2 case question available
Radiological findings suggest two main differential diagnoses: renal abscess or renal cell carcinoma.
There is no clinical evidence of infection, except for leukocytosis later identified on a blood test. Perinephric inflammatory alterations suggests abscess and it`s extension to perirenal space.
