Introduction: Bronchiolitis obliterans (BO), also known as constrictive bronchiolitis is a fibrosing form of obstructive lung disease that follows a severe insult to the lower respiratory tract. It occurs in a heterogenous group of lesions varying in their etiology, clinical settings and pathologic features but are centered in small conducting airways. Patients and methods: 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. Results: Mosaic attenuation pattern was seen in all patients. Other HRCT findings included bronchiectasis, bronchial wall thickening and centrilobular nodules. Conclusion: 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.
