Patient Data

Age: 16 years
Gender: Male

Average size testicles with a focal, irregular, eccentric, hypoechoic lesion adjacent to the mediastinum testis in both testicles. No mass effect, narrowing or distortion is seen in the testicular vessels traversing through these lesions.

A well-defined eccentric lesion is seen adjacent to mediastinum testis in both testicles. These lesions are isointense on T1 and hypointense on T2-weighted images to the testicular parenchyma. No restricted diffusion is seen in these lesions. These lesions show moderate enhancement (more than the normal testicular parenchyma) on post contrast images.
