Intestinal Ultrasound of Adult Small Bowel Intussusception Caused by a Polyp: A Case Report.

In patients with nonspecific abdominal symptoms, this may expedite CT confirmation, support appropriate surgical referral, and improve diagnostic confidence and overall clinical decision-making and management.
