Plain-English summary
A 4-year-old male neutered domestic shorthair cat was brought to the vet with blood in his urine and difficulty urinating for three months. An ultrasound revealed a large mass in his bladder, which was removed through surgery. After the surgery, the cat received a combination of medications, including cyclophosphamide and thalidomide, for about eight months. Follow-up imaging showed no signs of the cancer returning, and the cat was still doing well nearly two and a half years later.

Abstract
Visceral hemangiosarcomas (HSA) are rare in cats and typically associated with aggressive biologic behavior and poor prognosis. A 4-year-old male neutered domestic shorthair cat was presented with a 3-month history of hematuria and stranguria; ultrasonography identified a large bladder mass. Complete excision was achieved by partial cystectomy. Histopathology and immunohistochemistry for von Willebrand factor confirmed HSA. The cat was treated using adjuvant cyclophosphamide, thalidomide, and meloxicam for 8 months. Abdominal ultrasonography repeated at 2 months and computed tomography repeated at 5 and 19 months after diagnosis showed no evidence of local recurrence or metastasis. The cat was alive at last follow-up (896 days). Although the cat described in this report experienced a more favorable prognosis compared to other visceral HSA locations, additional cases are needed to further understand the biological behavior of bladder HSAs and guide treatment decisions.
