B-lines ultrasound pneumonia
WebSubpleural consolidation, recognized as a sign of viral pneumonia in association with variation of B-lines, were reported only in a few cases (between 1.5% and 66.6%) in the lung ultrasound exam in the target group [17,18,19,20,21,22]. No pleural effusion or pneumothorax was reported. WebB-lines are shining vertical lines perpendicular to the pleural line that extend from it to the edge of the screen, erasing the A-lines [ 3 ]. Lung ultrasound (LUS) is an attractive diagnostic test because COVID-19 disease involves the periphery of the lung and because it is a bedside tool with good diagnostic accuracy.
