Computed tomographic and magnetic resonance imaging findings of asymptomatic intra-abdominal gastrointestinal system...

Lipomas are common benign mesenchymal neoplasms documented in literature. This study aimed to describe the computed tomographic (CT) and magnetic resonance imaging (MRI) findings of gastrointestinal system lipomas, all of which are incidentally found in routine abdominal imaging studies. Lipomas were depicted as homogeneous, nonenhancing, well-marginated lesions consistent with adipose tissue on CT and MRI. The density measurements on CT images consistent with fat are virtually diagnostic. Lipomas can incidentally be found and should be considered in the differential diagnosis of soft tissue gastrointestinal system-related masses. Computed tomographic or MRI examinations can correctly diagnose a lipoma nonoperatively, thereby allowing better treatment planning.
