Bilateral testicular adrenal rest tissue in congenital adrenal hyperplasia: US and MR features.
We describe magnetic resonance (MR) and ultrasonography (US) features of bilateral testicular adrenal rest tissue in a 20-yr-old man with congenital adrenal hyperplasia (CAH). Scrotal ultrasonology detected bilateral homogeneous hypoechoic lesions with well-defined margins and without evidence of sound attenuation. MR is useful in defining the size of lesions, because the contrast resolution is better than with sonography and allows an accurate definition of the extent of disease. This case suggests that US evaluation should be included in periodical follow-up of patients with CAH, while MR may be used in the case of rapid increase in the size of the testicular mass.
