[Cerebral infarction in Crohn's disease].

Thromboembolic complications in Crohn's disease are not rare. Most of them are disseminated vascular thrombosis or pulmonary emboli. Cerebral artery thrombosis is a rare complication of Crohn's disease. We describe a 27-year-old woman who had Crohn's disease for 8 years, with exacerbation 3 months before admission. She had bloody diarrhea, abdominal pain, weight loss, weakness, and anemia. Hemoglobin was 6.3 g/dl and she received 3 packed cell transfusions the day of admission. Her hemoglobin level rose to 13 g/dl. 2 days after admission she had generalized tonic-clonic convulsions, followed by hemiparesis. EEG and CT examinations showed right temporal lobe infarction. Many studies report a hypercoagulable state in Crohn's disease, which results in a thromboembolic tendency that is potentially fatal.
