患者男,66岁,1年前发现左侧耳前一蚕豆大小肿物,无疼痛、麻木等不适,未予任何治疗,现自觉肿块缓慢增大,约鸽蛋大小,遂来我院就诊。体格检查:左侧耳前可触及一大小约3.0 cm×2.0 cm×2.0 cm肿块,边界清,活动度尚可,门诊拟以“左腮腺肿块”收住入院。

患者男,66岁,1年前发现左侧耳前一蚕豆大小肿物,无疼痛、麻木等不适,未予任何治疗,现自觉肿块缓慢增大,约鸽蛋大小,遂来我院就诊。体格检查:左侧耳前可触及一大小约3.0 cm×2.0 cm×2.0 cm肿块,边界清,活动度尚可,门诊拟以“左腮腺肿块”收住入院。

 

超声检查:双侧腮腺内均见多个低回声,中央呈高回声,右侧最大者约1.3 cm×0.6 cm,左侧最大者约1.5 cm×0.9 cm。左侧腮腺内侧下极另见一大小为2.8 cm×1.9 cm的低回声,形态规则,边界清晰,内部回声不均质,后方回声增强,CDFI示其内血供稍丰富(图1)。

超声提示:①左侧腮腺内实性肿块;②双侧腮腺内多发性结节(淋巴结?)。术中见左侧肿块位于腮腺浅叶内,紧贴面神经总干,周围可见大量小淋巴结包绕,呈囊实性,最大直径约3.1 cm,包膜完整,将肿块完整切除送检,病理结果:左侧腮腺内Warthin瘤(淋巴乳头状囊腺瘤)。

 

讨论:

 

Warthin瘤又称淋巴细胞性乳头状囊腺瘤,是涎腺的一种良性上皮性肿瘤,由Warthin首先描述而命名。肿瘤由上皮组织和淋巴样组织组成,好发于50岁以上男性,生长缓慢,多为单发,左侧常见。超声显示肿块多位于腮腺后下极,边界清晰,回声低,部分可成液性,后方回声增强;CDFI示其内血供较丰富。

 

腮腺内Warthin瘤超声表现具有一定特异性,但与低度恶性的腮腺肿瘤或早期腮腺癌存在诸多相似之处,需要鉴别诊断。低度恶性的腮腺肿瘤或早期腮腺癌行为学上表现为生长缓慢,患者无明显感觉,超声显示其形态规则,边界尚清晰,内部回声均匀,其内血供欠丰富。超声造影可准确提供肿瘤内部的血供情况,而超声引导下肿瘤穿刺活检为定性诊断腮腺内肿瘤提供了有力依据。超声检查具有无辐射、可重复的优点,是诊断腮腺内肿瘤的重要方法。
