Thirty-nine consecutive patients with consolidated lung confirmed
radiologically underwent sonography, and their sonograms were compared with
results for 100 healthy subjects. The hyperechoic line of normal aerated
lung and its air artifacts showed respiratory motions ("gliding sign," n =
100). Patients with pneumonia demonstrated distinct sonographic patterns.
Strong linear echoes with characteristic air artifacts (air bronchogram)
and anechoic tubular structures (fluid bronchogram) were visualized in 36
of 39 patients (92.30%). The superficial lung showed a homogeneous
hypoechoic band termed "superficial fluid alveolograms" (n = 39) with
respiratory motions in 35 of 39 patients. We conclude that sonography can
evaluate pulmonary consolidation and may provide additional
roentgenographic information, especially when fluid bronchograms are
visualized.
