Fig. 1Endoscopic findings. Endoscopic findings show hyperemic and edematous mucosa, friability, and shallow ulcers from the sigmoid colon to the rectum.
Fig. 2Non-enhance brain CT findings. (A) The CT shows hyperattenuating thrombus in the superior sagittal sinus (black arrow) with hypoattenuating lesion suggesting infarction at the left parietal lobe (black arrowhead), (B) and right frontal lobe (white arrow), as well as hemorrhagic infarction in A B left basal ganglia (white arrowhead).
Fig. 3Brain MRI with venography. MRI with venography shows venous thrombosis in the superior sagittal sinus (A, B, D, arrows) and, the right transverse sinus (C, arrow).
Fig. 4Interventional angiography. Interventional angiogram shows partial occlusion of the superior sagittal sinus (A, arrowhead) and straight sinus (B, arrowhead) with asymmetrical filling of the left side of the deep vein (B, arrowhead) and both transverse sinuses (A, arrow) with collateral venous drainage via the posterior neck venous channel (B, arrow).
Fig. 5Endoscopic findings. Follow-up endoscopy shows endoscopic
remission of UC.
Fig. 6CT venogram. CT venogram shows a decreased extent of multiple filling defects in the superior sagittal sinus, straight sinus, transverse sinuses and sigmoid sinus. L, left; R, right.
