Abstract Fifty-one patients aged 1 year to 56 years with metabolic bone disease underwent renal ultrasound. Medullary nephrocalcinosis was found in nine of 24 patients with X-linked hypophosphatemic rickets and is considered to be iatrogenic, related to vitamin D therapy. Another three in this group of 24 with both medullary and cortical increased renal echogenicity had suffered from repeated episodes of vitamin D intoxication and had secondary hyperparathyroidism. Nephrocalcinosis was less frequent in patients with treated vitamin D-dependent rickets or hypophosphatemic bone disease where generally smaller doses of vitamin D are given. Patients with pseudohypoparathyroidism, on small doses of vitamin D, had a normal renal ultrasound. In cystinosis and Fanconi's syndrome, the kidneys are small, echodense (both the cortex and medulla) with a tendency to cyst formation.
