A mediastinal tumor is a tumor in the mediastinum, the cavity that separates the lungs from the rest of the chest. It contains the heart , esophagus , trachea , thymus , and aorta . The most common mediastinal masses are thymoma (20% of mediastinal tumors), usually found in the anterior mediastinum, followed by neurogenic Timor (15–20% ...
Mitral annular calcification (MAC) is a multifactorial chronic degenerative process in which calcium with lipid is deposited in the annular fibrosa ring of the heart's mitral valve. MAC was first discovered and described in 1908 by M. Bonninger in the journal Deutsche Medizinische Wochenschrift . [ 1 ]
This PA chest radiograph demonstrates an abnormal contour in the right hilar region, with visualization of the pulmonary vessels through the mass (the hilar overlay sign) indicating its posterior mediastinal location. On resection this was found to be a benign solitary fibrous tumor of the pleura.
Mediastinal shift is an abnormal movement of the mediastinal structures toward one side of the chest cavity. A shift indicates a severe imbalance of pressures inside the chest. [ 1 ] Mediastinal shifts are generally caused by increased lung volume, decreased lung volume, or abnormalities in the pleural space.
T2b: Primary tumor is >5 and ≤7 cm in greatest dimension. T3 size: Primary tumor is >7 cm in greatest dimension; T3 inv: Primary tumor invades the chest wall, diaphragm, phrenic nerve, mediastinal pleura, or pericardium; T3 centr: Primary tumor is <2 cm to the carina or there is atelectasis of the entire lung;
One of the principal causes of arterial stiffening with age is vascular calcification. Vascular calcification is the deposition of mineral in the form of calcium phosphate salts in the smooth muscle-rich medial layer of large arteries including the aorta. DNA damage, especially oxidative DNA damage, causes accelerated vascular calcification. [11]
CT scan of the chest showing bilateral lymphadenopathy in the mediastinum due to sarcoidosis. Bilateral hilar lymphadenopathy is a bilateral enlargement of the lymph nodes of pulmonary hila. It is a radiographic term for the enlargement of mediastinal lymph nodes and is most commonly identified by a chest x-ray.
