纵隔肿瘤的CT影像和临床分析

CT scan and clinical analysis of mediastinal neoplasms

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。

Objectives:[WT5BZ]To study clinical presentations and CT features of mediastinal tumours.[WT5HZ]Methods:[WT5BZ]55 patients with mediastinal tumours were studied retrospectively.There were malignant lymphoma(36),teratoma(8),thymoma(6),malignant lymphoma(36) neurogenic tumours(2),thyroid gland of intrathoracic、lipomatosis(1),CT scan with and without contrast were performed before and after operations or radiotherapy or chemotherapy.[WT5HZ]Results:[WT5BZ]Malignant lymphoma in front of blood vessels or adjacency of wind pipe.Teratomas and thymomas tended to be located in the anterior mediastinum,Whereas neurogenic tumours predisposed to the posterior mediastinum.The effect were characteristic after malignant lgmphoma were performed radiotherapy or chemotherapy.More seen benign teratomas and thymomas,operational effect were characteristic.[WT5HZ]Conclusions:[WT5BZ]CT scan can mirror existence region、tissue and growing character of mediastinal neoplasms.CT scans are accurate in the diagnosis and follow-up of mediastinal tumours.
