We present a case of spontaneous regression of gonadoblastoma in Swyer syndrome. Magnetic resonance imaging showed significant tumor shrinkage over two months with several changes in appearance:higher intensity on T2-weighted images, less diffusion restriction, and more delayed contrast enhancement. As with type Ⅱ germ cell tumors(GCTs)of the testis, GCTs from dysgenetic gonads may regress spontaneously, even when the internal genitalia show a female pattern.
