Imaging of duodenal lipoma, case report of a rare tumor of the gastro intestinal tract.

Duodenal lipoma is a rare tumor, and only a few cases have been reported in the literature. Despite some complicated cases, most patients are asymptomatic, which explains the frequency of incidental findings on imaging. The presented case involves a 77-year-old man who presented with malaise and dyspnea. A CT scan of the chest and abdomen was performed, leading to the incidental discovery of the lesion. Modern imaging techniques, including CT scans and MRI, are fundamental for ruling out differential diagnoses. These, combined with endoscopy and EUS, are key elements in reaching the final diagnosis. Treatment may include simple observation, endoscopic resection, or surgical resection, depending on the characteristics of the lesion.
