摘　　要：在回顾性分析经病理学证实的165例肺癌时,CT扫描发现21例肺癌内钙化,本文对钙化的形态、分布进行了分析,腺癌(14例)和鳞癌(6例)为主要细胞类型,腺癌多趋向于偏心点状和散在细颗粒状及弥漫不规则斑片状钙片。与良性钙化病变相比,除层状钙化外,肺癌可出现各种形态钙化。小于3cm结节出现弥漫性钙化易误诊为良性肉芽肿病变.如钙化性肿块伴有深分叶及毛刺征,纵隔肺门淋巴结肿大有助于提示肺癌诊断。165 Patients with the lung carcinoma proved pathologically were analyzed retrospectivly. CT scan showed 21 cases calcification within the tumor. We analyzed the pattern and distribution of calcification within tumor. Adenocarcinoma (14 patients) and squamous cell carcinoma (6 patients) were the major cell types. Adenocarcinoma tended to have peripheral punctate, multiple minute punctate and diffuse amorphous calcification. The pulmonary nodules less than 3 cm in diameter showed diffuse calcification easily misdiagnose the benign granuloma disease, CT scan showed calcification mass with lobulation, spiculation and hilar or mediastinal lymph node enlargment are helpful to suggest the diagnsis of the lung cancer.
