title: Cerebral venous thrombosis due to high-altitude polycythemia. Case report.
abstract: A case of cerebral venous thrombosis due to polycythemia secondary to adaptation to a high altitude is reported. A 27-year-old previously healthy man developed severe neurological symptoms after climbing 8511 m. Computerized tomography and cerebral angiography suggested hemorrhagic infarction or intratumoral hemorrhage, and a craniotomy was performed. Pathological examination confirmed the diagnosis of hemorrhagic infarction secondary to cortical venous thrombosis. The etiology and incidence of cerebral venous thrombosis secondary to polycythemia are discussed.
