Choledochocele type (a) are cystic dilatations of a segment of the intra-ampullary bile duct and are located proximal to the ampullary orifice. Choledochocele type (b) are diverticula of the intra-ampullary common channel and are located distal to the ampullary orifice. In duodenal duplication cyst (c), the cyst wall is lined by muscularis propria and is in continuation with the duodenal muscle layer.

Magnetic resonance cholangiopancreaticography demonstrated a common channel at the ampulla with communication with the cyst (B). In one coronal T2W sequence, the cyst was seen in D1 (A), and in another sequence, it was in D2 extending to D3 (B) suggestive of mobile cyst. The common bile duct diameter also varied between sequences from 8 to 12 mm suggestive of dynamic compression. CBD, common bile duct.
