US can be used to perform guided tumor biopsy of the anterior mediastinum. Andersson and associates concluded that US-guided tumor biopsy of the anterior mediastinum is safe, cost-effective, and reliable, as well as a good alternative to traditional biopsy techniques employing mediastinoscopy or thoracotomy. [30]  The authors performed US-guided biopsy of the anterior mediastinum in 23 patients on 28 occasions. US was chosen when CT scanning had shown the tumor to be in contact with the thoracic wall. The procedure was technically successful in all cases, and no complications occurred. In 27 of the 28 occasions, the biopsy diagnosis was identical to the final diagnosis. In 1 patient with a malignant lymphoma, a connective tissue remnant was falsely diagnosed.
