BACKGROUND:The aim was to retrospectively analyze the ultrasonographic and clinical characteristics of focal inflammatory masses and malignant masses of salivary gland by using B-mode ultrasound (US) and contrast-enhanced ultrasound (CEUS) for differential analysis. METHODS:The features of US and CEUS were retrospectively analyzed for 19 cases of focal salivary inflammatory masses and 45 cases of malignant salivary masses. All cases were confirmed by pathohistological examination. RESULTS:On B-mode US, the incidence of expansive growth patterns of malignant salivary masses (44.4%, 20/45) was significantly higher than that of focal salivary inflammatory masses (15.8%, 3/19) (p = 0.029). The rate of lymphadenopathy surrounding salivary glands of malignant salivary masses (42.2%, 19/45) was significantly higher than that of focal salivary inflammatory masses (15.8%, 3/19) (p = 0.042). On CEUS, clear enhancement margins were more common in malignant salivary masses (44.4%, 20/45) compared to focal salivary inflammatory masses (15.8%, 3/19) (p = 0.029); Rapid washout was more common in malignant salivary masses (82.2%, 37/45) than focal salivary inflammatory masses (31.6%, 6/19) (p < 0.001). Rapid washout on CEUS and craniocaudal diameter were independent predictive factors in differentiating salivary inflammatory masses and malignant masses according to binary logistic regression analysis. US and CEUS achieved a sensitivity of 80.0%, a specificity of 78.9%and an accuracy of 80.0%for discrimination between salivary inflammatory masses and malignant masses. CONCLUSION:Therefore, a multimodal ultrasonographic pathway combining clinical manifestations, B-mode US and CEUS was needed to differentiate between salivary focal inflammatory masses and malignancies to avoid unnecessary biopsies.

超声和超声造影在区分唾液局灶性炎性肿块与恶性肿块中的应用:回顾性观察研究

背景:旨在回顾性分析唾液腺局灶性炎性肿块和恶性肿块的超声和临床特征,应用B超(US)和对比增强超声(CEUS)进行鉴别分析。方法:回顾性分析19例唾液腺局灶性炎性肿块和45例恶性唾液腺肿块的US和CEUS特点。所有病例均经病理组织学检查确诊。结果:在 B 型超声检查中,恶性唾液肿块(44.4%,20/45)的发生率显着高于局灶性唾液腺炎性肿块(15.8%,3/19)(p = 0.029)。恶性唾液腺肿块唾液腺周围淋巴结肿大发生率(42.2%,19/45) 显着高于局灶性唾液炎性肿块 (15.8%, 3/19) (p = 0.042)。在 CEUS 上,与局灶性唾液腺炎性肿块 (15.8%, 3/19) (p = 0.029) 相比,恶性唾液肿块 (44.4%, 20/45) 中清晰的强化边缘更常见;快速冲洗在恶性唾液肿块 (82.2%, 37/45) 中比局灶性唾液炎肿块 (31.6%, 6/19) 更常见 (p < 0.001)。根据二元逻辑回归分析,CEUS 上的快速冲洗和颅尾直径是区分唾液炎性肿块和恶性肿块的独立预测因素。US和CEUS在区分唾液炎性肿块和恶性肿块方面的敏感性为80.0%,特异性为78.9%,准确率为80.0%。结论:因此,
