Clinical features
- Leading cause of lower respiratory tract infection in infants and young children (eMedicine)
- Often in children under 2 years old; may cause death in infants 1 - 6 months
- Usually self limited infection in older children
- Infects respiratory epithelium, leading to acute inflammatory response with epithelial sloughing and diffuse alveolar damage in severe cases
Microscopic (histologic) description
- Prominent airway obstruction (Mod Pathol 2007;20:108)
- Giant cells with inconspicuous, round, pink intracytoplasmic inclusions and acute inflammation
- Affects small bronchiole epithelium, type 1 and 2 pneumocytes, not basal cells
- Inflammation centered on bronchial and pulmonary arterioles, due to monocytes, T cells, neutrophils
