What imaging finding is associated with midgut volvulus?

• A. Double bubble sign
• B. Inspiratory stridor
• C. Coffee bean sign
• D. Barium swallow corkscrew

Answer: (D)

The imaging finding associated with midgut volvulus is the "barium swallow corkscrew" sign. This sign is indicative of a twisting of the bowel, which can occur in the setting of midgut malrotation. When a patient undergoes barium swallow imaging, the barium outlines the esophagus and stomach, and the twisted bowel appearance can mimic a corkscrew.

In contrast, the double bubble sign is typically associated with duodenal atresia, displaying the air-filled stomach and proximal duodenum. Inspiratory stridor is a clinical symptom often linked to upper airway obstruction and is not an imaging finding. The coffee bean sign appears in cases of sigmoid volvulus, indicating the characteristic distension of the colon rather than midgut involvement.

Understanding these associations helps in diagnosing conditions related to bowel obstruction and volvulus through appropriate imaging studies, with the barium swallow corkscrew sign specifically highlighting midgut volvulus due to its unique representation of bowel rotation.
