Apart the bowel inflammatory changes and obstruction without evident mechanical causes, what are the main findings probably accounting to the abdominal distension?
There is a massive portal vein thrombosis and consequent ascites in great volume.
There is a long segment of small bowel distention associated with wall thickening and mucosa enhancement, and no clear mechanical factor for the obstruction. The transition to normal bowel calibre is observed in the right iliac fossa. Proximal small bowel is mildly distended. The colon is unremarkable. No free gas to indicate perforation.
Multiple enlarged mesenteric lymph nodes, measuring up to 12 mm in short axis.
Extensive portal vein thrombosis from the vein formation to some middle sized intrahepatic ramifications in both lobes. Liver parenchyma is normal in appearance. Distended gallbladder. Multiple cysts in the spleen. The pancreas, kidneys and adrenal glands are normal.
Great volume of ascites. Bilateral pleural effusions associated with restrictive atelectasis within the lower pulmonary lobes.
