Abstract
To evaluate the high-resolution computed tomography (HRCT) findings in 53 patients with exogenous lipoid pneumonia and to compare the imaging features of adults and children. The study included 35 children and 18 adults. Statistical comparisons of findings in the 2 age groups were performed using either Pearson chi2 or Fisher exact test, as appropriate, at 5% significance level. The main HRCT findings included air-space consolidation, ground glass attenuation, air-space nodules, and crazy-paving pattern. Abnormalities predominated in the posterior regions of the right lung. The right lower lobe was most likely to show severe involvement. The presence of air-space consolidation, the involvement of upper right lobe, and the central and posterior distribution of the lesions were more common in children, whereas the crazy-paving pattern and random localization were significantly more frequent in adults. The other findings were not different between the 2 groups.
