The anterosuperior mediastinal nodule requires surgical treatment. The mediastinum is a fibrous tissue separation behind the middle of the sternum of the body, which contains many important body organs, including the cardiovascular, bronchial, esophageal, aortic arch, superior and inferior vena cava. Clinically, the mediastinum is divided into nine zones, and the anterosuperior mediastinum is one of the systematic subdivisions. Nodules in the anterosuperior mediastinum are mainly from hard masses of thymus and intrathoracic thyroid cysts, but also from conditions such as developmental nerve sheath tumors, cysts and enlarged lymph nodes, with inflammation accounting for a very small proportion. So the anterior superior mediastinum space is particularly narrow, and the growth and development will produce compression after a certain level, leading to pressure on vital organs producing suffocation and diseases affecting cardiovascular activity. So at this time, regardless of whether it is benign or malignant, as long as it produces compression symptoms and affects the normal state of life, active surgical treatment should be taken.
