Sonographically detected testicular microlithiasis is an uncommon condition, which in recent years has been demonstrated with increased prevalence in patients with testicular tumors. We report a case of a 31-year-old man with left testicular carcinoma and right intratubular germ cell neoplasia diagnosed by biopsy of the right testis at the time of left radical orchiectomy. In this case, preoperative ultrasound revealed right testicular microlithiasis, signaling the presence of intratubular germ cell neoplasia. We propose ultrasound as a noninvasive tool for selecting patients for testicular biopsy.
