Acute Subdural Hematoma with Rapid Resolusion : Report of Three Cases

Abstract

The authors report 3 cases of traumatic acute subdural hematoma. Two of the three hematomas, showing mixed density on computed tomography, were rapidly resolved, but one of the three hematomas was not resolved. Two mechanisms of rapid resolution of acute subdural hematoma were thought to be : 1)obliteration by the pressure produced by acute brain swelling, and ; 2)participation of the cerebrospinal fluid leakage secondary to tearing of the arachnoid membrane, which may have played an important role in washing out the hematoma.
