Enterolith: (a and b) Erect and supine plain abdominal radiograph in a 56-year-old man presenting with abdominal distension, vomiting, and severe lower abdominal pain demonstrates dilatation of the small and large bowel loops with associated air-fluid levels concerning for obstruction. A lamellated calcific shadow (arrow) is noted in the left lower quadrant. Computed tomography scan (c-e) performed subsequently confirms an enterolith (arrows) in the distal descending colon which resulted in bowel obstruction. No mass was identified and the patient was managed conservatively with endoscopic fragmentation and removal of the enterolith. Plain abdominal radiograph performed subsequently demonstrated complete removal of the enterolith and interval improvement of bowel obstruction (f).
