Subdural hematoma in patients with brain tumor: CT evaluation.

Chronic subdural hematoma was identified radiographically and verified surgically in two patients with brain tumor, one meningioma, and one glioblastoma multiforme. Over a period of days or weeks, both patients developed dramatic clinical findings probably related to the mass effect from the subdural hematoma in addition to the preexisting tumor. Early awareness of this complication in patients with brain tumor may lead to successful surgical treatment.
