Lung Point Case 3

45 year old male presents with left sided chest pain after scuba diving. What does the ultrasound show?

Reveal Answer

This clip shows a very small anterior pneumothorax

Look at the bright pleural line lying horizontally just deep to the two ribs. Follow the pleural line to the right, and cardiac and mediastinal movement can be seen. Follow the pleural line to the left, and lung sliding and a lung point are seen.

Between the normal lung sliding and the repetitive cardiac movement is an area of still parietal pleura. Here lung sliding is lost, and deeper A-lines can be briefly demonstrated, but are interrupted repetitively by intervening cardiac pulsations.

A small pneumothorax is present below the transducer, but it is hidden briefly every cardiac cycle as the heart pushes against the parietal pleural surface displacing the pneumothorax out of view.
