title: [Meningioma associated with acute subdural hematoma: a case report].
abstract: We present a case of meningioma associated with acute subdural hematoma. This 67-year-old male had a sudden onset of severe headache when he was on the train. He had a CT scan which revealed an acute subdural hematoma at the left parietal convex. Cerebral angiography disclosed a small focus (3 x 4 cm) of vascular stain under the left parietal bone supplied by the left middle meningeal artery. He was diagnosed as having a meningioma with surrounding acute subdural hematoma. The removal of this tumor was carried out without delay. It was fragile and the bleeding point was not detected. Pathological diagnosis was meningothelial meningioma. The literature showed meningioma associated with acute subdural hematoma is rare, but when it is discovered incidentally, surgical resection might be indicated.
