Cerebral venous sinus thrombosis is a rare complication of IBD that can be associated with high morbidity and mortality. This report is of a case of cerebral venous sinus thrombosis presenting in a young man during a relapse of ulcerative colitis (UC). CASE REPORT: A 27-year-old man presented with seizures and focal neurological deficit during a relapse of chronic UC. He was found to have left cerebral venous sinus thrombosis complicated by left frontotemporal infarction that was treated with anticoagulation therapy. CONCLUSIONS: Thromboembolic events are well documented extra-intestinal manifestation of IBD. Cerebral venous sinus thrombosis is a rare but serious complication that can be fatal. The correct diagnosis and timely management require a high degree of suspicion in patients with IBD who present with a new-onset headache, focal neurological symptoms, seizure, or altered mental status.
