细支气管肺泡癌的X线CT诊断

目的提高细支气管肺泡癌(BAC)的X线、CT诊断水平.材料与方法回顾性分析24例BAC的X线、CT表现,将其分为结节型、炎症型和弥漫型.结果结节型7例,均为单发结节.炎症型6例,两肺多发斑片状影4例,大叶实变2例.弥漫型11例,两肺呈细小结节影10例,网状结节影1例.单侧或双侧胸腔少量积液8例,心包大量积液5例,双侧肺门淋巴结增大3例.胸部及远处骨质破坏6例.结论BAC影像表现多种多样,炎症型需与肺结核、肺炎等鉴别.仔细观察、分析X线、CT征象并结合临床表现与治疗情况,可提高BAC的诊断正确率.

X-ray and CT Diagnosis of Bronchioloalveolar Carcinoma

Purpose: To improve the diagnostic accuracy of the bronchioloalveolar carcinoma (BAC) on X ray film and CT scan. Materials and Methods: X ray and CT features of BAC of 24 cases were retrospectively analysed. It was divided into three types: nodular, inflammatory and diffuse types. Results: Nodular group was solitary mass in 7 cases. Inflammatory group showed one or two lobes consolidation in 2 cases and multiple biateral patch or consolidation in 4 cases. Diffuse type had 11 cases, showing widespresd small node in 10 cases and reticulonodular shadows in 1 case. Invasion or metastasis signs included: a few pleural effusion in 8 cases, a lot of percardial effusion in 5 cases, bilateral hilar lymph node enlargment in 3 cases, multiple destruction of bone in 6 cases. Conclusion: BAC is found various imaging manifestations. Inflammatory type of BAC could be differentiated from pulmonary tuberculosis and pneumonia. It is possible to increase the accuracy rate of BAC by careful observing and analysing X ray and CT appearances and combining with clinical findings and treatment results.
