摘　　要：目的探讨涎腺黏液表皮样癌的声像图特点。方法结合病理特征，对经手术病理证实的22例涎腺黏液表皮样癌的声像图表现进行回顾性分析。结果22例黏液表皮样癌超声表现为实性或囊实性回声，11例高分化黏液表皮样癌边界尚规整，与周围组织分界尚清，其中7例内部为均匀实性回声，4例以实性回声为主，局部可见囊实性回声，血流均呈0～1级。5例低分化黏液表皮样癌形状不规整，边界不清，均以不均匀实性回声为主，后方回声轻微减低，其中2例病灶内见点状或斑片状强回声，血流均呈Ⅱ～Ⅲ级。6例中分化黏液表皮样癌超声为实性低回声，声像图趋向于高分化黏液表皮样痛。结论黏液表皮样癌具有涎腺恶性肿瘤常见的灰阶声像表现，但彩色多普勒表现具有特征性。超声检查结合临床表现有助于正确诊断。Objective To investigate the uhrasonographie characteristics of mueoepidermoid carcinoma （MEC） of salivary glands. Methods Twenty two patients with MEC of salivary glands were analyzed retrospectively by uhrasonography combining with the pathologi- cal characteristics. Results Twenty-two eases were solid or cystic and solid echo. The boundary of 11 cases with well - differentiated MEC was neat. Among 11 cases with well - differentiated MEC,7 cases were homogeneous solid internal echo,4 cases with solid echo mainly, being cystic or solid local,CDFI grade 0 - 1. Among 5 cases with poorly differentiated MEC,the shape was irregular, boundary was not clear,solid echo was the main, rear echo slightly reduced, and CDFI was grade 2 -3.6 cases with intermediate differentiation were sim- ilar to the well - differentiated MEC. Conclusion MEC had general features on grey scale uhrasonogram as a malignant tumor of salivary glands, but specific features on color Doppler imaging. Uhrasonography combined with clinical information contributes to the diagnosis of MEC of salivary glands.
