The differential diagnosis and the treatment approach to a mediastinal mass are dictated by its location (anterior, middle, or posterior mediastinum). A CT scan will help identify the location as well as the characteristics of the mass. All symptomatic masses of the mediastinum warrant resection. Posterior masses are most commonly neurogenic in origin, whereas middle masses are typically cystic in nature. Anterior masses (4Ts) require a more extensive workup and a disease-specific treatment.
