CT colonogram

Numerous fat density polypoid lesions arise from the mucosal surface of the large bowel, with no territorial predilection. No suspicious colonic lesions are detected. Unremarkable appearances elsewhere.

Case Discussion

Lipomas may be found within the GI tract but there are very few reports of widespread lipomatosis such as in this case. Cases have been reported of associated lipomas in skeletal muscle and omentum. They mimic other causes of polyposis but it is important to differentiate lipomas from other tumours. Other differentials may predispose to malignancy and require aggressive treatment whereas lipomas can be managed conservatively if there are no complications. The cause of multiple gastrointestinal lipomas is unknown. They may remain asymptomatic or can present with non-specific abdominal pain, nausea and vomiting. The presentation may be acute with complications such as obstruction, bleeding, intermittent abdominal pain and intussusception.
