Idiopathic arterial calcification of infancy.

Idiopathic arterial calcification of infancy is an uncommon disease of unknown etiology, characterized by calcification along the internal elastic membrane and intimal proliferation of almost all the arteries of the body. When the diagnosis is made premortem, it is usually done by radiographic demonstration of arterial calcification. Because of its edge enhancement effect, xeroradiography should be useful in detecting the soft tissue calcifications of this disease.
