Primary mediastinal germ-cell tumors are rare neoplasms that usually occur in young men. Computed tomographic (CT) scans in four patients demonstrated large anterior mediastinal masses obliterating fat planes and extending inferiorly along the left mediastinal border. Nonseminomatous tumors contained areas of near-water density (cyst formation and/or necrosis) as well as soft-tissue density. Although CT features may suggest the diagnosis before histologic confirmation, the most important roles of CT are evaluation of extent of disease and monitoring response to therapy.
原发性纵隔生殖细胞肿瘤是罕见的肿瘤，通常发生于年轻男性。4例患者的计算机断层扫描（CT）显示前纵隔有巨大肿块，脂肪平面消失，并沿左纵隔边缘向下延伸。非精原细胞瘤包含近水样密度区域（囊肿形成和/或坏死）以及软组织密度区域。尽管在组织学确诊之前CT特征可能提示诊断，但CT最重要的作用是评估疾病范围和监测治疗反应。
