Patient Data

Patchy, segmental/wedge-shaped areas of increased and decreased attenuation throughout both lungs. Few areas mild bronchial wall thickening. Normal caliber vasculature. 

Case Discussion

This case nicely demonstrates typical findings of mosaic attenuation, with areas of segmental lucency and relative increased attenuation throughout all lobes. There is are a few areas of mild bronchial wall thickening. Therefore, the findings are favored to be related to small airway/air trapping rather than small vessel (or parenchymal) disease.
