目的探讨肝胆管细胞癌的声像图及彩色多普勒特点。方法分析近8年来22例肝胆管细胞癌的声像图及血流特点,全部病例经手术或活检病理证实。结果按声像图特点分为三类:局限型17例,胆管型3例,囊肿型2例。肝胆管癌声像图常常呈强回声,边界不清,外形不规则。4例声像图表现典型的“蝴蝶征,”10例门静脉受侵。结论肝胆管细胞癌的二维声像图及彩色多普勒特点,对其临床诊断有重要意义。
Objective To investigate the characteristics of cholangiocarcinoma with sonography and color Doppler imaging. Methods 22 cases of cholangiocarcinoma in recent 8 years were analyzed with sonographic features and blood flow characteristics. All cases were confirmed by surgery or biopsy. The results according to the characteristics of sonography are divided into three categories: localized in 17 cases, 3 cases of bile duct, 2 cases of cyst. Hepatic cholangiocarcinoma often has a strong echogenic echo, the boundary is unclear, irregular shape. 4 cases of sonographic representation of the typical “butterfly sign,” 10 cases of portal vein invasion. Conclusions Two-dimensional sonography of cholangiocarcinoma and color Doppler features are of great significance for clinical diagnosis.
