Abstract

A clinical analysis of unusual sited traumatic subdural hematomas are presented and discussed. These disorders are rare form of intracranial hemorrhage. Commonly, acute subdural hematoma is located in the cerebral convexity, which shows a cresent-shaped increased density on axial Brain CT scan. A conventional axial CT scan is difficult to detect the tentorial subdural hematoma because of artifact of petrous pyramid. So coronal CT scan is prefered diagnostic procedure. This hematoma is originated from a bridging vein at the edge of a tetorial or falx-tentorial junctional tear. Interhemispheric subdural hematoma is originated from a bleeding of bridging vein between the superior saggital sinus and cerebral cortex. Conservative treatment for above hematoma may be beneficial unless neurological deterioration necessitates early operative procedure.
