[Bilateral nephrocalcinosis during the course of a Butler-Albright syndrome, explored by ultrasonography. A case report (author's transl)].

Ultrasonography was employed to explore bilateral nephrocalcinosis in a patient with chronic renal tubular acidosis. Ultrasonographic findings in this affection include multiple intraparenchymatous dense echos in the papillomedullary region with a posterior acoustic shadow cone. Technical artefacts employed to establish diagnosis are discussed.
