摘要
目的：探讨罕少见纵隔肿瘤的范畴及影像学诊断。材料与方法：分析罕少见纵隔肿瘤５２例，其中４７例摄有正侧位胸片，２０例进行了ＣＴ检查。结果：作者提出罕少见纵隔肿瘤范畴包括三方面：①肿瘤本身罕少见；②位于不常见部位的常见纵隔肿瘤；③伴罕少见影像学表现的常见纵隔肿瘤。某些罕少见纵隔肿瘤在发病年龄、肿瘤部位、肿瘤密度及伴发改变方面具有一定特征。另外，本文病例术前未能正确诊断者高达７８．８％，其中５９．６％的病例Ｘ线及ＣＴ诊断与病理结果不符，作者对罕少见纵隔肿瘤误诊原因进行了分析。结论：提高医师对罕少见纵隔肿瘤及其范畴的认识，多种检查结果（胸部平片、ＣＴ或ＭＲＩ结果并结合临床表现）综合分析，对提高该组疾病的诊断准确率有重要价值。
Objective: To investigate the extent and imaging diagnosis of rare mediastinal tumors.Materials and Methods:52 cases of rare mediastinal tumors were analysed retrospectively, in which 47 cases were studied by PA and lateral chest radiograms and 20 cases CT scan.Results:The author pointed out that the common mediastinal tumors situated in rare area or with rare imaging manifestation should also be classified to the rare mediastinal tumors; some rare mediastinal tumors had also certain features on age, site, neoplasm density and concomitant manifestations. Otherwie, 78.8% of this series did not make definite diagnosis before operation and 59.6% were misdiagnosed as other diseases. The reason of misdiagnosis was discussed in the paper.Conclusion: To raise the accurate diagnosis rate of rare mediastinal tumors, it was important to enhance doctor's recognition of rare mediastinal tumors and to analyze synthetically the results of chest film、 CT or MRI and clinical manifestations.[HJ5mm〗
