case_images: The repeat CT scan (Figure 5) revealed an irregular lobulated mass with central necrosis at the ileocaecal junction associated with small bowel obstruction.
case_images: A persistent periappendiceal collection is again seen. New findings include small bowel obstruction as well as nodules adjacent to the collection and along the track of previous drain insertion.
