Characteristic CT features of heterotopic pancreas of the mesentery: “another pancreas” in the mesentery

PurposeTo evaluate computed tomography (CT) findings of heterotopic pancreas of the mesentery (HPM).MethodsTwo radiologists reviewed CT scans of seven patients with HPM to determine the location, relationship with the adjacent bowel, presence of a duct-like structure, and the enhancement pattern of HPM in consensus.ResultsAll HPMs were located in the jejunal mesentery and had morphologic features closely resembling those of the main pancreas and had unique relationship with the jejunum. Duct-like structures were observed in five lesions. The enhancement pattern varied.ConclusionIt is important to be aware of characteristic CT features of HPM to eliminate unnecessary surgeries.
