Diagnosis of a primary testicular lymphoma by echography and magnetic resonance imaging.

We here describe a primary large B cell non-Hodgkin lymphoma of the right testicle in a 73-year-old male diagnosed with echography and magnetic resonance imaging. Treatment was based upon orchiectomy and chemotherapy, without any recurrence 2 years later. Ultrasonography and magnetic resonance findings with normal serum tumoural markers (AFP and B-HCG) can differentiate these tumors from germinal testicular tumors.
