[Histo-radiologic correlations in patients with primary hyperoxaluria]

The use of new dialythic technics has increased the survival times for patients with primary hyperoxaluria. From here the possibility of visualizing X-rays signs specific of oxalosis besides the typical bone lesions of hyperparathyroidism secondary to chronic renal failure. Recent hysto-pathological studies allowed to correlate such radiological findings to a new pathogenetical mechanism that would be responsible of the bone lesion specific for oxalosis and that might be caused by the presence of reabsorption cavities made up by macrophagic cells fagocyting cristals.
