EXPRESS: Computed Tomography Findings and Outcome following Nephrectomy as Sole Therapy for Renal Nephroblastoma in a Cat

Case summary: A one-year-old neutered male Domestic Shorthair (DSH) 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 computed tomography 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. Post-operatively, the cat was re-evaluated every 3 to 6 months. The cat continues to do well at greater than 3 years from 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.
