Cystic multiloculated mass involving the renal parenchyma in the middle and lower third of the left kidney. Intense inflammation in perirenal fat.
Case Discussion
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 changes are more suggestive of an abscess.
The case was confirmed and treated as an abscess.
This would lend itself to a straightforward ultrasound-guided percutaneous abscess drainage.
