title: Jejunal lipoma concealing intestinal adenocarcinoma: don't always regard CT imaging features like lipoma as benign or pseudomalignant features.
abstract: Lipomas are benign submucosal tumors composed of mature adipose tissue. Some authors have described patients with persistent abdominal pain who were misdiagnosed as intestinal adenocarcinoma and the diagnosis turned out to be a lipoma on histological examination. We discuss the case of a 57-year-old woman presenting with abdominal pain for 4 weeks. Intestinal adenocarcinoma was found by double-balloon enteroscopy (DBE), but at first only lipoma was found by CT scan. Therefore we want to emphasize that lipoma should not always be regarded as pseudomalignant features, sometimes lipoma conceals intestinal adenocarcinoma, and DBE may be a better way to discover malignancy.
