Is there any consensus of long-term follow-up for incidental anterior mediastinal nodular lesions?

With the recent increase of computed tomography (CT) examination, the detection of mediastinal nodular lesions is becoming more common. According to previous reports, approximately two thirds of mediastinal nodules/masses are benign, and this increases to three fourths among asymptomatic patients (1). About half of these nodules/masses are located in the anterior mediastinum (prevascular compartment) (2-4).
