Subdural hematoma caused by cerebral tumors.

Three cases of subdural hematoma caused by intracranial tumors are presented. In one case sudden worsening of patient's condition was due to intracerebral and subdural hemorrhage. In the other one tumor manifested by intracranial hemorrhage and the patient was initially diagnosed as SAH. In this case only the capsule of hematoma was found during operation; spontaneous resolution of hematoma took place. In the third case tumor and hematoma were localized in posterior fossa. Two weeks before admission to the hospital the patient develops symptoms of mild intracranial hypertension, probably due to the growth in space occupying lesion volume, which was caused by the origin of hematoma. In all cases tumors were highly vascularized and showed tendency to bleeding. There was no history of trauma in any case.
