Other conditions of the mediastinum
Many of  the primary tumours such as neurogenic tumours and germ cell tumours can present as cysts or have a cystic quality . In addition, the mediastinum can contain other cysts, often with an embryological aetiology . Thymic, pericardial, bronchogenic and foregut cysts can all present asymptom - atically or with local compression ( Figure 60.26 ). Surgical excision is recommended if  the diagnosis is unclear or the patient has symptoms.
