Case Report: Idiopathic Postpartum Intussusception: A Rare Cause of Acute Abdominal Pain

Objectives: To present a case with acute abdominal pain due to idiopathic intestinal intussusception diagnosed by ultrasound and computed tomography (CT) during the early postpartum period. Clinical Presentation and Intervention: A 21-year-old female patient was admitted to our hospital with abdominal pain, nausea and emesis after a normal vaginal delivery. Laboratory tests done at admission were within normal limits except for leukocytosis. Physical examination revealed abdominal distention, guarding and rebound tenderness. Abdominal ultrasound and oral contrast-enhanced CT showed a complex mass in the hypogastrium, with a typical configuration of intussusception. Emergent laparotomy revealed ileoileal invagination approximately 70 cm to the ileocecal valve but no lead point. A partial ileal resection was performed. Conclusion: This case shows that when intussusception is suspected, an abdominal ultrasound should be performed even in patients with atypical symptoms. CT may be used to confirm the diagnosis.
