DURAL SINUS THROMBOSIS IN A PATIENT OF ULCERATIVE COLITIS

Axial FLAIR MR images and MR venograms showing acute infarcts in left cerebellar / left occipital regions due to thrombosis involving left transverse, left sigmoid sinuses along with left IJV.

Case history: 55 years old female with a long history of ulcerative colitis presenting with venous infarction due to dural sinus thrombosis.

Cerebral sinus thrombosis is an uncommon complication of ulcerative colitis( UC) in approximately 7.5%patients. It is probably due to genetic predisposition in combination with hypercoagulable state during relapse of UC.
It often presents with headaches and focal/ diffuse neurological signs.
It is important to be aware of this condition as it is a serious complication of inflammatory bowel disease with the potential of being fatal.
