The study included 20 patients 14 females and 6 males, mean age range 7-64 years (average of 39.25 years) with a variety of chest symptoms on whom HRCT was performed.
Mosaic attenuation pattern was seen in all patients. Other HRCT findings included bronchiectasis, bronchial wall thickening and centrilobular nodules.
High-resolution CT is currently superior as an imaging modality in diagnosis of bronchiolitis obliterans, however, diagnosis of BO requires exclusion of other causes of chronic airway obstruction.
