Ileocecal Intussusception due to a Lipoma in an Adult

Abstract

While intestinal tumors are rare, small intestinal lipomas are even more uncommon benign neoplasms. They are usually asymptomatic, but lipomas larger than 2 cm may become symptomatic due to obstruction, bleeding, or intussusception. In this paper, US and CT findings of a lipoma located in the terminal ileum and causing ileocecal intussusception were discussed. We report a case of small bowel lipoma that became symptomatic due to intermittent obstruction episodes and ileocecal intussuception. If the diagnosis of intestinal lipoma had been made absolutely as in our case, they should be removed surgically in elective conditions.

Large intestinal lipoma: a case report and review of literature

“…It is not clear whether asymptomatic small lipomas require any intervention, but conservative treatment is often indicated. 5 The treatment depends essentially on the clinical picture, on the size and location of the lipoma and involves endoscopic or surgical excision.…”

Adult entero‐enteric intussusception secondary to lipoma

“…Unlike in children, adult intussusception is usually caused by a tumor acting as the lead point. Lipoma is one of the common causes . Preoperative diagnosis of adult intussusception is very challenging due to nonspecific nature of the symptoms.…”

Rare differential for large bowel obstruction

“…Unlike in children, intussusception in adults is commonly due to an organic aetiology . Benign causes of intussusception in adults include lipoma, Meckel’s diverticulum or adhesions . Lipoma is the most common benign tumour in both small and large bowel intussusception .…”

“…Benign causes of intussusception in adults include lipoma, Meckel’s diverticulum or adhesions . Lipoma is the most common benign tumour in both small and large bowel intussusception . Up to 50% of organic lesions causing intussusceptions in adults are malignant lesions .…”

“…7 Lipoma is the most common benign tumour in both small and large bowel intussusception. 7 Up to 50% of organic lesions causing intussusceptions in adults are malignant lesions. 4,8 Yakan et al conducted a retrospective review on patients over 18 years of age who had been diagnosed with an intestinal intussusception between 2000 and 2008.…”
