Ultrasonic appearances of intrascrotal adenomatoid tumor / 中华超声影像学杂志

ABSTRACT

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 intrascrotal adenomatoid tumor could be typed into 3 ultrasonic patterns(1) The homogeneous echo type15 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 type4 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 type2 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.
