阴囊内腺瘤样瘤的超声表现

Ultrasonic appearances of intrascrotal adenomatoid tumor

目的探讨阴囊内腺瘤样瘤的声像图表现。方法回顾性分析21例经手术病理证实的阴囊内腺瘤样瘤的超声表现。结果阴囊内腺瘤样瘤大致可分为三型：①均匀回声型：15例，超声表现为均匀低、等、高回声结节，其中低回声5例，等回声8例，高回声2例；5例睾丸白膜腺瘤样瘤均为该型，2例为等回声，2例为低回声，1例为高回声，高回声结节后方回声略衰减。②边缘晕环型：4例，超声表现为附睾或睾丸鞘膜上类圆形或卵圆形结节，结节中央为低回声，边缘呈高回声晕环。③混合回声型：2例，超声表现为附睾混合回声结节，呈囊实性，1例囊性区形态不规则，内透声差，1例囊性区内透声好，囊壁上见小乳头状突起。结论超声对阴囊内腺瘤样瘤的诊断具有重要价值，边缘晕环型具有一定声像图特点。

Objective To explore the sonographic features of intrascrotal adenomatoid tumor. Methods The sonographic features of 21 cases with intrascrotal adenomatoid tumor confirmed by surgery and pathology were retrospectively analyzed. Results Twenty-one cases with intraserotal adenomatoid tumor could be typed into 3 ultrasonic patterns; （1） The homogeneous echo type：15 cases, their ultrasonic features were homogeneous echo,including 5 cases with low echo, 8 case with equal echo, and 2 case with high echo,5 cases with testicular albuginea adenomatous tumors were also homogeneous echo,2 cases of equal echo,2 cases of low echo and 1 case of high echo that was posterior echo attenuation slightly. （2） The edge halo type： 4 cases, they showed the epididymis or testis sheath round or oval nodules, of which the middle was low echo and the edge is high echo halo ring. （3） The mixed echo type：2 cases,they showed cystic mixed echo of epididymis nodules, 1 case with irregular cystic areas and poor sound transmission, while the other one with good sound transmission cystic areas and a small papillae on the wall. Conclusions Sonography is a valuable method for diagnosis of intrascrotal adenomatoid tumor. The edge halo type has sonographic features.
