The aim of the study was to define ultrasonographic morphologic features characteristic of pleomorphic adenoma and adenolymphoma (Warthin's tumor).
Documentation of 31 ultrasonographic examinations of 20 pleomorphic adenomas and 10 Warthin's tumors in 28 patients was analysed. All cases were confirmed by fine needle aspiration biopsy or/and histopathological examination. Estimated ultrasound criteria were: borders (well-defined, predominantly well-defined, ill-defined), shape (lobulated, oval, irregular), echogenicity (increased, decreased), structure (homogeneous, slightly inhomogeneous, inhomogeneous) and presence of irregular anechoic areas within a tumor.
100% of the lesions were hypoechoic. 80.6% of all tumors were well-defined. The remaining 19.4% had predominantly well-defined borders. 55% of pleomorphic adenomas had a lobulated shape. Almost equal percentages of Warthin's tumors were lobulated, had an oval and irregular shape. Irregular echolucent areas were present in six of 11 examinations of Warthin's tumors and in one pleomorphic adenoma.
Ultrasonography is a useful method for the evaluation of pleomorphic adenomas and Warthin's tumors and sometimes it might allow to suggest the nature of a tumor if a certain sonographic pattern is present.
本研究旨在明确多形性腺瘤和腺淋巴瘤(沃辛瘤)的超声形态学特征。
分析了28例患者中20例多形性腺瘤和10例沃辛瘤的31次超声检查记录。所有病例均经细针穿刺活检或/和组织病理学检查确诊。评估的超声标准包括:边界(清晰、大多清晰、不清晰)、形态(分叶状、椭圆形、不规则形)、回声(增强、减弱)、结构(均匀、稍不均匀、不均匀)以及肿瘤内不规则无回声区的存在情况。
100%的病变为低回声。80.6%的肿瘤边界清晰。其余19.4%的边界大多清晰。55%的多形性腺瘤呈分叶状。沃辛瘤呈分叶状、椭圆形和不规则形的比例相近。在11次沃辛瘤检查中有6次以及1例多形性腺瘤中存在不规则无回声区。
超声检查是评估多形性腺瘤和沃辛瘤的有用方法,有时如果出现特定的超声表现模式,可能有助于提示肿瘤的性质。
