Clinical Notes

Normal chest radiographs 2 days prior.


US – Peripheral polygonal hypervascular region in the right hemithorax similar in acoustical architecture to the liver. Note the sharp interface with the adjacent lung.

CT – Coronal reformat shows heterogeneous basilar pulmonary consolidation.


Pleural-based pneumonia is amenable to ultrasound diagnosis. The echotexture of consolidated lung is similar to liver; alveoli filled with inflammatory fluid are hypoechoic and correspond to hepatic parenchyma whereas the air containing bronchioles produce branching echodensities corresponding to the portal triads.
