[Primary oxalosis in childhood. Plain film findings during the course of the disease (author's transl)].

The radiological changes in the kidneys and skeleton in primary oxalosis in a patient are described. Crystalline calcium oxalate deposits, which are a secondary phenomenon, are responsible for the findings, which are of great significance both functionally and prognostically. Hyperoxalaemia is due to an enzyme defect, which leads to hyperoxaluria; this causes a reduction in renal function and can lead to rapid progression of the condition.
