0 a structure that divides a body part in the centre:
a mediastinal tumour
1 the area of the chest that contains the heart and other organs and tissues
Extralobar sequestrations can occur anywhere in the mediastinum or even intraabdominally.
Among the 24 evaluable patients, there were no instances of tumour relapse in the upper mediastinum.
At postmortem examination, there was found to be a false aneurysm in the mediastinum due to rupture of the aneurysmal pulmonary trunk.
The tumour was also bulging into the posterior mediastinum, causing compression of the airways.
Another set of imaging studies continued to reveal persistent adenopathy in the left axilla, left internal mammary node region, and the anterior mediastinum.
They involve the neck and can extend into the mediastinum.
Exploration of the mediastinum revealed a large mass covered by pericardium.
The security is provided by the ability expeditiously to perform a full sternotomy, and yet have complete access to the entire mediastinum if necessary.
