Cystic fibrosis and distal intestinal obstruction syndrome on computed tomography

A 20-year-old male with CF and with past history of DIOS presents with abdominal pain for 2 days and inability to stool. The CT scan shows a dilated distal small bowel (asterisk) filled with inspissated, fecalized content (arrow). The ascending colon (arrowhead) and descending colon (dashed arrow) are decompressed, suggesting small bowel obstruction in the setting of DIOS. Image B is a coronal reconstruction of the CT and shows the dilated distal small bowel (asterisk) filled with inspissated fecal-like intraluminal material (arrow).
