Small bowel obstruction with small bowel feces sign on CT scan

Small bowel obstruction with small bowel feces sign on CT scan
A CT scan of the abdomen (A) shows a zone of transition at the site of a small bowel obstruction (arrowhead). A small bowel feces sign is present in the small bowel adjacent to the obstruction (arrow), and the remaining upstream small bowel is dilated (dashed arrow).
(B) is a coronal reconstruction of the CT and shows a fluid-filled and distended stomach (arrow) despite the presence of a nasogastric tube. Both the ascending colon and descending colon are decompressed (arrowheads).
CT: computed tomography.
