目的分析肺转移瘤的不典型CT影像表现,以提高对该病的认识。方法回顾性分析15例经临床、手术及病理证实有原发肿瘤、肺部出现不典型转移病灶病例的CT表现。结果15例转移瘤的不典型CT表现:孤立性肺转移5例,空洞性肺转移3例,钙化性肺转移5例,磨玻璃样肺转移2例。各型转移瘤可单独存在,也可相互重叠。结论不典型肺转移瘤缺乏典型CT表现,结合临床及CT征象,可以对表现不典型的肺转移瘤作出正确诊断。
Objective To analyze the atypical CT images of lung metastases to improve the understanding of the disease. Methods A retrospective analysis of 15 cases of clinically, surgically and pathologically confirmed primary tumors, CT findings of atypical cases of lung metastases. Results 15 cases of atypical CT findings: isolated lung metastases in 5 cases, empty lung metastases in 3 cases, calcified lung metastases in 5 cases, ground glass-like lung metastases in 2 cases. Each type of metastases can exist alone, but also overlap each other. Conclusions Atypical pulmonary metastases lack typical CT findings. Combined with clinical and CT findings, it is possible to correctly diagnose atypical pulmonary metastases.
