title: Acute subdural hematoma after aneurysmal rupture; evacuation with aneurysmal clipping after emergent infusion computed tomography: case report.
abstract: A 74-year-old woman sought treatment after an initial subarachnoid hemorrhage verified on computed tomographic scan with no focal neurological deficit. Shortly after admission, she sustained a second subarachnoid hemorrhage with acute neurological decompensation. A repeat computed tomographic scan revealed increased blood along the right medial temporal region, as well as in the interhemispheric fissure and bilateral sylvian cisterns. Also evident was a right hemispheric acute subdural hematoma. The patient's rapidly deteriorating neurological status precluded a cerebral angiogram; therefore, a double-dose infusion computed tomographic scan was performed. This revealed a cerebral artery aneurysm adjacent to the right medial temporal hematoma. She was taken to the operating room on the basis of this study. After evacuation of the right hemispheric subdural hematoma and clipping of the right posterior communicating artery aneurysm, the patient made a rapid, full neurological recovery.
