[Primary space-occupying lesions in the mediastinum]

Authors report four cases of mediastinal tumors. X-rays, CT scan, bronchial endoscopy, angiography and mediastinal endoscopy can be useful to diagnose this kind of neoplasms. Surgical treatment and, further, radio or chemotherapy are used in case of mediastinal neoplastic lesions. Unfortunately, lifetime longer than five years is observed just in 50% of the patients.
