Mixed sex-cord stromal tumor of the testis: evaluation by ultrasonography and magnetic resonance imaging.

We report on the sonographic (US) and magnetic resonance imaging (MRI) appearance of a mixed sex-cord stromal tumor of the testis. The case is notable due to its rarity, its unusual imaging characteristics as correlated with pathology, and the ability of MRI, in this particular case, to give more complete information than US as to the character of the lesion.
