B超对胆囊内隆起型病变的鉴别诊断

为探讨Ｂ型超声对胆囊内隆起型病变的鉴别诊断，将３２例经手术病理证实的患者Ｂ超检查结果作了分析。结果显示：（１）各类不同病理性质的胆囊隆起型病变，其病变的大小、数目和发生部位均有一定差异。本组中息肉病变、腺瘤和腺癌其病灶最大直径均值分别为９ｍｍ、１９．８ｍｍ和４２ｍｍ。（２）声像图的形态也各异，胆囊息肉多为乳头状或颗粒状，呈强回声或等回声，有蒂与胆囊壁相连，后方不伴声影，腺癌为不规则乳头状或分叶状，呈强回声、基底窄，腺癌多为半圆形或圆球形，基底宽、内部回声强弱不均等特征。

Differential Diagnosis of Elevated Lesion in the Gallbladder by Ultrasonography

In order to evaluate the role of ultrasonography in differentiating elevated lesion of the gallbladder, we review the sonograpbic findings in 32 patients, all lesions were proved Pathologically. The results are: (1) The masses of different pathologic entities were varied in size. number and site. The maxium diameter of polyps, adenoma and malignant adenoma was 9mm. 19. 8mm and 42mm respectively; (2) Ultrasonographic features were also varied,Polyps were usually papillary,granular masses attached to the wall by peduncle were hyperechoic or isoechoic and without posterior acoustic shadows,adenomas were irregular,papillary or lobulated masses with a narrow base and were hyperechoic. Malignant adenomas were usually semicircular or round masses with wide base of inhomogeneous echoes.
