Cerebral Venous Thrombosis as an Initial Presentation of Ulcerative Colitis

Figure 1

(a) Sagittal and (b) coronal images of nonenhanced brain computed tomography (CT) showing a high-density area in the right frontoparietal lobe, consistent with right lobar intracranial hemorrhage (ICH). (c) A head magnetic resonance image (MRI) with fluid attenuation inversion recovery (FLAIR) showing infarction surrounding subcortical hemorrhage of the frontoparietal lobe. (d) Magnetic resonance venography (MRV) revealing an absence of normal flow patterns of the superior sagittal sinus (arrow). (e) Cerebral angiogram showing total occlusion of the right rolandic vein (dotted circle) and inferior sagittal sinus (arrow heads) and partial occlusion of the superior sagittal sinus (arrow) caused by thrombosis (Figure 1(c)).
