title: Two unusual cases of nephrocalcinosis in infancy.
abstract: Nephrocalcinosis is uncommon in childhood, the main causes are renal tubular acidosis, hyperparathyroidism and medullary sponge kidney. It is also seen where there is hypercalcaemia or hypercalciuria of any aetiology; We report nephrocalcinosis in an 18-month-old infant with metaphyseal chondrodysplasia type Jansen and also in a neonate with McCune Albright syndrome who displayed atypical skeletal appearances and had multiple ovarian cysts.
