Pseudotumor Cerebri in a Case of Ulcerative Colitis with Sagittal Sinus Thrombosis

Background Thromboembolic events are a known complication of Inflammatory Bowel Disease (IBD) especially during disease relapse, more commonly in deep veins of extremities and lung, and rarely as Cerebral Sinovenous Thrombosis (CSVT). Case Presentation We describe an 11 year, old male patient with 3 months history of Ulcerative Colitis (UC) who presented as pseudotumor cerebri due to superior sagittal sinus thrombosis during an acute exacerbation of his colitis, that was successfully treated with heparin and then warfarin. Conclusion In any known cases of UC presenting as acute severe headache, consider CSVT and request brain MRI and MRV to facilitate the diagnosis and early treatment.
