目的分析周围型小肺癌不同时期的动态CT变化,总结其形态学特征,以便提高诊断的准确性。方法对30例有CT完整随访资料、经病理或细胞学证实的周围型小肺癌进行了回顾性分析。结果周围型肺癌多以小结节形式出现,平均直径17mm,9例密度均匀,9例呈多结节融合状,6例边缘呈浅分叶,6例边缘有短细毛刺。少数以密度较淡的斑片状等不典型形式出现,酷似炎性改变。动态观察病灶均呈结节状,进行性增大,边缘多有分叶、毛刺和胸膜凹陷等周围型肺癌征象。结论当肺内出现边缘分叶、毛刺、胸膜凹陷等征象,直径<20mm的小结节时,或以往胸片、CT正常的中老年人肺内出现小结节,不管形态如何,均提示有肺癌的可能。
Objective To analyze the changes of dynamic CT in different periods of peripheral small lung cancer and to summarize its morphological characteristics in order to improve the diagnostic accuracy. Methods A retrospective analysis was performed on 30 cases of small peripheral lung cancer with CT complete follow-up data and confirmed by pathology or cytology. Results The peripheral lung cancer mostly appeared in the form of small nodules. The average diameter was 17mm. The density of 9 cases was uniform. Nine cases had multi nodules fusion. The margins of 6 cases were shallow lobes. A small number of milder forms of patchy and other atypical forms, resembles inflammatory changes. Dynamic observation of lesions were nodular, progressive increase in the edge of more leaves, burr and pleural indentation and other peripheral lung cancer signs. Conclusion When nodules of marginal lobe, burr and pleura are appeared in the lung, nodules of <20 mm in diameter or small nodules in the lung of middle-aged and elderly people with normal chest radiograph and normal chest CT, no matter what the morphology, Possible lung cancer.
