Vasculitis of the mesenteric vessels is considered rare and typically occurs as a part of systemic inflammation. Isolated mesenteric artery vasculitis without systemic involvement is rarely reported in the literature. Clinical presentation is usually nonspecific which can range from abdominal pain, nausea and vomiting to gangrene and intestinal perforation in severe cases. Recognizing mesenteric artery vasculitis as a potential cause of abdominal pain can be challenging, and delay in diagnosis can lead to significant mortality and morbidity. Herein, we present a case of a 19-year-old male who initially presented with abdominal pain. Later, isolated superior mesenteric artery (SMA) vasculitis was confirmed by CT angiography. Treatment with systemic steroids alone resulted in a marked improvement in the patient's symptoms as well as in radiographic findings.
Keywords: abdominal pain; inflammation; intestinal ischemia; superior mesenteric artery; vasculitis.
