The incidence of traumatic @entity438 are rare. In review of literature, only six cases of @entity439 in posterior fossa are reported. The @entity1 , 15-year-old @entity1 , was admitted on Dec. 18th, 1979, presented with unconsciousness after a traffic accident. She was developed @entity1662 and @entity1269 with @entity4265 and @entity1415 . Skull film showed an @entity174 and a laminal fracture of the atlas. CT scan demonstrated traumatic subarachnoid, @entity548 and @entity5745 . After accident, she regained consciousness with conservative therapy, but she deteriorated on the 10th hospitalized day. On the 17th day, lumbar puncture and CT scan revealed recurrent subarachnoid and @entity548 . The @entity439 on the lateral medullary segment of the right posterior @entity5487 was obtained by cerebral angiogram on the 35th day. The configuration and size of the @entity439 was easily demonstrated by CT scans and cerebral angigrams. On the 43rd day, the clipping of the common trunk of the right posterior @entity5487 was employed. Her postoperative course was uneventful and she was discharged on the 97th day in @entity558 . This @entity439 was suggested to be induced by severe @entity542 with clinical ad operative findings. With the introduction of CT scan, CT scan is more available diagnostic modality than cerebral angiography in the follow up study with severe @entity542 . And in the absence of pathological CT scan findings, suspicion of traumatic @entity73 such as @entity439 should be paid. As the conservative management of traumatic @entity438 carries high mortality rate up to 30-50%, the prompt diagnosis and direct surgical intervention are recommended.
