Identify the radiological image given below.
Show Hint
Coiled-spring folds and a crescent of contrast around a luminal mass mean one bowel loop has telescoped.
Updated On: Jun 23, 2026
- Intussusception
- Carcinoma colon
- Sigmoid volvulus
- Diverticulitis

The Correct Option is A
Solution and Explanation
Step 1: Read the contrast study. There is a rounded soft-tissue mass within the bowel lumen with contrast curving around its leading edge, the 'claw' or 'crescent' sign, and a coiled-spring appearance of mucosal folds.
Step 2: Interpret. One segment of bowel has telescoped into the next, the classic picture of intussusception.
Step 3: Tie in the clinical clue. Typically an infant with episodic colicky pain, screaming episodes, and passage of blood and mucus ('redcurrant jelly' stool). The abdominal radiograph may show absent bowel gas in the right iliac fossa with a soft-tissue mass.
Why the others are wrong: Carcinoma colon gives an 'apple-core' annular stricture. Sigmoid volvulus gives a 'coffee-bean' loop arising from the pelvis. Diverticulitis shows outpouchings with localised inflammation, none of which is a telescoped target.
