Over time, the lungs get bigger than usual to make room for new air that's breathed in. The lungs also get stiff and less stretchy, making it harder to push air out.The caudal mediastinum extends from the heart to the diaphragm.

Although the hilar lymph nodes are not visible on a normal chest X-ray, they are of particular importance clinically. Often, hilar enlargement is due to enlargement of these nodes.The other routine view is the lateral radiograph. By convention it is taken at a distance of 6 feet and the left side of the chest is held against the X-ray cassette. Often it is difficult to detect lesions located behind the heart, near the mediastinum, or near the diaphragm on the PA view.

Here are some of the normal mediastinal contours often seen on chest X-rays. These contours are created by difference in density of anatomical structures of the mediastinum and adjacent tissues. Not all of these contours are present on all normal chest X-rays and their visibility depends on technical factors.The cardiac silhouette was enlarged. The Cardio-Thoracic Ratio (CTR) measured 31/50 cm – 62%. A normal ratio should be less than 50%. The lungs and pleural spaces were clear. No evidence of alveolar or interstitial edema. No …Mediastinum Computed tomography (CT) is indispensable in imaging the mediastinum. Although conventional radiographs can show recognizable abnormalities in many patients with mediastinal pathology, radiographs are limited in their sensitivity and ability to delineate the extent of mediastinal abnormalities and the relationship of masses to specific mediastinal structures.The characteristic middle and upper lung zone distribution with central-parahilar predominance and the presence of mediastinal and hilar lymphadenopathy usually lead to the correct diagnosis, obviating the need for lung biopsy. Air-trapping on expiration is another key finding that usually accompanies sarcoidosis [7, 60] (Fig. 34).The retropharyngeal space (RPS) extends from the skull base to the upper mediastinum, and the prevertebral space (PVS) extends from the skull base to the coccyx. Diseases of these spaces are uncommon but can result in significant morbidity.

The trapped air takes up space, so it's harder to get enough fresh air into the lungs. Over time, the lungs get bigger than usual to make room for new air that's breathed in. The lungs also get stiff and less stretchy, making it harder to push air out.Benign teratomas of the mediastinum (mature cystic teratomas or "dermoid" tumors) are rare and account for only 3 to 12% of mediastinal tumors.1, 2 Although these tumors have been described in patients with ages ranging from 7 months to 65 years, most occur in young adults, with an approximately equal incidence in males and females.2-4 No predisposing conditions or associated ....
