An intussusception caused by a rare transverse colon lipoma: Case report

Introduction: Intestinal lipoma is a rare benign tumor with a reported incidence of 0.2 % to 4.4 %. It is seen mainly in patients aged 50 to 70 years. Intestinal lipoma as a pathological lead point of intussusception is rare. There are few reports of colic lipoma in children. Presentation of case: We reported a 7-year-old girl with a 4-year history of intermittent abdominal pain. Ultrasound examination showed a homogeneous hyperechoic mass near the distal transverse colon, which was similar to the surrounding lipid tissue. Histopathological examination confirmed the diagnosis of intestinal lipoma. Discussion: Colonic lipoma is very rare in children. If intussusception occurs repeatedly, or if it occurs in older children, we should consider the presence of pathological lead point. Early diagnosis and immediate surgical intervention are the key factors to a successful outcome. Conclusion: In this case we report a pediatric case of intussusception secondary to colonic lipoma, and describe imaging and pathologic signs suggestive of intestinal lipoma.
