Idiopathic isolated laryngotracheobronchial cartilage calcification in a child.

Laryngeal, tracheal, and bronchial cartilage calcification is quite rare in children. It was reported to occur in congenital cardiovascular diseases, Keutel syndrome, chondroplasia punctata, warfarin embryopathy, and warfarin sodium therapy. It can occur idiopathically as well. Laryngotracheobronchial cartilage calcification is demonstrated in this report by chest radiography and multiplanar three-dimensional CT examination in a 2.5-year-old boy with nonspecific cough.
