A 45-year old man with untreated diabetes mellitus (HbA1c 11.0%) was admitted with headache and left limb weakness. Findings of diffusion-weighted and FLAIR MR images of the brain were unremarkable. However, cortical vein dilation and occlusion of the upper sagittal sinus were visualized on T₂^＊ and magnetic resonance venography images, respectively. Perfusion CT revealed increased mean transit-time in the right frontal lobe. Cerebral venous thrombosis was diagnosed and treated with intravenous heparin. The neurological symptoms disappeared on post onset day (POD) 8. Contrast CT on POD 13 revealed sagittal sinus recanalization and he was discharged 10 days later. Perfusion CT helped to identify cerebral venous thrombosis that might have been associated with untreated diabetes mellitus.
