well. Angiogenesis is critical for these neoplasms to grow. Vascular endothelial growth factor (VEGF) has been a popular target of research to decrease angiogenesis ...

A 63-year-old woman underwent a left craniotomy for the removal of a middle cranial fossa meningioma. Microscopically, the tumor showed a transitional and fibroblastic histological pattern. Within the tumoral tissue there were collagenous foci where little eosinophilic masses were found.

Meningiomas are the most common primary CNS tumor in adults, representing a third of brain lesions. Their clinical presentation varies greatly, ranging from asymptomatic incidental tumor to fatal tumor. The majority of meningiomas are benign, and gross total resection can achieve very low recurrence rates, with radiation therapy or radiosurgery ...

Interstitial intracranial radiotherapy implants, or brachytherapy, is an adjuvant option for treatment of recurrent high-grade meningiomas after resection. The implants are placed in the resection cavity following tumor resection. The most commonly used isotope is Iodine-125 (I-125).
