Postinfectious bronchiolitis obliterans: An uncommon complication of severe viral pneumonia in an infant: A case report

Postinfectious bronchiolitis obliterans (PIBO) is a rare, chronic form of obstructive lung disease characterized by obliteration of small airways leading to clinical and radiological manifestations of smaller airway obstruction. Adenovirus is the most common viral pathogen associated with PIBO in the pediatric population. We report a 7-month-old male who developed PIBO following severe viral pneumonia to highlight the significance of early diagnosis, challenges faced during the clinical course, treatment of acute exacerbations, and long-term care.
