Scrotal Ultrasonography Revisited for Non-Palpable Testicular Tumors in the Prepubertal Age: Case Report

A 4-year-6 month old boy was seen for sexual precocity manifested by growth spurt, frequent penile erection, penile enlargement and pubic hair development. Scrotal ultrasonography -performed even though the testes were prepubertal, symmetric and bilaterally palpabledisclosed a tumor in the left testis. Left orchiectomy was performed and Leydig cell tumor was detected. Herein, we emphasize the role of scrotal ultrasonography in cases with gonadotropinindependent sexual precocity whereby the presence of non-palpable tumors should be excluded despite symmetrical testicles in the physical examination.
