摘    要:目的分析腺癌空洞型肺转移瘤的CT表现特点,提高对腺癌空洞型肺转移瘤的认识。方法收集经临床和病理证实的腺癌空洞型肺转移瘤16例,对其CT表现进行回顾性分析。结果腺癌空洞型肺转移瘤中空洞的CT表现可分为小环形、泡样、不规则形和囊样空洞。16例中56.3%来源于肺腺癌,其中97.0%表现为小环形空洞;来自肺外腺癌的转移性空洞形态多样,其中以泡样空洞和小环形空洞为主。转移性空洞多分布于肺外围及胸膜下,多为直径<5mm的薄壁空洞,边缘光滑或毛糙;约7.1%空洞直径>2.0cm且具有分叶、毛刺、壁结节等恶性空洞的特征。结论腺癌空洞型肺转移瘤的CT表现具有一定的特征,并与原发灶的病理类型有关。

关 键 词:腺癌  空洞  肺转移瘤  体层摄影术,X线计算机

Abstract:Objective To study CT features of cavitary pulmonary metastases from adenocarcinomas and to improve the knowledge of this kind of pulmonary metastases.Methods CT findings of cavitary pulmonary metastases from adenocarcinomas proven by clinic or pathology in 16 cases were retrospectively analyzed. Results Cavitary pulmonary metastases from adenocarcinomas presented as small circular, bubble, irregular or cystic cavity . 56.3% in 16 cases originated from lung adenocarcinomas , in which 97.0% appeared as small circular cavity . Metastatic lung adenocarcinoma originated from other adenocarcinoma showed on CT mainly as bubble and small circular cavity. Cavity-likeshadows were often multiple thin wall lesions and distributed under pleural, and pulmonary periphery with smooth or coarse margin, anddiameters were less than 5 mm. 7.1% lesions was more than 2.0 cm in diameter, and had the characteristics of malignant cavities such as lobulation, coarse margin and wall nodules.Conclusion Cavitary pulmonary metastases from adenocarcinomas have certain CT features and its occurrence is related to the pathologic type of the primary malignancy.
Keywords:adenocarcinoma  cavity  pulmonary metastases  tomography   X-ray computed
