We report a case of a 21-year-old female patient from Skardu, Pakistan. The patient shows an unusual presentation that makes the diagnosis quite tricky. The symptoms include dull, persistent right hypochondrial pain, nausea, and vomiting without any signs of jaundice or fever. Moreover, the blood tests revealed only a mild increase in eosinophil count, just above the borderline, and completely normal liver function, a distinguishing feature of parasitic infections. Ultrasound showed a dilated bile duct containing a roundworm, indicating a parasite infection. Initially, the patient was given deworming medication. Furthermore, Magnetic resonance cholangiopancreatography (MRCP) findings were consistent with biliary ascariasis characterized by the presence of Ascaris within the hepatic biliary channels causing its significant dilatation. This case report highlights that lab reports can sometimes be misleading when making a diagnosis of biliary ascariasis. Additionally, there is a need for improvement in the healthcare system and sanitation.<\/jats:p>","DOI":"10.1093\/omcr\/omaf268","type":"journal-article","created":{"date-parts":[[2025,11,18]],"date-time":"2025-11-18T12:51:39Z","timestamp":1763470299000},"source":"Crossref","is-referenced-by-count":0,"title":["Biliary ascariasis without cholangitis: an unusual presentation in an endemic region"],"prefix":"10.1093","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-2080-8866","authenticated-orcid":false,"family":"Nabil","sequence":"first","affiliation":[{"name":"Department of Medicine, Allama Iqbal Medical College, Jinnah Hospital , Lahore, Punjab 54700 ,","place":["Pakistan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muhammad Ashar","family":"Zohaib","sequence":"additional","affiliation":[{"name":"Department of Medicine, Allama Iqbal Medical College , Lahore, Punjab 54700 ,","place":["Pakistan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-6017-9029","authenticated-orcid":false,"given":"Muhammad","family":"Zubair","sequence":"additional","affiliation":[{"name":"Department of Medicine, Allama Iqbal Medical College , Lahore, Punjab 54700 ,","place":["Pakistan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Urvah","family":"Shafique","sequence":"additional","affiliation":[{"name":"Department of Medicine, Allama Iqbal Medical College , Lahore, Punjab 54700 ,","place":["Pakistan"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2627-685X","authenticated-orcid":false,"given":"Javed","family":"Iqbal","sequence":"additional","affiliation":[{"name":"Nursing Department Hamad Medical Corporation Doha, Department of Nursing , P.O Box 3050 , Doha,","place":["Qatar"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Asraf","family":"Hussain","sequence":"additional","affiliation":[{"name":"Chitwan Medical College, Chitwan Bharatpur Nepal , Bharatpur, P.O Box 44200 ,","place":["Nepal"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,12,26]]},"reference":[{"key":"2025122602500932400_ref1","doi-asserted-by":"publisher","first-page":"916","DOI":"10.3390\/medicina60060916","article-title":"Biliary ascariasis in a Pediatric patient in Lithuania: case report and literature review","volume":"60","author":"Rokait\u0117","year":"2024","journal-title":"Med Kaunas Lith"},{"key":"2025122602500932400_ref2","doi-asserted-by":"publisher","first-page":"500","DOI":"10.55519\/JAMC-03-10212","article-title":"Gall bladder ascariasis: a rare entity","volume":"35","author":"Akbar","year":"2023","journal-title":"J Ayub Med Coll Abbottabad JAMC"},{"key":"2025122602500932400_ref3","doi-asserted-by":"publisher","first-page":"e33323","DOI":"10.7759\/cureus.33323","article-title":"A case report on biliary ascariasis","volume":"15","author":"Kolleri","year":"2023","journal-title":"Cureus"},{"key":"2025122602500932400_ref4","doi-asserted-by":"publisher","first-page":"e60537","DOI":"10.7759\/cureus.60537","article-title":"An interesting case of cholangitis","volume":"16","author":"Reddy","year":"2024","journal-title":"Cureus"},{"key":"2025122602500932400_ref5","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1155\/2022\/8201398","article-title":"Successful Management of Biliary Ascariasis in a high-endemic zone and low-resource setting in Ethiopia","volume":"2022","author":"Asfaw","year":"2022","journal-title":"Case Rep Infect Dis"},{"key":"2025122602500932400_ref6","doi-asserted-by":"publisher","first-page":"e239784","DOI":"10.1136\/bcr-2020-239784","article-title":"Massive biliary ascariasis: an unusual cause of acute cholangitis","volume":"14","author":"Rujeerapaiboon","year":"2021","journal-title":"BMJ Case Rep"},{"key":"2025122602500932400_ref7","doi-asserted-by":"publisher","first-page":"e32545","DOI":"10.7759\/cureus.32545","article-title":"An overview of ascariasis involvement in gallbladder disease: a systematic review of case reports","volume":"14","author":"Inyang","year":"2022","journal-title":"Cureus"},{"key":"2025122602500932400_ref8","doi-asserted-by":"publisher","first-page":"164","DOI":"10.1016\/j.ajg.2020.11.002","article-title":"Treatment response and long-term outcomes in biliary ascariasis: a prospective study","volume":"22","author":"Patra","year":"2021","journal-title":"Arab J Gastroenterol"},{"key":"2025122602500932400_ref9","doi-asserted-by":"publisher","first-page":"E195","DOI":"10.1055\/a-2258-8436","article-title":"Biliary ascariasis: extraction","volume":"56","author":"Rahimi","year":"2024","journal-title":"Endoscopy"},{"key":"2025122602500932400_ref10","doi-asserted-by":"publisher","first-page":"83","DOI":"10.51866\/cr1078","article-title":"Biliary ascariasis -
