FALX MENGIOMA: CASE REPORT AND REVIEW

Abstract

ABSTRACT

Meningiomas are tumors of the central nervous system that originate in the meninges and spinal cord. It is a benign, slow-growing neoplasm thought to originate from meningothelial cells. Meningiomas are typically oval lesions attached to the dura mater. They are most commonly located supratentorial to the calvaria or at the base of the meninges. Meningiomas can also be found in the tentorium, intraventricularly, or in the cerebellopontine region. Meningiomas arise from meningothelial cap cells that are normally distributed throughout the arachnoid trabeculation. The highest concentration of meningothelial cells is found in the arachnoid villi of the dural sinuses, cranial nerve foramina, middle cranial fossa, and cribriform plate. Additionally, meningiomas are commonly found over the convexity, along the falx, and at the base of the skull.
