目的:评价CT对胸腺瘤的诊断价值。方法:对43例经临床、手术、病理证实胸腺瘤的CT表现进行回顾性分析。结果:侵袭性胸腺瘤23例,形态不规则,边界欠清晰,有不同程度胸膜和/或心包膜增厚、受侵,其中15例内部密度不均匀,实质部分呈轻-中度强化。非侵袭性胸腺瘤20例,形态规则,边界清晰,内部密度均匀,实质部分呈轻度均匀强化。结论:CT检查对胸腺瘤有较高的诊断价值,对指导临床治疗有重要意义。
Objective: To evaluate the diagnostic value of CT in thymoma. Methods: Retrospective analysis was performed on the CT features of 43 cases of thymoma confirmed by clinical, surgical and pathological findings. RESULTS: Twenty-three cases of invasive thymoma were irregular in shape, with unclear boundaries. The pleural and/or pericardial membranes were thickened and invaded in varying degrees. Of these, 15 cases had non-uniform internal densities and showed mild-moderate enhancement of parenchyma. There were 20 non-invasive thymomas with well-defined morphology, clear boundaries, uniform internal densities, and mild homogeneous enhancement of the parenchyma. Conclusion: CT examination is of high diagnostic value for thymoma and is of great significance for guiding clinical treatment.
