case_images: CT scan before intervention. (A) Coronal sectional view of enhanced CT of the abdomen with contrast revealed a normal right kidney and a mildly enlarged left kidney with heterogeneous enhancement (black arrows) showing multiple wedge-like hypodense areas involving the renal cortex.. (B) Cross-sectional view of the enhanced CT of the abdomen revealed signs of emphysematous changes (black arrows) and air pockets communicating with the adjacent pelvicalyceal system.

case_images: ICU, and a positive result was obtained. Chest radiography revealed bilateral lung infiltrations. In addition, repeated CT scans showed that the left kidney's EPN was progressing, with the development of two collections with air-fluid: one at the upper pole (4.7x5.1x3.9 cm) and the other mid-kidney with two communicating components (5.5x6.6x8 cm; Figure 1).
case_images: CT scan 2.5 months after discharge. (A) Coronal section of enhanced CT of the abdomen with contrast revealed a left kidney interval decrease in size (white arrow) and resolution of previous hypodense lesions.. (B) Cross-sectional view of enhanced CT of the abdomen revealed improved signs of emphysematous changes (white arrow). There was no air within the small residual collection.
