High-resolution CT findings in patients with severe acute respiratory syndrome: a pattern-based approach

AJR Am J Roentgenol. 2004 Jan;182(1):49-56. doi: 10.2214/ajr.182.1.1820049.


Objective: We retrospectively reviewed high-resolution CT (HRCT) examinations of the lungs performed in 27 confirmed cases of severe acute respiratory syndrome (SARS). The HRCT findings at different phases of the illness were analyzed.

Conclusion: A defined pattern of HRCT findings is observed in different phases of SARS, which is characterized by focal ground-glass and crazy paving patterns in a scattered distribution at presentation, followed by development of interstitial thickening, consolidation, pleural reaction, and scarring. Spontaneous pneumomediastinum is a distinct complication during the course of the illness.
