Abstract

Introduction: An infectious bronchiolitis, making an obstruction of small airways in the children less than 2 years old, is a very rare disorder in adults. We evaluated the clinical manifestations of 5 adult patients with transient airway obstruction and dyspnea which resemble the manifestations of infectious bronchiolitis in the children.
Methods and results: Their median age was 65 years old. All of them had acute onset of a coughing, dypnea, and wheezing. The chest P-A showed ill-defined nodules and haziness, the findings of HRCT were poorly defined centrilobular nodules, branching linear opacity, and air trapping suggesting the lesions of small airway. They denied a previous history of bronchial asthma or any obstructive airway diseases and PFT showed the PC20 were more than 25 mg/mL in methacholine challenge test and no bronchodilator responses in all patients. Their symptoms had persisted for 7-14 days with antibiotics and bronchodilator. The findings of chest P-A and HRCT were completely normalized at 5-9 months later and nobody showed any recurrence.
Conclusion: An infectious bronchiolitis should be considered in the differential diagnosis in adult patients showing acute onset of cough, dyspnea and wheezing.
