抄録

A 12-year-old castrated male Shih Tzu presented to the hospital with hematuria that had lasted for about 1 month. Abdominal ultrasonography and computed tomography revealed hydronephrosis due to a mass in the left urinary tract and a left adrenal tumor. Adrenal glandectomy and nephroureterectomy were performed. The histopathological examination revealed concurrent adrenocortical adenoma and pheochromocytoma in the same adrenal gland. A fibroepithelial polyp developed in the left ureter, with subsequent hydronephrosis. There was no recurrence or metastasis of adrenocortical adenoma, pheochromocytoma or the ureteral fibroepithelial polyp after surgical removal.
