二维及彩色多普勒超声对涎腺少见肿块的诊断价值

Evaluation of two - dimensional ultrasonography and color Doppler flow imaging in diag-nosis of unusual masses in salivary glands.

目的 评价二维及彩色多普勒超声对涎腺少见肿块的诊断价值。方法 收集应用二维及彩色多普勒超声诊断涎腺少见肿块22例。良性肿块13例,恶性肿瘤9例,所有病例均经手术及病理证实。结果 涎腺少见肿块中恶性肿瘤的彩色血流分级(Ⅲ+Ⅳ级占83％)明显高于良性肿块(Ⅰ+Ⅱ级占77％)。二维超声上囊肿,嗜酸性淋巴肉芽肿及脓肿有一定的特征性表现。彩超显示结节病与淋巴上皮病有较丰富的血流。结论 二维与彩超的联合应用在涎腺少见肿块的鉴别诊断中有较高的诊断价值。结节病与淋巴上皮病因有较丰富的血流须与恶性肿瘤相鉴别。

Purpose Evaluation of two - dimensional ultrasonography(2D) and color Doppler flow imaging(CDFI) in diagnosis of rare masses in the salivary glands. Methods This research included 22 patients with 13 benign and 9 malignant. All cases were confirmed by surgery and pathology . Results The mean color quantity scale of malignant rare masses in the Salivary glands( IK + IV scale, 83 %) was higher than that of benign ones ( I + II scale, 77 %). There were certainly features of 2D in cyst, eosinophilic granuloma and abscess. There was rich blood flow in sarcoidosis and lymphopithelial. Conclusion the results suggested that 2D combined with CDFI has relatively high value in the differential of rare masses in the salivary glands.The sarcoidosis and lymphoepithelial lesion ought to be distinguished from malignant mass due to their rich blood flow.
