摘要
目的探讨纵隔内原发性精原细胞瘤的CT表现。方法回顾性分析7例经病理证实的纵隔内原发性精原细胞瘤的CT表现。结果肿瘤均位于前中上纵隔,呈类圆形结节、不规则形肿块、斑片状影,病灶大小不一,大部分较大,肿瘤密度不均,内出现散在坏死灶5例,未见钙化病例,增强后肿瘤不均匀轻-中度强化,坏死灶无强化。边界清楚2例,周边浸润5例,累及心包致心包增厚1例,上腔静脉综合征3例;1例侵及邻近胸膜;无肺部及心腔侵犯病例。所有病例均未发现肿大淋巴结,无心包积液、胸腔积液产生。结论原发性纵隔精原细胞瘤的CT表现有一定的特征性,但缺乏特异性,明确诊断仍需依靠实验室检查及病理。
Objective To explore the CT findings of the primary mediastinal seminoma. Methods The CT findings of 7 patients with primary mediastinal seminoma proven by histological examinations were retrospectively analyzed. Results All 7 lesions located in the front middle-upper mediastinum, which were round nodules or irregular shaped lumps or patchy shadow always with large sizes. The tumers were showed monuniform density inside the tumors and were enhanced lightly or medially, within scattered necrosis in five case. The round of the lesions were dear in two cases,surrounding infiltrates in five cases, while invading pericardium caused pericardial thickening in one case. In three patients associated superior ve na cava syndrome was found, and in one patient, adjacent pleura was invaded. No cases showed that lungs and heart chamber was invaded. All the cases were not found in the lymph nodes or pericardial effusion or pleural effusion. Conclu sion CT findings of primary mediastinal seminoma have characteristics but lack of specifity. Diagnosis still depends labo ratory examination and pathology.
