A 2-month-old, intact, male French Bulldog presented with a greenish-yellow discharge dripping from the umbilicus since birth. Complete blood count and serum biochemistry were within normal limits, but serum alkaline phosphatase activity was mildly elevated. A positive contrast cystogram was performed to rule out a patent urachus and confirmed the presence of a vesicourachal diverticula, a type of urachal anomalies. An abdominal ultrasound and computed tomography fistulogram demonstrated a communication between the umbilicus and common bile duct, which suggested an umbilicobiliary fistula. Surgical correction of the umbilicobiliary fistula and vesicourachal diverticula was successfully performed with an uneventful recovery. Histological analysis of the fistulous tract demonstrated a cuboidal\/columnar lining epithelium that transitioned to squamous epithelium near the umbilicus. Agenesis of the gallbladder was noted. The application of multiple imaging techniques in the diagnosis and surgical correction of these congenital abnormalities (umbilicobiliary fistula, gallbladder agenesis, and vesicourachal diverticula) was beneficial for treatment planning and outcome.<\/jats:p>","DOI":"10.3390\/ani15243626","type":"journal-article","created":{"date-parts":[[2025,12,17]],"date-time":"2025-12-17T09:43:46Z","timestamp":1765964626000},"page":"3626","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Concurrent Congenital Umbilicobiliary Fistula and Vesicourachal Diverticula in a Dog"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7342-7879","authenticated-orcid":false,"given":"Sathidpak N.","family":"Assawarachan","sequence":"first","affiliation":[{"name":"Department of Companion Animal Clinical Sciences, Faculty of Veterinary Medicine, Kasetsart University, 50 Phaholyothin Rd., Lat Yao, Jatujak, Bangkok 10900, Thailand"},{"name":"Endocrinology and Gastroenterology Unit, Kasetsart University Veterinary Teaching Hospital, Faculty of Veterinary Medicine, Kasetsart University, 50 Phaholyothin Rd., Lat Yao, Jatujak, Bangkok 10900, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Veerada","family":"Wachirodom","sequence":"additional","affiliation":[{"name":"Endocrinology and Gastroenterology Unit, Kasetsart University Veterinary Teaching Hospital, Faculty of Veterinary Medicine, Kasetsart University, 50 Phaholyothin Rd., Lat Yao, Jatujak, Bangkok 10900, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Benjang","family":"Hakhen","sequence":"additional","affiliation":[{"name":"Surgical Unit, Kasetsart University Veterinary Teaching Hospital, Faculty of Veterinary Medicine, Kasetsart University, 50 Phaholyothin Rd., Lat Yao, Jatujak, Bangkok 10900, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Piyathip","family":"Chuchalermporn","sequence":"additional","affiliation":[{"name":"Radiology Unit, Kasetsart University Veterinary Teaching Hospital, Faculty of Veterinary Medicine, Kasetsart University, 50 Phaholyothin Rd., Lat Yao, Jatujak, Bangkok 10900, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6371-3679","authenticated-orcid":false,"given":"Rungrueang","family":"Yodsheewan","sequence":"additional","affiliation":[{"name":"Department of Pathology, Faculty of Veterinary Medicine, Kasetsart University, 50 Phaholyothin Rd., Lat Yao, Jatujak, Bangkok 10900, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Phudit","family":"Maneesaay","sequence":"additional","affiliation":[{"name":"Department of Pathology, Faculty of Veterinary Medicine, Kasetsart University, 50 Phaholyothin Rd., Lat Yao, Jatujak, Bangkok 10900, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5333-9284","authenticated-orcid":false,"given":"John M.","family":"Cullen","sequence":"additional","affiliation":[{"name":"College of Veterinary Medicine, North Carolina State University, Raleigh, NC 27607, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5107-4577","authenticated-orcid":false,"given":"Jonathan A.","family":"Lidbury","sequence":"additional","affiliation":[{"name":"Gastrointestinal Laboratory, Department of Small Animal Clinical Sciences, School of Veterinary Medicine and Biomedical Sciences, Texas A&M University, College Station, TX 77843, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9373-6169","authenticated-orcid":false,"given":"Panpicha","family":"Sattasathuchana","sequence":"additional","affiliation":[{"name":"Department of Companion Animal Clinical Sciences, Faculty of Veterinary Medicine, Kasetsart University, 50 Phaholyothin Rd., Lat Yao, Jatujak, Bangkok 10900, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"504","DOI":"10.1111\/j.1748-5827.2004.tb00196.x","article-title":"Umbilico-biliary fistula in a dog","volume":"45","author":"Sides","year":"2004","journal-title":"J.
