Renal Cortical Necrosis


US – Punctate and linear cortical calcifications; otherwise preserved renal echogenicity.


Renal cortical necrosis, renal medullary necrosis, and combined renal cortical-medullary necrosis result from renal ischemia without vascular occlusion. Renal hypoperfusion and ischemic injury in infants have been ascribed to massive blood loss, hemolytic disease, septicemia, and severe hypoxemia. There is no predilection of the cortex compared to the medulla or combined cortex and medulla for ischemia. Prematurity, respiratory distress syndrome, bleeding diathesis, and congenital heart disease may be potentiative factors for developing renal ischemia.
