To study the ultrasound (US) features of scrotal adrenal rest tissue in congenital adrenal hyperplasia (CAH).
Gray-scale and color Doppler US examinations were performed of scrotal masses in eight patients. The masses were evaluated for size, location, echogenicity, sound attenuation, and vascularity.
Seventeen intratesticular masses and one extratesticular mass were examined. All were hypoechoic except for one intratesticular mass that contained hyperechoic areas. Six masses demonstrated sound attenuation. The mediastinum testis was found in the center of 11 of the 17 intratesticular masses. At color Doppler US, six masses were hypervascular, seven were isovascular, and five were hypovascular relative to the normal testicle. All intratesticular masses contained vascular structures that entered them from the normal testis without change in course or caliber. Eleven masses showed a spoke-like pattern of converging vessels.
The US features of scrotal adrenal rests assist diagnosis of CAH.
研究先天性肾上腺皮质增生症（CAH）患者阴囊肾上腺残余组织的超声（US）特征。
对8例患者的阴囊肿物进行灰阶及彩色多普勒超声检查。评估肿物的大小、位置、回声、声衰减及血管情况。
共检查了17个睾丸内肿物及1个睾丸外肿物。除1个睾丸内肿物含有高回声区外，其余均为低回声。6个肿物表现出声衰减。17个睾丸内肿物中有11个肿物的中心可见睾丸纵隔。在彩色多普勒超声检查中，相对于正常睾丸，6个肿物为高血供，7个为等血供，5个为低血供。所有睾丸内肿物均含有从正常睾丸进入肿物的血管结构，其走行及管径无改变。11个肿物显示出辐轮状的血管汇聚模式。
阴囊肾上腺残余组织的超声特征有助于先天性肾上腺皮质增生症的诊断。
