Small intestinal submucosal lipoma: a rare cause of secondary intussusception in a child

Abstract

Background Intestinal 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 presentation We 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. Conclusions Small 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.

Unsuspecting Lead Points Causing Nonobstructing Intussusceptions in Pediatric Patients Presenting with Chronic Pain Abdomen

“…17 In longitudinal view, peripheral hypoechoic and central echogenic area is seen, termed as pseudokidney sign. 18 Central echogenecity of pseudokidney sign is contributed by mesentery due to its fat content. Color Doppler study has an important role in detection of bowel viability.…”

Unusual presentation of ileal intussusception due to submucosal lipoma in a child and its management

“…Intestinal lipomas, although rare, have been previously reported to cause intussusception in children. [ 4 ] There are three pathological types of intestinal lipomas: (i) intermuscular type; (ii) subserosal type; and (iii) submucosal type. The tumors arise from the submucosa in 90% of cases, while the remainders are usually subserosal.…”

“…The tumors arise from the submucosa in 90% of cases, while the remainders are usually subserosal. [ 4 ] In a systematic review of 147 cases of small bowel lipoma over 20 years, there were 138 adults and only 9 children with small bowel lipomas. [ 5 ] For pediatric age group, small intestinal lipomas, median age at diagnosis is 8 years with a range from 4 to 14 years and highly echoic masses on ultrasound or appear as round or oval, well-defined, hypointense, and intraluminal masses on computed tomography scans.…”

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

“…They are usually difficult to identify and diagnose before surgery. Cheikhrouhou et al mentioned that only 7 cases of intussusception due to lipoma in pediatric patients were reported so far, with a median age of 8 years [ 3 ]. Manouras et al showed that lesions smaller than 1 cm are considered asymptomatic, and lipomas are more likely to be symptomatic when the diameter exceeds 2 cm.…”
