Obliterative bronchiolitis due to Mycoplasma pneumoniae infection in a child

A 6-year-old girl presented with Mycoplasma pneumoniae involving the right upper and lower lobes. She made a slow but complete recovery with resolution of the radiological changes. She re-presented 5 years later with a productive cough, recurrent wheezing and physical and radiological signs suggestive of obliterative bronchiolitis. This diagnosis was confirmed by ventilation - perfusion (V/Q) lung scan, and bronchography. The case highlights the value of V/Q scanning in the diagnosis of obliterative bronchiolitis and confirms the previous reports that mycoplasma infections are not always benign.
