anterior mediastinal germ cell tumours

A diagnostic

approach to the mediastinal masses. Non-seminomatous malignant germ cell tumour of the anterior mediastinum in a 25-year-old man with chest pain and high serum level of α-fetoprotein at admission (25.396 ng/ml). Frontal chest radiograph shows a central mass (*). The descending aorta is clearly seen (arrows), indicating that the mass is not within the posterior mediastinum. Multiple nodules in bilateral pulmonary field are also observed. A contrast-enhanced CT scan confirms a mass of low attenuation (*) in the anterior mediastinum that compresses the pulmonary artery. Bilateral lung metastasis (arrowheads) and hilar and subcarinal lymphadenopathy is identified (open arrows)
