Diagnosis of Testicular Adrenal Rest Tumors on Ultrasound: A Retrospective Study of 15 Cases Report

The aim of this study was to evaluate the imaging features of testicular adrenal rest tumors (TARTs) on baseline ultrasound (BUS). The imaging features of 30 TART lesions pathologically or clinically confirmed in 15 patients who had undergone BUS were evaluated, and the sonographic characteristics of the lesions were analyzed. All 15 cases were bilateral and located near the testicular mediastinum. Approximately 56.7% (17/30) of the TART lesions exhibited homogeneous hypoechogenicity, 36.7% (11/30) of the lesions exhibited heterogeneous hypoechogenicity, and 6.6% (2/30) of the lesions exhibited heterogeneous isoechogenicity. In addition, 76.7% (23/30) of the lesions exhibited a rich blood supply, whereas 23.3% (7/30) of the lesions exhibited a scarce blood supply. The sonographic characteristics of the TARTs were bilateral growth, location adjacent to the testicular mediastinum, hypoechogenicity, and rich blood supply, which may play important roles in early clinical diagnosis.
