Cysts in a Brunner’s GlanD Hamartoma: a Clue to DiaGnosis

(BGHs) are uncommon duodenal lesions, and account for approximately 5% of all duodenal masses (1). BGHs contain cysts on rare occasions, and only a very small number of cases of cystic BGH with accompanying computed tomography (CT) or magnetic resonance imaging (MRI) documentation have been reported (2-4). Imaging diagnosis of BGHs is usually a challenge, due to their nonspecific appearance. The presence of cysts can limit the differential diagnosis to cystic duodenal lesions. Characterization of the cysts in BGHs may facilitate their differentiation from other cystic duodenal lesions. Herein, we present a case of duodenal cystic BGH and review the cases reported to date, to determine the differences between the cysts of BGHs and those of other cystic duodenal lesions.
