case_images: Erect abdominal radiograph demonstrating fullness of bilateral renal fossae with obscuration of the psoas outline suggestive of renal masses. Associated mass effect evidenced by inferior displacement of adjacent bowel loops.

case_images: An erect abdominal radiograph demonstrated fullness in bilateral renal fossae with obscuration of the psoas outlines, as shown in Figure 1.
case_images: Sagittal ultrasound image of the right kidney depicting a large perirenal hypoechoic fluid collection with hyperechoic internal echoes compatible with complex fluid. Associated medial displacement and compression of the right kidney. Similar findings were seen on the contralateral side (not shown)

case_images: A subsequent ultrasound was then repeated in the radiology department, showing bilateral subcapsular renal collections with low-level internal echoes (Figure 2).
case_images: (a, b) Contrast-enhanced axial and coronal computed tomography of the abdomen demonstrating large bilateral subcapsular collections (stars) causing compression of the renal parenchyma (arrowheads).
