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
Objective To study the relationship between CT appearance and pathology in peripheral adenocarcinoma. Methods Eighty cases of lung adenocarcinoma (44 cases of well-differentiated adenocarcinoma, 23 cases of moderately differentiated adenocarcinoma and 13 cases of poorly differentiated adenocarcinoma) were collected and pathologically confirmed. CT signs and pathological differentiation were compared between the two groups. Results There were 35 cases (79.6%) of well-differentiated adenocarcinoma of air bronchus sign and vacuole sign, 7 cases of moderately differentiated adenocarcinoma (30.4%), and no sign of poorly differentiated adenocarcinoma. Poorly differentiated adenocarcinoma of deep lobes sign, burr sign, pleural indentation, vascular bundles signs of high incidence. Medium and poorly differentiated adenocarcinoma of lymph nodes and distant metastasis was significantly higher than that of well-differentiated adenocarcinoma. Conclusion CT bronchial air / air sign on upper nodules is of great significance for the qualitative diagnosis and prognosis of peripheral adenocarcinoma
