Mycoplasma pneumoniae bronchiolitis mimicking asthma in an adult.

Bronchiolitis refers to an inflammatory disease primarily involving the terminal and respiratory bronchioles, and in some cases extending to the adjacent alveolar ducts and alveolar spaces.1,2 Infectious bronchiolitis is well recognized in pediatric patients, but uncommon in adults.3,4 Most pediatric cases are caused by respiratory syncytial virus. In adults, there are occasional reports of Mycoplasma pneumoniae induced bronchiolitis.5,6 Here we report a case of M. pneumoniae bronchiolitis in an adult whose clinical presentation mimicked an acute attack of asthma.
