A case of acute subdural hematoma of the posterior fossa is reported with special reference to the mechanism of bleeding and the CT findings. A 33-year-old male patient was admitted to our clinic under the loss of consciousness for about 18 hours after head injury. Lacerated wounds were observed at left frontal and right ear and retromastoid. Subcutaneous hematoma was palpated at left retromastoid region. The level of consciousness was 200 by Japan Coma Scale and 5 by Glasgow Coma Scale. Pupils were miotic and isocoric and, remained responsible to light. There was no fracture on plain skull X-P. CT scan revealed a high density area of 5×4×3cm in size at left posterior fossa except for the posterior surface of cerebellum. Subarachnoid hemorrhage was seen at basal cistern. Cisterns such as prepontine, ambient and quadrigeminal, as well as the fourth ventricle collapsed. Retrograde vertebral angiogram showed anterior displacement of the basilar and posterior inferior cerebellar arteries, but there was no other vascular anomaly. Suboccipital craniectomy was performed. No fracture of occipital bone was identified but subdural hematoma was found mainly between superior surface of cerebellum and tentorium. The hematoma was removed totally, and ruptured bridging vein attached to the tentorium was disclosed. The mechanism of bleeding is considered on rotation of brain or the shear strain between superior surface of cerebellum and tentorium to cause the bridging vein torn.
