Plain-English summary
A group of older mixed breed cats, averaging 16 years old, were found to have fluid-filled sacs around their kidneys called perinephric pseudocysts (PNPs) during examinations for chronic kidney disease. These sacs were often mistaken for enlarged kidneys and were commonly associated with urinary tract infections. Diagnosis was confirmed through ultrasound and fine-needle aspiration, and treatment involved either surgical removal of the pseudocysts or draining them with ultrasound guidance. Cats with PNPs generally have a good outlook if their kidney disease isn't too advanced and there are no other serious health issues.

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.
