Meningioma

A rare, mostly benign, primary tumor of the meninges (arachnoid cap cells), usually located in the supratentorial compartment, commonly appearing in the sixth and seventh decade of life, clinically silent in most cases or causing hyperostosis close to the tumor and resulting in focal bulging and localized pain in less than 10% of cases. Additional features may include headache, seizures, gradual personality changes (apathy and dementia), anosmia, impaired vision, exophthalmos, hearing loss, ataxia, dysmetria, hypotonia, nystagmus, and rarely spontaneous bleeding.

Neurosurg Rev. 2017;40(1):163-169.
Clinical and radiological features or characteristics of posterior clinoid process (PCP) meningiomas have rarely been described because of their extreme scarcity and terminological confusion.

"Benign" metastatic meningioma: clinico-pathological analysis of one case metastasising to the lung and overview on the concepts of either primitive or metastatic meningiomas of the lung.
Asioli S, Senetta R, Maldi E, D'Ambrosio E, Satolli MA, Bussolati G, Cassoni P.
Virchows Arch. 2007;450(5):591-4.
Lung metastatic meningiomas may be a diagnostic challenge because of their unusual site of presentation and the possible confusion with primitive lung meningiomas or primary mesenchymal lung lesions.

Brain Tumor Pathol. 2006;23(1):65-70.
The primary intracranial giant cell type of malignant fibrous histiocytoma (GC-MFH) is rare, and the resemblance to meningioma causes diagnostic confusion.

Metastatic dermatofibrosarcoma protuberans mimicking meningioma.
Auer IA, Auer RN.
Clin Neuropathol. 1998;17(4):190-3.
The dural-based location of the intracranial metastasis, together with the light- and electron-microscopic appearance, could cause diagnostic confusion with an anaplastic syncytial meningioma.

Ultrastruct Pathol. 1990;14(4):367-74.
This rare form of meningioma is a potential source of confusion with other myxoid neoplasms such as metastatic adenocarcinoma or chordoma.

In the case of a solitary lymphoma, the computed tomographic appearance is sometimes similar to that of a meningioma whereas, in multifocal disease, confusion with metastases is almost invariable.
