CT of the abdomen of a 25-year-old patient with known cystic fibrosis (CF) presents with distal intestinal obstruction syndrome. 

The liver is markedly nodular in contour in keeping with advanced cirrhosis and extensive dilated portosystemic collaterals are seen, consistent with portal hypertension. The spleen is also markedly enlarged. Also, note the complete fatty atrophy of the pancreas - a feature of cystic fibrosis.

The small bowel is dilated and fluid-filled bowel all the way to the distal ileum.
