目的 :研究纵隔肿瘤的 CT诊断特征和临床特点。方法 :55例纵隔肿瘤 ,其中恶性淋巴瘤36例 ,畸胎瘤 8例 ,胸腺瘤 6例 ,神经源性肿瘤 2例 ,胸内甲状腺、脂肪瘤与及心包囊肿各 1例。各例于手术前、放疗、化疗前行胸部 CT扫描和增强扫描。治疗后作 CT扫描对照。结果 :恶性淋巴瘤位于血管前或气管旁 ,畸胎瘤和胸腺瘤位于前纵隔 ,神经源性肿瘤位于后纵隔 ,恶性淋巴瘤放疗、化疗后对照疗效明显。畸胎瘤及胸腺瘤均以良性多见 ,手术效果好。结论 :CT能反映纵隔肿瘤的发生部位、组织与生长特征 ,易于定性诊断及定时随访观察疗效。
Objective: To study CT diagnosis features and clinical features of mediastinal tumors. Methods: There were 55 mediastinal tumors including 36 malignant lymphomas, 8 teratomas, 6 thymomas, 2 neurogenic tumors, 1 intrathoracic thyroid gland, lipoma, and pericardial cyst. Each case underwent chest CT scan and enhanced scan before surgery, radiotherapy, and chemotherapy. After treatment, CT scan control was performed. Results: The malignant lymphoma was located in front of the blood vessels or paratrachea. The teratoma and thymoma were located in the anterior mediastinum. The neurogenic tumors were located in the posterior mediastinum. The control of malignant lymphoma after radiotherapy and chemotherapy was effective. Teratoma and thymoma are more common benign and good surgical results. Conclusion : CT can reflect the location, tissue and growth characteristics of mediastinal tumors. It is easy to qualitative diagnosis and regular follow-up observation of curative effect.
