Summary
A rare case of spontaneous external biliary fistula in a dog is presented, originating from a dilated bile duct and presenting as a draining tract. Surgical removal of the affected liver lobe and fistula led to a full recovery, highlighting the importance of considering this condition in similar canine presentations.
Area of Science:
- Veterinary Medicine
- Comparative Pathology
- Surgical Oncology
Background:
- A 10-year-old female dog presented with a chronic subcutaneous mass and draining tract on its thoracic body wall.
- Diagnostic imaging, including computed tomography and fistulography, confirmed a fistulous tract and an associated liver lesion.
Observation:
- Surgical exploration revealed the tract extended into the thoracic cavity, diaphragm, and liver, terminating in a cystic lesion.
- Histological examination identified the liver lesion as a fibrotic, dilated bile duct lined with biliary epithelium.
Findings:
- A diagnosis of spontaneous external biliary fistula was established based on the surgical and histological findings.
- The dog underwent successful surgical resection of the affected liver lobe and fistula.
Implications:
- This case represents the first reported instance of spontaneous external biliary fistula in a dog.
- The condition should be considered in canine patients presenting with similar clinical signs, and diagnostic imaging is crucial for diagnosis and surgical planning.
