Secondary diffuse large B cell lymphoma involving the prostate in a 66-year-old male with a normal serum prostate-specific antigen level (0.795 ng/mL) and tear-like pain in the lower abdomen for 1 month. a, b T2WI shows a homogeneously isointense mass in the prostate with extraprostatic extension and invasion of the seminal vesicles. c, d DWI at a b-value of 1400 s/mm² and ADC maps show that the mass exhibits observably restricted diffusion. e DCE imaging shows moderate enhancement of the mass. f DWI at a b-value of 800 s/mm² shows slightly enlarged pelvic lymph nodes
