目的：探讨原发性支气管肺癌钙化的ＣＴ表现特征及其鉴别诊断。材料和方法：经病理证实的内有肉眼可见之钙化的原发性支气管肺癌１６例，回顾性分析ＣＴ像所见钙化的形态、大小和分布特征及与原发肿瘤大小和病理类型间的关系，并与病理对照研究，用非配对ｔ检验行统计学分析。结果：病灶直径２．０～１３ｃｍ，平均５．６ｃｍ。直径５ｃｍ以下者３例。周边型钙化８例，中心型者７例，另１例既有中心又有周边型钙化。钙化数目１例４枚，１例２枚，其余均为１枚。病理包括腺癌７例，鳞状细胞癌５例，小细胞癌２例，低度恶性肿瘤１例，未能分型１例。结论：原发性肺癌的钙化常见于较大的肿块内，常表现为小结节或斑点状，与钙化的分布无关。
Objective: To investigate the CT features and differential diagnosis of primary bronchogenic lung calcification. Materials and Methods: 16 patients with pathologically confirmed calcification of primary bronchial lung cancer were retrospectively analyzed for the morphology, size and distribution of calcification seen by CT images, and their relationship with primary tumor size and pathological types. , And compared with pathological studies, statistical analysis using non-paired t test. Results: The diameter of the lesion was 2.0-13cm, with an average of 5.6cm. 3 cases with a diameter of 5 cm or less. There were 8 cases of peripheral calcification, 7 cases of central type, and 1 case of peripheral calcification. The number of calcifications was 4 in 1 case, 2 in 1 case, and 1 in the rest. Pathology included 7 cases of adenocarcinoma, 5 cases of squamous cell carcinoma, 2 cases of small cell carcinoma, 1 case of low grade tumor, and 1 case of failure to be classified. CONCLUSIONS: Calcification of primary lung cancer is common in larger masses, often as small nodules or spots, and has nothing to do with the distribution of calcification.
