Abstract
Superior mesenteric artery (SMA) syndrome is a rare cause of intestinal obstruction, especially in children, whereas intussusception is far more common. We report the case of a child, who after an episode of acute weight loss presented with features suggestive of SMA syndrome. This child subsequently was shown at operation to have disseminated lymphoma causing a secondary high jejunal intussusception and tumor involvement of retroperitoneal lymph nodes causing compression of the third part of the duodenum. This case emphasizes that the SMA syndrome should be considered a sign rather than a diagnosis in itself. As such, an active search should be made to determine the cause of the condition. Routine preoperative imaging is recommended.
