Testicular microlithiasis is a rare cause of testicular enlargement. An 8.5-year-old boy presented with bilateral testicular enlargement accompanied by no other pubertal signs. His bone age was 8.5 years and serum levels of luteinizing hormone and follicle-stimulating hormone after gonadotropin-releasing hormone stimulation were within prepubertal limits. Scrotal ultrasonography showed multiple echogenic microcalcifications that are indicative of microlithiasis in both testes. During 2-year follow-up, he developed clinical manifestations of early puberty between 9.5 and 10.5 years of age. Testicular microlithiasis should be considered when boys show bilateral testicular enlargement without other findings of puberty.
