There is a low density cystic structure in the anterior aspect of the right kidney At the level where it bulges beyond the confines of the kidney there are soft tissue changes in the perinephric fat and extending to the properitoneal fat.  A small enhancing medial rim may be part of the abscess or part of the kidney.
