case_images: The left testis contained three round-to-oval hypoechoic heterogeneous lesions, 0.9-2.3 cm in diameter, located in the mediastinum testis (Figure 1).
case_images: T1-weighted magnetic resonance image of the pelvis showing ectopic position of the left testis in front of the left commoun iliac vessels.

case_images: Coronal images of the pelvis confirmed the ectopic position of the left testis, in front of the left common iliac vessels (Figure 2).

case_images: T1-weighted images and appeared hyperintense on T2-weighted images (Figure 3). They showed a homogeneous enhancement pattern.
case_images: Testicular T2-weighted images showing hypointense lesion in the right epididymis, with central areas of high signal intensity.

case_images: In addition, MRI study of the testis showed right epididymal mass exhibiting the following features: isointensity on T1-weighted images, marked enhancement on postcontrast images, and hypointensity on T2-weighted images with central areas of high signal intensity (Figure 4).
case_images: High power view of the epididymal tumor showing nests of polygonal cells with abundant granular eosinophilic cytoplasm (H and E, x400). No necrosis or Reinke's crystal is seen.

case_images: Both the lipochrome pigment and crystalloids of Reinke's were lacking (Figure 5).
case_images: Immunoperoxidase stain for vimentin showing strong cytoplasmic positivity (IHC, x100).
