Pedunculated lipoma causing colo-colonic intussusception: a rare case report

Area of Science:

• Gastroenterology
• Surgical Oncology

Background:

• Intussusception is a rare cause of intestinal obstruction in adults, accounting for less than 1% of cases.
• Colonic lipomas are infrequent nonepithelial neoplasms, often asymptomatic and discovered incidentally.

Observation:

• A 55-year-old male presented with acute abdominal pain, vomiting, and distension.
• Imaging revealed a target sign consistent with intussusception, later confirmed during surgery.
• A large submucosal lipoma was identified as the cause of colo-colonic intussusception.

Findings:

• Submucosal lipoma is a rare etiology for adult intussusception and bowel obstruction.
• Computed tomography (CT) and magnetic resonance imaging (MRI) are crucial for diagnosing abdominal lipomas.
• Surgical resection is the definitive treatment for symptomatic colonic lipomas causing intussusception.

Implications:

• This case highlights the diagnostic challenges of adult intussusception due to colonic lipomas.
• Early diagnosis and surgical intervention are critical for favorable outcomes.
• Further research into the management of rare adult intussusception cases is warranted.
