The polycystic kidney disease (PKD) is an illness of major importance for feline clinics since it is the most important hereditary decease of felines all over the world. It occurs especially in Persian and correlated breeds. This work aims at describing images of ultrasonography of extra-kidney lesions in PKD cats. A 15-year-old Persian feline, male, showed a report of polydipsia and polyuria for 2 months and weight loss. The following exams were carried out: physical, hemogram, biochemical profile, analysis of urine, and the relation of protein/creatine in the urine. Although alterations related to the physical exam and hemogram were not observed, in the biochemical profile, it was observed the following: 3,7 mg/dl of creatine, 113 mg/dl of urine, 3,40 mg/dl of phosphorus and 73 UL of ALT; also in the urine analysis the following were observed: pale colour, 1.020 of density, pH 5, +++ leukocytes, rare bacterial and transitional cells. In order to complete the exams, the animal was referred to an evaluation by ultrasonography aiming at visualizing abnormalities in the abdominal tissue. The exam showed cyst-like images in the kidney structure (right and left side), in the liver and in the pancreas. Therefore, it is possible to conclude that the PKD can affect other abdominal organs as it is usually observed in the liver tissue, but not as much in the animal pancreas. A detailed evaluation by ultrasonography of the abdominal cavity in order to diagnose less severe lesions of this disease should be carried out.
