Abstract:
Authors report five cases of chronic subdural hematoma that showed a specific sedimentation sign on computerized tomography(CT) as a clear interface dividing the hematoma into two parts:an upper hypodense and a lower hyperdense zone. All patients had definite history of head trauma more than 1 month before they developed acute disturbance of consciousness and pronounced hemiparesis. We had analyzed the clinical importance of this sedimentation level and reviewed the available literature. This finding was considered as a specific CT sign indicating a significant amount of recent hemorrhage within the subdural hematoma that was sufficiently old to result in its contents being homogenous prior to rebleed and clinically manifested by acute deterioration.
