RESUMO
A 16-year-old, neutered male, domestic short hair cat had abdominal distension and systemic hypertension. Radiography, ultrasonography, excretory urography, and renal scintigraphy were performed to establish the diagnosis and implement appropriate treatment. Bilateral perirenal pseudocysts were confirmed surgically and histopathologically. Following bilateral renal capsulectomy, systemic hypertension decreased and global glomerular filtration rate improved to normal limits. Multiple imaging modalities helped establish the diagnosis and guided implementation of appropriate treatment.

The macroscopic and microscopic features of a uriniferous perirenal pseudocyst in a castrated male 12-year-old American Domestic Short Hair cat are characterized. The development in humans and animals of a perirenal pseudocyst due to the accumulation of urine, lymph, or blood is discussed. In the presented case, microscopic evidence suggests that the pseudocyst developed following formation of a split in the kidney capsule. Emphasis is placed on the development of uriniferous pseudocysts and three proposed criteria for their development: trauma, abnormal openings that allow extravasation of urine, or urethral obstruction.
