Intussusception related to transverse colonic lipoma: a case report and review of the literature.

Lipomas are rare and benign colonic soft tissue lesions derived from mature adipocytes. Their poor clinical expression usually leads to a coincidental discovery during procedures like colonoscopy, imagery, surgery or autopsy. Due to their small size, a simple observation would usually be recommended. However, colonic lipomas with clinical symptoms or signs including abdominal pain, nausea, vomiting, diarrhea, anaemia or even intussusception would need invasive treatment. It is recommended to perform surgery to treat colonic lipomas that are >2 cm. Endoscopic procedures could be an interesting alternative for the future but would still require further investigation. We report the case of a 30-year-old patient with transverse colonic lipomas leading to obstruction of the descending colon by intussusception and continue by presenting a review of the current literature.
