What is pain just below sternum?
Sternum pain is usually caused by problems with the muscles and bones near the sternum and not the sternum itself.

What are opacities on CXR?
Pulmonary opacification represents the result of a decrease in the ratio of gas to soft tissue (blood, lung parenchyma and stroma) in the lung. When reviewing an area of increased attenuation (opacification) on a chest radiograph or CT it is vital to determine where the opacification is.
What is Retrosternal region?
The retrosternal region (RSS) can be involved by diverse lesions. The RSS is the region behind the sternum and anterior to the ascending aorta. It normally is less than 3 cm deep.
What does hyperinflation look like on chest xray?
Hyperinflation. Chest X-rays of people with COPD may show signs of large lungs, known as hyperinflation. Hyperinflation occurs when the lung tissue has been damaged and loses its elasticity. The lungs may also be trapping the air after each breath.

What is the retrosternal space on a chest radiograph?
Background The retrosternal space (RSS) has been described as one of the two clear spaces seen on a lateral chest radiograph where the lungs meet behind the sternum (the first clear space); the second clear space being the retrocardiac space where the lungs meet behind the heart (Figure 1).
