A 27-year-old woman presented with an acute worsening of chronic epigastric pain, which had been present since normal, spontaneous, vaginal delivery of a healthy, full-term infant 1 month previously. In the 2 days prior to admission, the patient experienced nausea; 2 episodes of bilious emesis; and frequent, small, loose stools. Physical examination showed an afebrile, stable patient in moderate distress with significant epigastric tenderness and a palpable, transverse supraumbilical mass, which measured approximately 10 × 2 cm. Laboratory findings were unremarkable. Abdominal computed tomography was performed (Figure 1) and demonstrated a soft tissue lesion involving the ascending to mid transverse colon consistent with intussusception of the ileocecal region into the transverse colon. The patient underwent resection of the involved bowel (Figure 2). She had an uneventful recovery and was discharged on the fifth postoperative day.
