| Abstract: | Clinical diagnosis of renal tumors in the horse has been difficult because the traditional diagnostic techniques are inadequate. Because of this shortcoming, early publications rarely reported antemortem diagnosis of primary renal tumors. Conventional radiographic techniques cannot effectively outline kidneys in the adult horse. With the advent of ultrasonography, a new dimension to the evaluation of the large-animal kidney has been introduced. Percutaneous diagnostic ultrasonography provides a noninvasive method of examining both kidneys. This report describes a 15 year-old Tennessee Walking Horse mare presented for evaluation of a mass in the sublumbar region, polyuria and polydipsia. Clinical examination and laboratory test results suggested intra-abdominal neoplasia. Two-dimensional ultrasonographic images of the mass were consistent with renal neoplasia. Histologic diagnosis of ultrasound-guided renal biopsy was renal tubular cell carcinoma. |
