Abstract

Perinephric pseudocysts (PNPs) are fluid-filled fibrous sacs that surround the kidney and are not lined by an epithelium. In cats, PNPs are idiopathic, but they usually occur in association with chronic renal failure (CRF). Thirteen cats with PNPs were examined. PNPs occurred in mixed breed cats of either sex with a median age of 16 years. The PNP was palpable on physical examination and usually was interpreted as renomegaly. Clinicopathologic findings reflected CRF, and urinary tract infection was common. Rarely, a primary renal disease was diagnosed concurrent with PNPs and CRF. Diagnosis of PNPs was made by ultrasound examination and fine-needle aspiration, and treatment was by surgical removal of the PNP or ultrasound-guided drainage. Compared to previous reports of PNPs, this series of cats tended to be older and no sex predilection was found, but other findings were similar to those in the literature. Cats with PNPs may have a favorable prognosis if CRF is not severe and no other concurrent diseases are present.
