Delayed traumatic intracerebral hematomas after surgical decompression

Abstract

Delayed traumatic intracerebral hematomas found after an initially unrevealing computerized tomographic scan have been reported occasionally. Such hemorrhage may occur in an area of brain contusion with cerebral vessel injury. Four cases of intracerebral hematoma appearing after evacuation of a different traumatic intracranial mass lesion are reported. This suggests that an intracranial mass lesion may tamponade cerebral venous oozing in an area of brain contusion and delay the accumulation of intracerebral blood, accounting for the late discovery of a parenchymal hematoma.
