Objective To probe the clinical value of transesophagealechocardiography(TEE) in diagnoses of mediastinal teratoma.Method Differential diagnosis of benign or malignant tumor was carried out on the bases of echocharacteristics,size,capsule lesion,boundary,growing speed,invasion and compression of tumor etc with TEE in twenty cases of mediastinal teratoma.Results The sensitivity,specificity and accuracy of the TEE diagnosis for mediastinal teratoma were 70%,94%,90% respectively.Conclusion TEE has an important value for diagnosis of mediastinal teratoma.%探讨经食管超声(TEE)对纵隔畸胎瘤的临床价值。方法 TEE观察肿瘤的回声特征、大小、包膜、边界、生长速度、浸润及压迫情况等方面来判断肿瘤的良恶性。结果 TEE能很好地显示20例纵隔畸胎瘤。判断畸胎瘤良恶性的灵敏度、特异度、准确度分别为70%、94%、90%。结论 TEE诊断隔畸胎瘤有重要临床价值。
