 A 41-year-old healthy man presented with sudden disturbance of consciousness and convulsion during a marathon. Computed tomography revealed a lateral sinus sign in the posterior fossa, and magnetic resonance(MR)venography revealed a flow gap in the posterior part of the superior sagittal sinus and bilateral transverse sinus, although the other MR image sequences were normal. Laboratory data revealed dehydration, acute kidney failure, and rhabdomyolysis. Owing to immediate correction of dehydration, clinical symptoms and radiological abnormality improved rapidly.

 Cerebral venous sinus thrombosis(CVST)is a rare condition, accounting for <1% of all stroke cases. In all cases, CVST cannot cause cerebral infarction or hemorrhagic change but in any case, may present a transient ischemic attack-like event because of rapid spontaneous recanalization. Therefore, CVST may occur more frequently than expected.
