“…The ratio of male‐to‐female incidence is 40:35, and the age distribution ranges from 2 to 84 years in previous reports with detailed data. To date 110 cases of RM in 40 articles have been reported . The most common locations were convexity (25 of 74), anterior or middle cranial fossa (10 of 74), posterior cranial fossa (13 of 74) and falx or parasagittal sinus (16 of 74).…”

Meningiomas are the most common primary intracranial tumors. They are usually benign and slowly growing; however, they may show histologically malignant features categorizing them into grade II or III of World Health Organization (WHO) classification. Rhabdoid meningioma (RM) is an uncommon meningioma variant categorized as WHO grade III. The clinical course of RM is determined by local recurrences, invasion of adjacent brain and/or dura, widespread leptomeningeal dissemination, remote metastases and fatal clinical outcome. Herein we report a case with recurrent aggressive left occipital parasagittal region RM in which the patient initially declined radiation treatment. The tumor was resected four times in 5 years. Histopathological examination revealed a rhabdoid meningioma with metaplastic, papillary and chordoid differentiation. Six months after her fourth operation the patient died of progressive disease. RM is a rare subtype of malignant meningioma and the role of different adjuvant therapeutic options are still unknown. Clinical presentation, radiological features and pathologic findings of this uncommon tumor are discussed.

“…These tumors probably arise from the arachnoid cap cells in the arachnoid and pia of the sylvian fissure and enter the surface of the brain or along the Virchow–Robin spaces along the branches of the middle cerebral artery. It has also been speculated that the arachnoid cells rest during the migration process leading to development of meningiomas 7,8 . Intra‐parenchymal meningiomas more commonly occur in the pediatric age group whereas the Sylvian meningiomas more commonly occur in adults 4 .…”

Key Clinical MessageMeningiomas are slow‐growing tumors that develop from the arachnoid cap cells' meningothelial cells. Males are more likely to develop intra‐parenchymal meningiomas, which also manifest earlier than ordinary meningiomas and are uncommon.AbstractMeningiomas are slow‐growing neoplasms which arise from the meningothelial cells of the arachnoid cap cells. Unlike other meningiomas, intra‐parenchymal meningiomas do not originate from dura. Intra‐parenchymal meningiomas are more common in males and develop earlier than regular meningiomas. Because of the rare occurrence the intra‐parenchymal meningiomas, they are commonly misdiagnosed.

“…To the best of our knowledge, 50 cases of RM, including three case series, have been published in the English-language literature. 2,3,[8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] Rhabdoid features usually emerge as a focal change, in either benign or malignant meningiomas of other histological subtypes. 2,3 Pure variants of such tumors are very uncommon, but rhabdoid components tend to be more prominent in recurrent tumors.…”
