Idiopathic infantile arterial calcification: Unusual features

摘要

Idiopathic infantile arterial calcification (IIAC) is a rare disease of unknown etiology, which causes wide-spread arterial calcification and usually leads to early death from coronary arterial occlusion. Periarticular calcification has been reported in some cases. Two new cases are reported. In addition to the usual features of the disease, one was found to have ear-lobe calcification and the other an aortic aneurysm and coarctation of the aorta. Therapy with diphosphonate was apparently successful in one patient.
