Future Directions in the Study and Management of Congenital Adrenal Hyperplasia due to 21-Hydroxylase Deficiency

Figure 8. Testicular adrenal rest tissue masses often surround the mediastinum testes ( ) ( ), and are bilateral, intratesticular, and hypoechoic ( ). Testicular adrenal rest tissue masses are seen equally as well on ultrasonography and magnetic resonance imaging. Most of these masses are hypointense on T2-weighted images ( ) and isointense on T1-weighted images, with diffuse enhancement post-contrast ( ). Large testicular adrenal rest tissue ( ) typically shrinks or disappears ( ) with higher-dose glucocorticoid therapy.
