Abstract
Computed tomography was done on 4 patients suspected of having an intrarenal or perirenal abscess based on clinical grounds and an abnormal excretory urogram. Intrarenal abscesses with perinephric extension were demonstrated in 3 patients and a solitary perinephric abscess was demonstrated in 1. Computed tomography is a valuable tool in the diagnostic study of suspected intrarenal and perirenal abscesses because both the primary abscess and its possible extrarenal extension can be shown.
