Ultrasound B-mode, consolidations. A) Bacterial pneumonia and atelectasis. Note branching air bronchograms (white arrowheads), effusion (asterisk), consolidation (hash) and artifact from air between probe and skin (white arrow). B) Aspiration pneumonia. Note consolidation (hash) with air bronchograms (white arrowheads), no effusion. C) Obstructive atelectasis. Note nodule (asterisk) at hilum and inhomogenous infiltrate (hash) with calcifications. Rest of atelectatic lung is relatively homogenous. Air bronchograms are absent. D) Combined obstructive atelectasis and neoplastic infiltration. Note that lung is relatively homogenous (hash). There are single air bronchograms (white arrowheads) and small effusion (asterisk)
