Junctional parenchymal defects in renal imaging are a normal variant, which results from the incomplete embryonic fusion of renunculi.

Radiographic features

Ultrasound

It can be seen as a triangular echogenic cortical defect, frequently seen in upper lobe parenchyma. The defect is the extension of sinus fat into the cortex, usually at the border of the upper pole and interpolar region of the kidney.
