Abstract:

Objective　To analyze the ultrasonic image characteristics of testicular adrenal rest tumors (TART), in order to improve the diagnostic value of ultrasonography. Methods　The clinical data of 10 male patients aged 6 to 26 years who were diagnosed as TART with a history of congenital adrenal hyperplasia (CAH) for many years in the Children's Hospital Affiliated to Zhengzhou University from January 2018 to August 2022 were collected. The characteristics of ultrasound images were summarized. Results　All the 10 cases involved bilateral testis. Ultrasonography showed 23 focal lesions, 16 of which were located in the testis hilum and 7 were located next to the mediastinum of the testis. Testicular volume was normal in 6 cases (60.0%) and enlarged in 4 cases (40.0%). The testis mediastinum was clearly displayed in 9 cases (90.0%). All the 23 lesions (100.0%) had clear boundary without envelope, of which 20 were hypoechoic (87.0%) and 3 were isoechoic (13.0%); there were 16 lesions with irregular shape (69.6%) and 7 lesions with quasi-circular shape (30.4%); there were 14 lesions with abundant blood supply (60.9%) and 9 lesions with scarce blood supply (39.1%). Conclusions　TART is mainly characterized by bilateral testicular involvement. The low echo area of porta testicle or mediastinum of testicle is the characteristic ultrasonography of TART. The diagnosis of TART can be made in combination with history of CAH.
