乳头状腺癌做为肺腺癌的一个亚型尚缺乏其放射学特征的报道。作者收集了1994年11月～1997年12月期间经手术病理证实的原发性肺腺癌153例,发现其中仅有3例符合下述乳头状腺癌病理组织学标准:①以纤维血管核心为支架的乳头状结构,杂乱排列成二级、三级分支状和丛状。②乳头状结构占据75%以上的瘤体.
Papillary adenocarcinoma as a subtype of lung adenocarcinoma is still lacking in its radiological characteristics. The authors collected 153 cases of primary lung adenocarcinoma confirmed by surgery and pathology between November 1994 and December 1997. Only 3 of them were found to meet the following histopathological criteria for papillary adenocarcinoma: The papillary structure of the stent is disorderly arranged in secondary and tertiary branches and plexiform. 2 The papillary structure occupies more than 75% of the tumor body.
