From: Electrocardiographic manifestations in a large right-sided pneumothorax
Initial chest radiographs and computed tomography scans (a, c, and d: during inspiration, b: during expiration). a Chest radiographs reveal a huge right-sided pneumothorax during inspiration. The absence of lung markings peripheral to the thin white visceral pleural line (white arrowheads) can be noted. b During expiration, increased intercostal space and a pronounced leftward mediastinal shift (arrows) are recognized. The hemidiaphragm on the right side remains quite depressed. c, d Chest computed tomography scans reveal a huge right-sided pneumothorax during inspiration. The extracardiac compression of the right atrial free wall result in a straightened cardiac border (yellow arrowheads). RA right atrium, RV right ventricle
