The defects in the parenchyma occur at the junction of the renunculi. Junctional parenchymal defect jpd is a triangular or linear hyperechoic structure in the anterosuperior or posteroinferior surface of the kidney. Junctional parenchymal defects in renal imaging are a normal variant which results from the incomplete embryonic fusion of renunculi.
The junctional defect is a prominent v shaped defect in the cortical surface that marks the junction of lobes from the upper pole with lobes of the lower pole.
In order to differentiate them from pathologic conditions one must identify their characteristic location and demonstrate continuity with the renal sinus.
