We report a rare case of traumatic spinal subarachnoid @entity1410 with @entity4889 following @entity130 . A 43-year-old @entity1 was admitted to our hospital four days after @entity130 complaining of @entity158 , left @entity1269 and dysesthesia of the left arm. On the third hospital day, neurological examination revealed left C2,3 level @entity4889 . High cervical plain CT scan showed a high density area in the left spinal canal from C1 vertebral body level to C2-3 intervertebral level. Emergency operation was performed and a left-sided subarachnoid @entity1410 was removed. The left C2 and C3 nerve roots were markedly stretched and the cord was shifted to the right. Neither @entity455 nor @entity5 was found and no traumatic change was seen on the cord. The @entity4889 disappeared soon after surgery, but the weakness of the left arm and anesthesia at the level of left C2 dermatome remained until six months after operation. Review of the literature revealed no such a case as the one in which the @entity1 developed a spinal subarachnoid @entity1410 following @entity130 without any preexisting @entity66 of the spine. @entity4889 caused by spinal subarachnoid @entity1410 was not found on the literature either. So we believe that this is the first report of case of such lesion. The mechanism of @entity510 formation on @entity130 may be due to transient dislocation of the spine with tearing of the anterior longitudinal ligament or to crushing of the cord between the ligamentum flavum, which bulged forward on hyperextension, and the posterior aspect of the vertebral body.(ABSTRACT TRUNCATED AT 250 WORDS)
