隐蔽性肺癌的CT诊断

CT Diagnosis of Hidden Lung Cancers in Chest

目的 评价CT对隐蔽性肺癌的诊断价值。方法 回顾分析53例经病理证实的隐蔽性肺癌,全部病例均有 胸部平片和CT检查。结果 53例隐蔽性肺癌的主要隐蔽部位有肺尖、肺门区、支气管内、奇静脉食管隐窝、纵隔、 脊柱旁、心脏前后、膈肌后及膈肌上。胸部平片检出病灶6例(11．3％),CT检出53例(100％)。结论 隐蔽性肺癌 平片容易漏诊,CT可清楚显示X线平片不易显示的隐蔽性病变。对临床症状明显、平片检查阴性者,CT检查是最 好、最有效的检查方法之一。

Objective To evaluate the diagnostic value of CT in detecting lung cancers in hidden locations in chest. Methods 53 cases of hidden lung cancers confirmed by pathology were reviewed and analyzed, and all cases had plain film and computed tomography. Results Locations of 53 hidden lung cancers included the apex of lung, hilus of lung, bronchus,azygoespohageal concavity, mediastinum, parvertebrae, fore-and-aft heart blind area and diaphragm. 6 cases of chest hidden pathological changes were showed by plain film（ 11.3 % ）, 53 cases by CT（ 100 % ）. Conclusion The accuracy of chest plain film diagnosis is low. The hidden lung cancer is well seen in CT,CT scans is the most important method in the diagnosis of hidden lung cancers for patients who are suspected suffering from lung cancer.
