Rhabdoid meningioma is a rare subtype of meningiomas accounting for 1-3% of all intracranial meningiomas and classified as WHO Grade III tumor. It has an aggressive course and needs to be treated by both surgery and radiotherapy. Here we present a rare case of rhabdoid meningioma in a 24 year old lady with complaints of focal seizures, paresis and diplopia. CT & MRI showed a mass attached to dura in left posterosuperior frontoparietal region with peripheral edema. Histopathology showed large tumor cells arranged in sheets, whorls and papillary pattern. The patient was treated by surgery followed by radiation. This is reported to aware the surgical pathologists to keep this subtype as a differential diagnosis while interpreting any meningioma as it has an aggressive course.
