[Radiological signs of type I primary hyperoxaluria].
The authors report the radiological signs observed in 14 patients between the ages of 3 months and 16 years, suffering from type I primary hyperoxaluria. Four of these patients were being treated conservatively for renal failure and ten had reached end-stage renal failure. Stones were demonstrated in 9 patients. Nephrocalcinosis was present on the plain abdominal x-ray in 6 patients before dialysis, and in all patients dialysed for more than 3 months. Bone signs characteristic of type I primary hyperoxaluria were only observed in children with end-stage renal failure. Metaphyseal dense bands were revealed in 5 patients. Metaphyseal clear bands, observed in 4 patients, occurred later and appeared to replace dense bands which moved towards the diaphysis. The other signs detected were osteosclerosis of the vertebrae and ilium (4 patients) and epiphyseal subchondral clear bands (one patient).
