Figure 2 Basic lung ultrasound findings. A: Normal lung ultrasound demonstrating A-lines (horizontal hyperechoic artifacts); B: Pleural effusion (“a”) appearing as an anechoic area above the liver. Arrow points to atelectatic lung; C: B-lines-vertical hyperechoic artifacts emerging from the pleural line indicative of interstitial thickening (typically from fluid); D: Interstitial pneumonia with confluent B-lines and an irregular pleural line. Arrow points to subpleural consolidation.
