High-resolution CT appearance of XXXX .

@entity9758 @entity1 @entity854
OBJECTIVE: The purpose of this study was to define the @entity854 and to assess the contribution of high-resolution CT (HRCT) in the evaluation of @entity9758 involving the lung parenchyma. MATERIALS AND METHODS: The authors retrospectively reviewed HRCT scans of 11 @entity1 with microbiologically or clinically proved @entity9758 . RESULTS: In 10 @entity1 , the most characteristic HRCT finding of @entity9758 was the presence of small nodules uniformly distributed throughout both lungs. The profusion of nodules was numerous in all 10 @entity1 . High-resolution CT scans showed both sharply and poorly defined, small nodules varying in sizes from 1 to 2 mm (n = 6), 1 to 3 mm (n = 2), and 1 to 4 mm (n = 2) in diameter. These nodules had a diffuse random distribution in the secondary lobule in all 10 @entity1 . In 1 of the 10 @entity1 with small nodules on HRCT, chest radiography had shown no evidence of miliary nodules in the lung. In addition to nodules, HRCT showed diffuse or localized reticular opacities superimposed on nodules in five @entity1 , especially in the lower lung zones. In 1 of all 11 @entity1 , ground-glass attenuation was the predominant abnormality seen on HRCT. CONCLUSION: We believe that in the appropriate clinical situation, @entity9758 may be suggested on HRCT. Moreover, in cases with no evidence of miliary nodules on the chest radiograph, HRCT scan may depict miliary nodules in the lung parenchyma.
