title: [A case of small meningioma with acute subdural hematoma].
abstract: A 46-year-old female was transported to our clinic 4 hours after the onset of sudden headache and transient loss of consciousness. On admission, she was drowsy with slight left hemiparesis and anisocoria (left greater than right). The CT scan revealed a right subdural neurological deficit one month after the operation. the operation, we found that the hematoma was derived from a small meningioma attached to the dura at the middle temporal fossa. The meningioma was 1.5 cm in diameter. The patient was discharged without neurological deficit one month after the operation. Although glioblastoma and metastatic brain tumor are most common, meningioma is rare as a cause of intracranial bleeding. Among 69 cases of meningioma with intracranial bleeding reported previously, only 4 cases were accompanied with acute subdural hematoma.
