Abstract A very unusual case of metastatic spread of a meningioma is described. The clinical presentation was of extradural spinal cord compression, without evidence of a primary tumor. Computed tomography did not reveal any intracranial meningioma; the histopathology of the extradural spinal tumor was identical with that of two ...

Intracanalicular meningiomas are extremely rare and difficult to differentiate from intracanalicular vestibular schwannomas. We report an unusual case of a posterior fossa meningioma in the proximal internal auditory canal that was originally diagnosed as a vestibular schwannoma due to its appearance on magnetic resonance imaging.

Chordoid meningioma: Rare variant of meningioma
Neuropathology, 2004Chordoid meningioma is a rare variant of meningioma that bears a striking histological resemblance to chordoma and has greater likelihood of recurrence. Although most meningiomas occur in the intracranial, orbital and intravertebral cavities, rare meningiomas have been reported in extracranial organs; thus, it is important to be able to distinguish ...

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.

Current Treatment Options in Neurology, 2010
Meningiomas are extra-axial dural-based tumors. They are the most common intracranial tumors, occur in mid to late life, and have a female predilection. Symptoms are a function of location. Meningiomas are usually benign, but atypical and malignant forms exist. Treatment is indicated for symptomatic lesions or when neurologic symptoms may shortly occur.

The American Journal of Surgical Pathology, 1986
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.

Brain Tumor Pathology, 2012
A 55-year old female was referred to the Department of Neurosurgery, Kitasato Hospital, because of a hearing impairment. Neuroimaging revealed a typical meningioma attached to the falx in the right frontal region. During surgery, an encapsulated, circumscribed, reddish-gray, slightly hard tumor attached to the falx was completely removed by an ...

Annals of Otology, Rhinology & Laryngology, 1979
A patient is presented with findings of separate intracranial and extracranial meningiomas, each of a different histologic type. A calcified fibrous meningioma, with secondary psammomatous features, presented as a left neck mass associated with hoarseness, dysphagia, a unilateral facial weakness and hearing loss.
