We present a case study of a 47-year-old woman with cholecystolithiasis, in whom a dia­gnostic examination showed a solid-cystic lesion in the subhepatic region, oppressing the biliary tract. After completing examinations with imaging techniques (ultrasound, CT, MR) and endoscopic retrograde cholangiopancreatography (ERCP) with biliary drainage through a duodeno-biliary stent, the patient was directly indicated for a resection. Mucinous neoplasia of the biliary tract or cystic anomalies were considered as possible dia­gnoses prior to the surgery. The lesion was resected together with the adjacent gallbladder and biliary ducts. Surprisingly, the histological examination of the resected tissue showed a non-tumorous affection – adenomyomatosis of extrahepatic biliary ducts.
