Cerebral venous sinus thrombosis (CVST) is a rare condition affecting mountaineers in high altitude areas. We present a case of a 45-year-old male who presented with headache, nausea, and visual impairment immediately after the descent from K-2 mountain (8611 meters) in Pakistan. His neurological exam did not reveal any findings, CT scan brain was done which showed thrombosis in the superior sagittal sinus with associated wedge-shaped hemorrhage in the frontal lobe. He was managed conservatively on anticoagulation and was discharged subsequently.
