To our knowledge, there are approximately 30 reported cases of drug\u2010induced liver injury (DILI) associated with the use of methimazole in the literature. DILI is a challenging diagnosis and can often mimic many forms of acute and chronic hepatitis. The pattern of liver injury can be hepatocellular, cholestatic, or mixed in nature. The R\u2010value is a useful tool for characterizing the pattern of liver injury, while the Roussel Uclaf Causality Assessment Method (RUCAM) aids with quantifying the likelihood of DILI. The updated version of RUCAM from 2016 was used in this report. We present a case of a 72\u2010year\u2010old female who developed cholestatic DILI secondary to methimazole with a calculated RUCAM score of 8, initially obscured by both imaging and endoscopic findings concerning for hepatobiliary obstruction.<\/jats:p>","DOI":"10.1002\/jgh3.13042","type":"journal-article","created":{"date-parts":[[2025,3,3]],"date-time":"2025-03-03T11:47:10Z","timestamp":1741002430000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["<scp>Methimazole\u2010induced<\/scp> cholestasis initially obscured by an incidental finding of a large periampullary diverticulum: A case report with reference to the updated <scp>RUCAM<\/scp> of 2016"],"prefix":"10.1002","volume":"9","author":[{"given":"Salomon","family":"Chamay","sequence":"first","affiliation":[{"name":"Division of Internal Medicine, Department of Medicine St. Barnabas Hospital  Bronx New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ari","family":"Alter","sequence":"additional","affiliation":[{"name":"Touro University  New York New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rooshi","family":"Parikh","sequence":"additional","affiliation":[{"name":"CUNY School of Medicine  New York New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3508-2005","authenticated-orcid":false,"given":"Shivam","family":"Khatri","sequence":"additional","affiliation":[{"name":"CUNY School of Medicine  New York New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deepa","family":"Budh","sequence":"additional","affiliation":[{"name":"Division of Internal Medicine, Department of Medicine St. Barnabas Hospital  Bronx New York USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitchell","family":"Spinnell","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Department of Medicine Englewood Hospital  Englewood New Jersey USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,2,24]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra1816149"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.2165\/00002018-200730040-00001"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41572-019-0105-0"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.18632\/oncotarget.6144"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.3390\/ijms17010014"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/cld.615"},{"key":"e_1_2_9_8_1","first-page":"1239","article-title":"Epidemiology and Management of Drug\u2010induced Liver Injury: Importance of the Updated RUCAM","volume":"11","author":"Kobayashi T","year":"2023","journal-title":"J.
