Radiologic findings in primary hyperoxaluria

Abstract

Six out of seven patients with primary hyperoxaluria showed various degrees of oxalosis. The radiographic manifestations differ between patients younger than 15 years and those older than 45 years. The mild manifestations in children, only urolithiasis, can be explained by the, as yet, unimpaired renal function. The renal function in the older patients, with extensive pathologic changes like nephrocalcinosis, urolithiasis, soft-tissue calcification, and osseous changes, is very poor. The findings of extensive softtissue calcification and the bony changes are not in complete agreement with those in the literature.
