Kidney cysts in a capuchin monkey (Sapajus libidinosus) – case report
Cystic lesions in the renal parenchyma can be attributed to several types of pathologic conditions, such as acquired renal cysts and polycystic kidney disease. Some clinical criteria are used to distinguish between these two diseases. Ultrasonography aids in the characterization of cystic lesions in the abdominal organs, allowing the diagnosis of these diseases. We hereby report the case of a young adult female capuchin monkey (Sapajus libidinosus) submitted to clinical and sonographic examination in order to evaluate its health prior to reintroducing the animal in nature. Physical examination did not reveal any type of alteration. However, the ultrasonogram disclosed the presence of some renal cysts in the right kidney, as well as a hepatic cyst. There are very few reports in the literature of the presence of renal cysts in primates.
