NEPHROCALCINOSIS AND NEPHROLITHIASIS DUE TO SUBCUTANEOUS FAT NECROSISWITH HYPERCALCEMIA IN 2 FULL-TERM ASPHYXIATED NEONATES - SONOGRAPHIC FINDINGS

Subcutaneous fat necrosis leading to hypercalcemia is rare but well do cumented in asphyxiated neonates. This paper presents two such neonate s in whom sonography revealed the development of nephrocalcinosis and nephrolithiasis. The kidneys had initially been shown to be normal son ographically. In one infant, nephrocalcinosis developed as increasing echogenicity of the medullary pyramids, In the other, increased echoge nicity of the renal cortex of uncertain cause developed together with nephrolithiasis. These sonographic appearances have not been described previously in this entity.
