A rare cause of death in infancy: idiopathic infantile arterial calcification.

The aim of this paper is to report the autopsy findings of an Idiopathic Infantile Arterial Calcification-new-born male and describe its follow-up. Y.R, a 23-days-old male, hasn't any relevant personal past medical or family history. The baby was weighing 3.2 kg at birth. He was breast fed and appeared to be perfectly normal. In the last 24 hours, he presented to the family doctor with vomitis, refuse of feeds without fever or diarrhea. He was diagnosed as having gastroenteritis and was medicated accordingly. A few hours later, he had an hematemese episode associated with facial cyanosis. Death occurred despite cardio-pulmonary resuscitation. Forensic autopsy was required. The macroscopic examination showed a bilateral pleural liquid effusion without any other abnormalities. Microscopic investigation revealed a generalized arterial calcification of all organs. Idiopathic arterial calcification is primarily a disease of infancy. It is characterized pathologically by generalized arterial calcification within the internal elastic lamina, associated with intimal fibrous proliferation. Death occur often in the first sixth months due to heart failure.
