There is a large right Spigelian hernia containing multiple loops of small bowel. A transition point is seen in the ileum as it enters the hernia. Dilated loops are seen within the hernia with further transition points within the small bowel as it exits and re-enters the hernia (Maydl's hernia). There is moderate surrounding soft tissue stranding in keeping with incarceration. The large bowel is collapsed.
Bilateral small (right: 5cm, left: 6cm) scarred kidneys and a right iliac fossa transplant kidney.
The remaining intra-abdominal viscera are unremarkable within the limitations of a non-contrast CT. No free intraperitoneal gas.
