# Small bowel lipoma and intussusception: a case report

## TL;DR

This case report describes a rare instance of small bowel intussusception in an adult caused by a lipoma, highlighting the importance of considering lipomas as a potential cause.

## Contribution

The novelty lies in presenting a rare case of adult intussusception caused by a small bowel lipoma.

## Key findings

- Intussusception in adults is rare and often secondary to structural lesions.
- Small bowel lipoma can act as a lead point for intussusception.
- Clinical suspicion is crucial for diagnosing small bowel intussusception in adults.

## Abstract

Intussusception is defined as the telescoping of bowel into itself. Intussusception is the leading cause of bowel obstruction in children, but it is rare in adults [1, 2]. It has a pathological intramural or extramural lead point. In adults, it accounts for 1%–5% of cases of bowel obstruction [3, 4]. Unlike presentation in the paediatric population of cramping abdominal pain, bloody mucus, and palpable mass in right iliac fossa, presentation in adults can be more varied and non-specific [1, 4]. Hence, diagnosis of small bowel intussusception (SBI) can be challenging, requiring a higher degree of clinical suspicion [5]. While cases of paediatric intestinal intussusception are often primary, most adult cases are secondary to structural lesions [5]. This case is of a 57-year-old lady who presented with SBI secondary to a small bowel lipoma (SBL), reflecting the importance of considering SBL as a differential in the causes of SBI.
