Computerized tomography providing definitive diagnosis of colonic lipoma: a case series.

Lipomas are common benign mesenchymal tumors. They can develop in virtually all organs throughout the body. Colonic lipomas are uncommon, benign, submucosal adipose tumors that are usually asymptomatic. Large lipomas can cause symptoms such as constipation, abdominal pain, rectal bleeding, and intussusception. We report a case series of 2 colonic submucosal lipomas with varying clinical presentations, elaborating the importance of computerized tomography imaging in the diagnosis and preoperative planning.
