HTLV\u20101 has also been implicated in the pathogenesis of various autoimmune rheumatic diseases, and its association with the autoimmune disorders of the gastrointestinal track is less well understood. Our patient, a 26\u2010year\u2010old previously healthy female, presented with recurrent, progressively worsening chronic abdominal pain and persistent liver test abnormalities. Initially diagnosed with acute acalculous cholecystitis and autoimmune hepatitis (AIH), her liver tests continued to exhibit a predominantly cholestatic pattern. This prompted further advanced imaging, and magnetic resonance cholangiopancreatography ultimately confirmed a diagnosis of primary sclerosing cholangitis (PSC). Complicating her condition further, she developed lower extremity weakness, initially attributed to axonal Guillain\u2013Barr\u00e9 syndrome, which unfortunately did not respond to standard treatment. After a year marked by progressive clinical decline with repeated and prolonged hospitalizations due to fever of unknown origin, an extensive diagnostic workup ultimately led to a diagnosis of HTLV\u20101 myelopathy, along with AIH\u2010PSC overlap syndrome. This case highlights the diagnostic challenges associated with the multisystem involvement of HTLV\u20101. Notably, our patient\u2019s presentation was not consistent with classic HTLV\u20101 myelopathy rather a subtype with rapidly progressive symptoms and flaccid as opposed to spastic paresis. The association between HTLV\u20101 infection and autoimmune cholangiopathy is exceptionally rare. To the best of our knowledge, our case represents only the second reported instance of autoimmune cholangiopathy associated with HTLV\u20101 myelopathy and the first reported case of AIH\u2010PSC overlap syndrome associated with HTLV\u20101 myelopathy. This underscores the need for heightened clinical awareness of potential hepatic immune manifestations in patients with HTLV\u20101 infection, even in the absence of classic neurologic symptoms at initial presentation.<\/jats:p>","DOI":"10.1155\/crdi\/7381720","type":"journal-article","created":{"date-parts":[[2025,9,9]],"date-time":"2025-09-09T06:21:42Z","timestamp":1757398902000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Human T\u2010Lymphotropic Virus Type 1\u2013Associated Myelopathy With Autoimmune Cholangiopathy: An Unusual Immune Conundrum in a Young Patient"],"prefix":"10.1155","volume":"2025","author":[{"given":"Aida","family":"Saad","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yamna","family":"Jadoon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5577-6867","authenticated-orcid":false,"given":"Riffat","family":"Sabir","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,9,8]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.patbio.2008.02.015"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.3389\/fmicb.2012.00388"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.qai.0000557944.75507.a6"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/00042560-199802010-00011"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.3390\/v8010005"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.63.11.1560"},{"key":"e_1_2_10_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/s0140-6736(85)92734-5"},{"key":"e_1_2_10_8_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12977-019-0499-5"},{"key":"e_1_2_10_9_2","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.58.5.815"},{"key":"e_1_2_10_10_2","doi-asserted-by":"publisher","DOI":"10.1212\/cpj.0000000000000832"},{"key":"e_1_2_10_11_2","doi-asserted-by":"publisher","DOI":"10.3390\/v14010136"},{"key":"e_1_2_10_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.hepres.2004.12.003"},{"key":"e_1_2_10_13_2","first-page":"2107","article-title":"Asymptomatic Primary Biliary Cirrhosis in HTLV-I-Associated Myelopathy","volume":"88","author":"Ijichi T.","year":"1993","journal-title":"American Journal of Gastroenterology"},{"key":"e_1_2_10_14_2","doi-asserted-by":"publisher","DOI":"10.2169\/internalmedicine.6793-20"},{"key":"e_1_2_10_15_2","doi-asserted-by":"publisher","DOI":"10.1097\/00004836-199104000-00017"},{"key":"e_1_2_10_16_2","doi-asserted-by":"publisher","DOI":"10.2169\/internalmedicine.32.449"},{"key":"e_1_2_10_17_2","doi-asserted-by":"publisher","DOI":"10.1097\/md.0000000000026236"},{"key":"e_1_2_10_18_2","doi-asserted-by":"publisher","DOI":"10.1155\/2013\/198070"},{"key":"e_1_2_10_19_2","doi-asserted-by":"publisher","DOI":"10.21037\/tgh-24-140"}],"container-title":["Case Reports in Infectious Diseases"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crdi\/7381720","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1155\/crdi\/7381720","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1155\/crdi\/7381720","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,17]],"date-time":"2026-03-17T17:55:32Z","timestamp":1773770132000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/crdi\/7381720"}},"subtitle":[],"editor":[{"given":"Piyush","family":"Baindara","sequence":"additional","affiliation":[],"role":[{"role":"editor","vocabulary":"crossref"}]}],"short-title":[],"issued":{"date-parts":[[2025,1]]},"references-count":19,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2025,1]]}},"alternative-id":["10.1155\/crdi\/7381720"],"URL":"https:\/\/doi.org\/10.1155\/crdi\/7381720","archive":["Portico"],"relation":{},"ISSN":["2090-6625","2090-6633"],"issn-type":[{"value":"2090-6625","type":"print"},{"value":"2090-6633","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,1]]},"assertion":[{"value":"2024-10-05","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-08-19","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-09-08","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"7381720"}}
