Ultrasonograms of a calf with severe bronchopneumonia show the development of pulmonary lesions during the course of therapy. Image (a), at admission of the calf, reveals consolidated cranial lobe (CL) with hyperechoic bronchoaerogram (BG). Image (b) for the same calf after 5 days of therapy shows consolidated cranial lobe (CL), bronchoaerogram (BG) and fluid bronchogram (FB). Image (c), after 10 days of therapy, exhibits consolidated lung (CL) and few bronchoaerograms (BG). Image (d), after 20 days of therapy, reveals improvement of pulmonary lesions but lung consolidation (CL) and fluid bronchogram (FB) are still present. Image (e), after 30 days of therapy, shows an obvious improvement in the pulmonary tissue in comparison with previous images but a remnant of fluid bronchogram (FB) is still present.
