was changed:
A pneumothorax does not display classical signs when a patient is positioned supine for a chest radiograph. Instead, the pneumothorax may be demonstrated by looking for the following signs:
- relative lucency of the involved hemithorax
- deep, sometimes tongue-like, costophrenic sulcus: deep sulcus sign 2
- increased sharpness of the adjacent mediastinal margin and diaphragm
- increased sharpness of the cardiac borders
- visualisation of the anterior costophrenic sulcus: double diaphragm sign 3
- visualisation of the inferior edge of the collapsed lung above the diaphragm
- depression of the ipsilateral hemidiaphragm
- lumpy appearance of the cardiac contour representing change in shape of the pericardial fat: pericardial fat tag sign
