Adult tentorial medulloblastoma mimicking meningioma: A case report and systematic review.

Background: Tentorial medulloblastomas in adults are exceedingly rare and may clinically and radiologically mimic meningiomas. This case report, with a systematic review, aims to outline the clinical, radiological, pathological, and management strategies for adult tentorial medulloblastoma.

Case description: A 37-year-old male patient presented with headaches, vertigo, and vomiting. Imaging investigations revealed a tentorial extra-axial mass, initially considered a meningioma. The patient subsequently underwent surgical resection followed by chemoradiation. Histopathological examination ultimately identified the mass as an eccentrically located adult medulloblastoma. We conducted a systematic review of the literature, analyzing four studies that reported similar cases. This analysis included clinical and demographic information, diagnosis through imaging and histopathology, treatment methods, and outcomes for seven cases, including our own.

Conclusion: Adult tentorial medulloblastomas are extremely rare tumors that may mimic meningiomas, posing significant clinical challenges. Accurate diagnosis necessitates advanced imaging techniques and histopathological confirmation. The primary treatment strategy involves maximal surgical resection, supplemented by chemoradiotherapy.
