A case of superior mesenteric artery syndrome characterized by deep forward bending posture in a cross-legged position on the floor.

A 17-year-old healthy male presents with severe epicardial pain and frequent vomiting 1 h after lunch, preferring to sit cross-legged on a stretcher with a deep forward bending posture along with difficulty lying down. SMA syndrome should be considered in the differential diagnosis of patients demonstrating such posture.
