Abnormal U and C-shape small bowel loops dilatation at the left lumbar region, with a diameter up to 4.0cm. These segments of dilated ileum have reduced bowel wall enhancement compared to the normal caliber and well-enhanced jejunum.
No intramural gas, pneumoperitoneum or portal venous gas. Moderate ascites.
Mesenteric infiltration/fluid with mesentery lymphadenopathy noted.
