[X-ray computed tomography of duodenal lipoma]

Duodenal lipoma is a rare, often asymptomatic tumor; the circumstances of its discovery have become more frequent as CT examinations are more commonly performed. The merits of a CT examination for this condition is to allow both a positive diagnosis and the follow-up of these fatty tumors which have very few clinical expressions, thus avoiding complementary examinations or even useless laparotomies. The authors describe three cases of incidental discovery of duodenal lipomas.
