摘要
目的 分析总结肺腺癌CT征象特点 ,探讨病理基础 ,加强对本病的认识 ,提高诊断准确率。方法 收集经病理证实的中低分化腺癌 71例 ,并对其CT表现进行全面分析 ,其中 65例结合首次胸片正侧位观察 ,以求定位准确。结果 ①多原发、多形态 ,周围型多于中央型 ;②病灶边缘以分叶征、星芒状毛刺、界面锯齿征为主要特征 ;③癌性支气管充气征、空泡征和结节征为主要内部表现 ;④病变周围以癌性卫星灶 (5 7.7% )为特点 ,肺不张少见 ;⑤腺癌极易侵犯胸膜 ,叶间胸膜转移 49.2 % ,合并胸水 43 .6% ,远处转移以骨转移较多。结论 提高和加深对特征表现的认识 ,仔细观察、全面分析有助于提高诊断准确率 ,避免误诊。
Purpose To analyze the CT features of pulmonary adenocarcinoma,study the pathological basis and improve the diagnostic accuracy. Methods Seventy one cases of moderately and poorly differentiated pulmonary adenocarcinoma proved by bronchfiberscopy,operation or biopsy were collected. Their CT features were studied comprehensively, in which 65 cases were observed with their first chest film in order to locate accurately. Results ①There were more multiprimary,multiform in peripheral types the in central ones. ② Lobulation,long and stiff spiculation and sawtooth interface were imaging characteristic in their margin. ③ Carcinous bronchiologram,vacuole and nodule sign were major internal features. ④ Carcinous satellite focuses (57.7%) were typical signs around the lesion. Atelectasis was seldom found. ⑤Adenocarcinoma often infiltrate pleura. Pleural effusion was found in 43.6%,interlobar pleural metastasis was found in 49.2%,destruction of bone was majority in distant metastasis. Conclusion It is important to recognize the characteristic appearance in order to improve diagnostic accuracy and avoid misdiagnosis or leave out.
