肺癌骨转移的CT诊断(附36例CT分析)

CT Diagnosis of Osseous Metastasis of Lung Carcinoma (Report of 36 Cases)

笔者报告36例肺癌骨转移的CT表现,其中29例作X线平片检查。CT表现主要呈溶骨性骨破坏(69.5％),亦可呈成骨性(5.5％)或混合性(25％)骨破坏。CT扫描在发现和估价病变方面较X线平片敏感。如平片骨破坏发现率为75.8％,CT扫描为100％;平片显示软组织肿块发现率为13.7％,CT为61.1％。文中对肺癌骨转移的发病情况、转移途径及CT诊断和鉴别诊断等进行了讨论。

CT findings of bone metastases from Lung cancer in 36 cases was reported, 29 of which also had plain radiographs. On CT, the metastases presented as lytic type (69.5%), os-teoblastic type (5.5%), and mixted type (25%). CT is far more sensitive in detecting and more-vuseful in eveluating these lesions than routine radiography. For example, detectability was only 75. 8% with plain radiograph and 100% with CT. Soft tissue masses were detected in 13.7% with plain radiography, and in 61.1% with CT. The incidene information, the metastatic road, the CT diagnosis and differential diagnosis of bone metastasis from lung cancer were disscussed.
