Dacron grafts have been used as a conduit for large caliber arteries for many years successfully. However, these grafts can undergo complications such as aneurysm formation, rupture, and failure. Evaluation of these complications are of paramount importance because of its tendency to rupture and cause death. Imaging plays an important role in identifying and monitoring of these complications, and also provides a road map to the vascular surgeons for early intervention and revascularization.

A rare case of Brunner’s gland hyperplasia mimicking duodenal malignancy is reported. A 21-year old man had a lesion in the second portion of the duodenum on endoscopy. The biopsy specimen suggested moderate and chronically active duodenitis. However, since the CT features strongly suggested malignancy, pyloroduodenotomy, excision of the lesion and Heineke-Mikulicz pyloroplasty was performed. The final pathological diagnosis was Brunner’s gland hyperplasia.
