Risks include pneumothorax and internal bleeding. (21 Mar 1998) |

| pleural reaction | Thickening of the pleural stripe on chest radiographs, representing pleuritis, pleural effusion, or pleural fibrosis. (05 Mar 2000) |
| pleural recesses | Three recesses of the pleural cavity, one behind the sternum and costal cartilages (costomediastinal recess), one between the diaphragm and chest wall (costodiaphragmatic recess), and one between the diaphragm and mediastinum (phrenicomediastinal recess).
