Primary diffuse large B-cell testicular lymphoma: magnetic resonance imaging findings.

Testicular lymphoma represents the commonest testicular malignancy in men older than 50 years. MR imaging of the scrotum is an efficient supplemental diagnostic tool in the evaluation of scrotal diseases. We report two cases of primary diffuse large B-cell testicular lymphoma, presented in men over the age of 50 years. MR imaging revealed the presence of a hypointense intratesticular mass lesion on T2-weighted images, strongly and heterogeneously enhancing after gadolinium administration.
