The presented cases were initially diagnosed with ADM via ultrasound during an annual health check\u2010up and monitored for several years without further investigations due to the absence of significant changes or symptoms. Subsequently, one case was diagnosed with pancreaticobiliary maljunction (PBM) with a non\u2010dilated extrahepatic bile duct (EBD) after symptom onset, and underwent prophylactic laparoscopic cholecystectomy to avoid the risk of carcinogenesis. Although the other case remained asymptomatic, ultrasound later revealed far\u2010advanced gallbladder carcinoma with direct invasion into the liver and hepatic metastases, and endoscopic retrograde cholangiopancreatography identified PBM with a non\u2010dilated EBD. At laparotomy, she was found to have unresectable disease and died 4 months later. ADM associated with PBM has been recently reported. Consequently, evaluating the presence or absence of PBM is essential for determining an appropriate treatment strategy when diagnosing ADM.<\/jats:p>","DOI":"10.1002\/jcu.70127","type":"journal-article","created":{"date-parts":[[2025,11,20]],"date-time":"2025-11-20T07:50:10Z","timestamp":1763625010000},"page":"1011-1015","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Pancreaticobiliary Maljunction With a Non\u2010Dilated Extrahepatic Bile Duct Masked by Adenomyomatosis: A Potential Cause of Unresectable Gallbladder Carcinoma"],"prefix":"10.1002","volume":"54","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5298-6412","authenticated-orcid":false,"given":"Taketoshi","family":"Fujimoto","sequence":"first","affiliation":[{"name":"Department of Surgery Hiratsuka Gastroenterological Hospital  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yo","family":"Kato","sequence":"additional","affiliation":[{"name":"Department of Pathology The Cancer Institute of JFCR  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,11,19]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/jcu.24020"},{"key":"e_1_2_8_3_1","first-page":"511","article-title":"In\u2010Situ Carcinoma Found in Adenomyomatosis of the Gallbladder Associated With Pancreaticobiliary Maljunction: A Case Report","volume":"13","author":"Fujimoto T.","year":"2011","journal-title":"Hepato\u2010Biliary\u2010Pancreatic Imaging"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jviscsurg.2017.06.004"},{"key":"e_1_2_8_5_1","first-page":"517","article-title":"Imaging Features of the Gallbladder Wall in Patients With Anomalous Arrangement of the Pancreaticobiliary System","volume":"5","author":"Igarashi H.","year":"1991","journal-title":"Journal of the Japan Biliary Association"},{"key":"e_1_2_8_6_1","first-page":"633","article-title":"Clinicopathological Features of Gallbladder Cancer With Adenomyomatosis","volume":"28","author":"Kin T.","year":"2014","journal-title":"Journal of the Japan Biliary Association"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.21037\/atm-20-4897"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10396\u2010022\u201001272\u2010w"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v18.i26.3409"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1746.1998.tb00634.x"},{"key":"e_1_2_8_11_1","first-page":"33","article-title":"Early Detection of Anomalous Pancreaticobiliary Ductal Union Based on the Ultrasonographic Findings of Thickened Inner Hypoechoic Layer and Adenomyomatosis of the Gallbladder","volume":"17","author":"Yanagawa N.","year":"2007","journal-title":"Journal of Asahikawa Kosei General Hospital"}],"container-title":["Journal of Clinical Ultrasound"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jcu.70127","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/jcu.70127","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jcu.70127","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,7,13]],"date-time":"2026-07-13T08:25:05Z","timestamp":1783931105000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/jcu.70127"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,11,19]]},"references-count":10,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2026,5]]}},"alternative-id":["10.1002\/jcu.70127"],"URL":"https:\/\/doi.org\/10.1002\/jcu.70127","archive":["Portico"],"relation":{},"ISSN":["0091-2751","1097-0096"],"issn-type":[{"value":"0091-2751","type":"print"},{"value":"1097-0096","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,11,19]]},"assertion":[{"value":"2025-07-30","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-10-22","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-11-19","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
