The Luxated Eddies-Ectopic Meningioma

Abstract

Meningioma is a commonly discerned, benign neoplasm of the central nervous system originating from cellular elements of meninges, particularly the arachnoid villous structures and meningothelial cells. The neoplasm is uncommonly delineated within extracranial or ectopic sites. Thus, ectopic meningioma infrequently emerges within extracranial or extra-osseous region of the head and neck or maxilla and mandible and may manifest as a cystoid lesion [1]. Meningioma is appropriately established with ultrastructural examination and cogent immunohistochemistry. The morphology and immunohistochemistry of ectopic meningioma is identical to the frequently discerned intracranial meningioma. Appropriate discernment of an extracranial meningioma is challenging, and misinterpretation may incur an inadequate clinical and surgical management, especially for tumours situated within the facial region.
