Case report and literature review demonstrates a rare hemorrhagic vermian epidermoid cyst presenting with headache and ataxia, highlighting an unusual cause of posterior fossa bleeding.
Intracranial epidermoid cysts (ECs) are rare entities, constituting less than 2% of all brain tumors. While they are commonly found in the cerebellopontine angle, parasellar, and temporal regions, localization in the cerebellar vermis is extremely rare. We report a case of a hemorrhagic vermian EC in a 57-year-old patient who presented with headache and unsteady gait. This report also reviews similar cases documented in the English literature, marking our case as the eighth reported instance of a hemorrhagic vermian EC.
