Case Report: It's a Small Whirl Afterall.

Unlabelled: Recognition of the whirl sign on computed tomography (CT) imaging can improve patient outcomes in those presenting with small bowel obstruction (SBO). In the case highlighted in this report, a 40-year-old woman with a remote history of gastric bypass presented to the emergency department (ED) with four hours of abdominal pain and vomiting. Findings on the initial CT of the abdomen and pelvis were suggestive of SBO with a whirl sign pattern.
