베체트병을 진단 받았거나, 의심되는 환자에서 왼쪽 옆구리통증이 동반될 경우, 혈전성 혈관염에 동반된 비장 경색을 감별해야 하겠다.

Behcet`s disease is a multisystem autoimmune disease with vasculitic features, and major vascular involvement occurs in 7.7-60% of patients. Venous lesions are more common than arterial lesions and arterial thrombotic events are relatively rare. Wereport a patient with Behcet`s disease who developed a splenic infarct associated with splenic thrombotic arteritis. A 44-year-oldman who had been diagnosed with Behcet`s disease 5 years earlier presented with left flank pain lasting for 5 days. Laboratory tests revealed an elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). Computed tomography (CT) and three-dimensional CT showed a wedge-shaped splenic infarct and thrombus in the splenic artery. We treated him with low-molecular-weight heparin and prednisolone. The symptoms improved within 6 days of hospitalization, after which we stopped the heparin and added methotrexate and azathioprine. Splenic infarct should be ruled out if patients with Behcet`s disease complain of new left-sided abdominal pain. (Korean J Med 2011;81:126-129
