Abstract
BackgroundIntestinal lipomas are benign, non-epithelial, intestinal tumors with an exceptionally rare localization at the ileum. Lipomas in the small intestine occur mainly in elderly patients and seldom occur in childhood. They are frequently asymptomatic, possibly due to their slow growth. These tumors may act as a lead point of intussusception.Case presentationWe report a rare case of double compounded ileo-ileal intussusception due to a submucosal intestinal lipoma in an 8-year-old female. To our knowledge, this is only the seventh pediatric case to be reported in the medical literature.ConclusionsSmall intestinal submucosal lipoma should be considered in case of intussusception in pediatric patients. Surgical resection seems sufficient in case of symptomatic intestinal lipoma with low morbidity.

Intestinal lipomas are benign, non-epithelial, intestinal tumors with an exceptionally rare localization at the ileum
We describe a pediatric case of intussusception secondary to a gastrointestinal tract (GIT) lipoma and present a review of the literature on small bowel intussusception due to gastrointestinal lipomas
Secondary intussusceptions are caused by pathologic lead points (PLPs) (such as Meckel’s diverticulum, Fig. 2 Abdominal ultrasound revealed an intussusception with typical target sign duplication, polyps, and tumors) and represent 2.2–15% of cases [5, 6]
Summary
Lipomas can develop in virtually all organs. They are benign soft tissue tumors derived from mature adipocytes. Lipomas of the gastrointestinal tract (GIT) are rare [1]. Rare, have previously been reported as the leading point of intussusception [4]. We describe a pediatric case of intussusception secondary to a GIT lipoma and present a review of the literature on small bowel intussusception due to gastrointestinal lipomas. Clinical examination revealed tenderness at the right iliac fossa without abdominal distension or signs of peritoneal irritation. Abdominal X-ray revealed no specific bowel gas pattern, but gaseous distension of several small bowel loops (Fig. 1). Abdominal ultrasound revealed the typical target sign in the right lower abdomen suggestive of ileocolic intussusception, extending for approximately 9.6 cm. In. The patient underwent emergency exploratory laparotomy, which revealed a long intussuscepted ileal tract (Fig. 3). Histopathological examination confirmed the diagnosis of a submucosal intestinal lipoma (Fig. 5). The postoperative course was uneventful and the patient was discharged after 1 week
