Hyperattenuating pulmonary abnormalities refer to lung parenchymal opacities/lesions that are generally higher attenuation on CT than most soft tissues. An exact definition is usually not provided 1-3, while some authors focus on abnormalities that are as subjectively opaque as bony structures 4. These findings can result from a variety of processes and have varied radiographic appearances. It is easiest, for the purposes of radiology, to divide them by morphology:
- hyperattenuating linear or reticular opacities
- hyperattenuating pulmonary nodules
- hyperattenuating pulmonary mass
- hyperattenuating consolidation
