Ectopic pancreas with lipoma in the distal jejunum: A case report

Ectopic pancreas is asymptomatic and mostly found in the stomach and proximal small bowel. It is difficult to distinguish ectopic pancreas with other submucosal tumors of the gastrointestinal (GI) tract on computed tomography (CT) without histological confirmation. The author encountered a case of ectopic pancreas coexisting with submucosal lipoma in the distal jejunum which was misdiagnosed as fat-containing submucosal tumor. The author reports the CT findings and reviews previously reported cases of ectopic pancreas coexisting with submucosal lipoma. The knowledge that ectopic pancreas can occur with benign lipoma, and its imaging features would be helpful for the diagnosis and management of patients.
