原发性支气管肺类癌的临床、X线及CT诊断

目的 探讨原发性支气管肺类癌的临床、胸部平片及CT诊断。方法 针对经手术及病理确诊资料完整的9例肺类癌，回顾性统计和分析其临床、胸部平片及CT表现。结果 临床主要表现为咳嗽6例(66．7％)，咳血5例(55．6％)，发热3例(33．3％)。胸部平片肿瘤位于右肺6例，左肺3例，8例呈圆或类圆形，密度均匀，2例见浅分叶。CT扫描6例中，2例圆形，4例(80％)分叶状，3例(50％)见中心密度减低的坏死区，肿瘤的平均直径4．3cm，平扫平均CT值37．6Hu，注入对比剂后6例均有不同程度增强，CT值平均上升39．8Hu。结论 肺类癌的表现缺乏特征性，但若能认真分析胸部平片及CT的每一征象，密切结合临床表现，完全可以提高本病术前诊断水平。

Diagnosis of Clinical, X-Ray and CT in Primary Bronchial-Pulmonary Carcinoid

Objective To investigate the clinical manifestations, chest plain film and CT diagnosis of primary bronchial-pulmonary carcinoid. Methods Nine cases of primary bronchial-pulmonary carcinoid confirmed by operation and pathology were analyzed retrospectively. Results The clinical manifestations were cough in 6 cases (66.7%), hemoptysis in 5 cases (55.6%), fever in 3 cases (33.3%). Chest plain film showed lesions of right lung in 6 cases and lesions of left lung in 3 cases. Lesions in 8 cases were circular or ellipse with homogeneous density. Lesions in 2 cases were lobulated. CT showed lesions in 2 cases were circular and 4 cases were lobulated, lesions in cases had necrotic area with low central density. The average diameter of the lesions was 4.3cm, the average CT value was 37.6Hu and lesions in 6 cases were enhanced up 39.8Hu averagely after the contrast medium adminastrated. Conclusion The diagnosis of primary bronchial-pulmonary carcinoid, which lack of typical clinical manifestations, could be improved when signs of the lesions on CT and plain film be studied carefully and combine with the clinical manifestations.
