Unusual ultrasound appearance of small bowel intussusception and secondary bowel obstruction in a child with Peutz-Jeghers syndrome.
Small bowel intussusception (SBI) in pediatric patients resolves spontaneously in the majority of cases. Pathologic small bowel intussusception with a lead point is rare in children. Ultrasound (US) is the preferred initial imaging study for the diagnosis of intussusception. We report a case of long-segment SBI and secondary bowel obstruction caused by a large hamartomatous polyp. This case emphasizes unique, atypical ultrasound findings that may be encountered in small bowel intussusception, with correlative radiographic, CT (computed tomography) and intra-operative findings. Increased awareness of these atypical imaging features can lead to early diagnosis and decrease the risk of potential complications including mesenteric venous thrombosis, bowel ischemia and necrosis.
