case_images: B mode sagittal (left) and transverse (right) imaging planes of right kidney from case 1. Note the thin-walled, anechoic 5 cm simple cyst at the inferior pole of the kidney with posterior acoustic enhancement.

case_images: The attending nephrologist sent the nephrology fellow for a referral study which again demonstrated an empty right renal fossa (Figure 3) and normal left kidney.
case_images: Oblique imaging plane of right iliac fossa from case 2 demonstrating the presence of renal parenchyma in this ectopic location.
