Postoperative intussusception is a rare complication with a reported rate of 0.01-0.25% in children following laparotomy, accounting for 5-10% of postoperative bowel obstruction. We present a case of a 6-month-old infant with increasing abdominal fullness over several weeks who was found to have a large left renal mass. Following surgical resection of an atypical cellular form of Congenital Mesoblastic Nephroma, the patient developed abdominal distension and was presumed to have a postoperative ileus. Due to unexplained persistent hypertension following surgery, MR Angiogram of the Abdomen was performed to evaluate the renal arteries. On this MR exam, a right lower quadrant ileocolic intussusception was identified. Air enema intussusception reduction attempt was unsuccessful, and laparotomy was performed with successful reduction. We review the literature on pediatric postoperative intussusception including the variety of initial surgical operations, clinical symptoms, intussusception type, treatment, and patient outcomes.

Late-presenting or recurrent diaphragmatic defects can pose a diagnostic challenge due to varying clinical presentations. Current diagnostic approaches include plain film radiograph for initial assessment, with other imaging modalities such as fluoroscopy, ultrasound, CT and MRI mainly employed for troubleshooting. As a radiation-free modality, MRI can provide a more definitive diagnosis in particular cases due to its ability to visualize discontinuity of the diaphragm (distinguishing it from eventration), hernia contents, defect location and size. In this exhibit, we will: 1. Review the normal appearance of the diaphragm. 2. Share our institutional MRI protocol for optimal evaluation of the diaphragm, including use of CINE steady state free precession sequences and use of negative slice spacing in T2 weighted images. 3. Discuss important postnatal MR imaging findings of late presenting and recurrent diaphragmatic hernias in children. 4. Describe potential diagnostic pitfalls in the imaging of the diaphragm.
