Summary
A dog diagnosed with urinary tract infections had a fibrosarcoma, a type of cancer, in its bladder. Despite surgery, the cancer spread to the urethra, lungs, and liver, leading to euthanasia.
Area of Science:
- Veterinary Pathology
- Canine Oncology
Background:
- Recurrent urinary tract infections (UTIs) in dogs can indicate underlying complex conditions.
- Diagnostic imaging plays a crucial role in differentiating UTIs from other pathologies.
Observation:
- A 14-month-old dog presented with a 7-month history of recurrent UTIs.
- Sonography revealed a focal, multilobulated thickening of the urinary bladder wall, originating near the ureteral openings.
- The urethra also showed uniform thickening, suggesting urethritis or neoplastic infiltration.
Findings:
- Histopathological examination confirmed a fibrosarcoma in the lamina propria of the urinary bladder wall.
- Despite initial surgical excision, the tumor recurred, evidenced by persistent hematuria.
- Postmortem examination revealed urethral infiltration and metastasis to the lungs and liver.
Implications:
- Fibrosarcoma should be considered in cases of recurrent UTIs with focal bladder wall abnormalities in dogs.
- Early and accurate diagnosis is critical, as fibrosarcomas can be aggressive and metastasize.
- This case highlights the importance of thorough postmortem examination for comprehensive understanding of tumor behavior and spread.
