胸腺瘤的X线平片、CT诊断(附23例分析)

X-ray and CT diagnosis of thymoma(23 cases analysis)

目的:评价X线平片、CT对胸腺瘤的诊断价值。方法:回顾分析23例经手术病理证实的胸腺瘤的临床、X线、CT表现,将结果与病理进行对照分析。结果:非侵袭性胸腺瘤X线平片诊断符合率为66.7%,CT诊断符合率为86.7%。侵袭性胸腺瘤X线诊断符合率为25%,CT诊断符合率为87.5%。CT敏感性和特异性较胸片为高,尤其判断胸腺瘤是否具有“侵袭性”方面CT明显优于X线平片。结论:X线平片是诊断胸腺瘤的基本方法,CT是诊断胸腺瘤最有效的方法,二者可以互相结合。病理最终可确定组织来源和性质,CT是病理判断胸腺瘤是否具有“侵袭性”的重要补充。

Objective. To evaluate the X-ray and CT diagnostic value of Thymoma. Methods. Clinical and imaging material of 23 cases of thymoma confirmed by surgery and histopathology were reviewed. The result of clinical and imaging material were compared with histopathology. Results： The diagnosis coincidential rate in noninvasive thymoma was 66.7% on X-ray film , was 86.7% on CT. The diagnosis coincidential rate in invasive thymoma was 25% on X-ray film , was 87.7%on CT. The sensitivity and peculiarity of CT was superior to X-ray film especially, the aspect of which distinguished whether the Thymoma was invasive or not was superior to X-ray. Conclusion.CT was the most efficient method of diagnoing thymoma. Both of the methods could be joined in integrated.
