周围型肺腺癌的CT分析

目的　研究周围型腺癌的CT表现及病理之间的关系。方法　收集病理证实的肺腺癌 80例 (高分化腺癌 44例 ,中分化腺癌 2 3例 ,低分化腺癌 13例 ) ,对肿瘤的CT征象与病理上的分化程度进行比较分析。结果　空气支气管征 /空泡征高分化腺癌有 3 5例 ( 79.6% ) ,中分化腺癌 7例 ( 3 0 .4% ) ,而低分化腺癌无此征。低分化腺癌的深分叶征、毛刺征、胸膜凹陷征、血管集束征出现率高。中、低分化腺癌的淋巴结及远处转移明显高于高分化腺癌。结论　CT像上结节内空气支气管征 /空泡征对于周围型腺癌的定性诊断及预后判断有重要意义

Peripheral Adenocarcinoma:Analyses of CT Signs

Objective To evaluate the relationship between the CT features and pathology of peripheral adenocarcinoma.Methods Eighty patients with peripheral pulmonary adenocarcinoma (including 44 well-differentiated,23 moderate and 13 poorly one)confirmed by pathology were collected in this series.The comparative study on CT finding and pathologic data was done.Results Air bronchograms were seen in 35 cases (79.6%)in high differential adenocarcinoma and were seen in 7 cases(30.4%) in moderate differential adenocinoma but not seen in low differential ones.The emergeua rate of lobular sign,burr sign,sign of hollowed and sign of blood vessel bundle was high in low differentiated adenocarcinoma.Lymphnode metastases and distant matestasis in moderate-low differentiated adenocarcinoma were much more than that of high differentiated ones. Conclusion The air bronchogram in nodule on CT image is important in evaluating diagnosis and progrosis of peripheral adenocarcinoma.
