The major teaching points of this exhibit are: 1. Sonographic artifacts arising from the pleural line and dynamic signs can be used to diagnose pneumothorax, pulmonary edema, pneumonia and other acute pathologies that abut pleural surface 2. Sonographic signs of pneumothorax include loss of lung sliding, multiple A lines and lung point 3. Sonographic B lines, when diffuse and bilateral, are likely caused by pulmonary edema in an acute setting. When they are focal, localized interstitial process is considered. 4. Acute rib, sternal and clavicular fractures are shown as a cortical step off  with localized tenderness on sonography.

Utility of thoracic sonography in emergency setting. Sonographic techniques. Normal sonographic appearances: lung sliding and artifacts (A line, comet tails), bone surface Abnormal sonographic appearances: lung point and artifacts (B line, E line). Review of imaging findings - Thoracic wall (rib fracture, sternal fracture, clavicle fracture, chest wall hematoma). - Pleura (pleural effusion, hemothorax, empyema, pneumothorax). - Lungs (pulmonary infarction, pneumonia, atelectasis, pulmonary contusion). - Heart and mediastinum (pericardial effusion, pulmonary edema). Mimics and pitfalls Summary.
