ABSTRACT: Forty‐seven year old female, with a history of anorexia nervosa, was admitted to a medical stabilization unit (ACUTE) complaining of abdominal pain exacerbated by oral intake, associated with nausea, and relieved by emesis.
Admission body mass index was 10.6. Labs were notable for hepatitis and hypoglycemia. On her progressive oral refeeding plan, she suddenly developed severe abdominal pain. Computed tomography (CT) revealed gastric dilatation and superior mesenteric artery (SMA) syndrome. SMA syndrome is a rare complication of severe malnutrition resulting from compression of the duodenum between the aorta and the SMA. It is diagnosed by an upper gastrointestinal series or an abdominal CT.
Gastric dilatation, in turn, is a rare complication of SMA syndrome to be included in the differential diagnoses of abdominal pain in severely malnourished patients as it is potentially life‐threatening. The patient was switched to an oral liquid diet, began weight restoring, and had resolution of symptoms.
