Case summary A 1-year-old, neutered male domestic shorthair cat with a several-day history of anorexia and lethargy presented to The Ohio State University Veterinary Medical Center. On physical examination, a mass-like lesion was palpated in the mid-abdomen. Abdominal radiographs, ultrasound and contrast-enhanced CT revealed a mass-like lesion associated with the right kidney. Unilateral nephrectomy with removal of the mass in its entirety was performed as the sole treatment modality, and histopathology revealed a renal nephroblastoma. Postoperatively, the cat was re-evaluated every 3–6 months. The cat continues to do well more than 3 years since diagnosis, which is longer than most published cases. Relevance and novel information This report aims to describe a case of feline nephroblastoma managed solely by surgical treatment, with an unexpectedly long survival time.
