She had multiple previous admissions for similar episodes of abdominal pain since she was 15 years old. These episodes were less severe and resolved spontaneously without a diagnosis. Her medical and social histories were unremarkable. Vital signs on admission were within reference ranges, and her abdominal examination showed diffuse tenderness but no peritonitis. A plain abdominal radiograph (Figure 1) and a single-contrast barium enema radiograph (Figure 2) are shown.
