WebBy definition, mosaic attenuation is a CT pattern in which areas of differing attenuation are found diffusely distributed throughout the lung parenchyma. These areas have well-defined borders, which correspond to the borders of the secondary pulmonary lobules or to a set of them. An MAP may be due to vascular diseases, small airways diseases ... WebMosaic attenuation. Mosaic attenuation of lung parenchyma based on multifocal hypoperfusion or hypoventilation can mimic ground-glass opacities, but is fundamentally distinct. Here, it is the low density pulmonary parenchyma that is abnormal. It is caused by bronchopathy with hypoventilation and secondary hypoxic vasoconstriction.
