We report a case of genital sarcoidosis that presented characteristic features on MRI. A 25-year-old man sarcoidosis patient with ocular and lung lesions presented a painful mass in the left scrotum together with systemic symptoms of fever, appetite loss, headache, and stomach-ache during the tapering of steroids. The patient was hypercalcemic, and this was thought to be the cause of his systemic symptoms. MRI showed multiple nodules of bilateral testes and enlargement of bilateral epididymis; the patient was diagnosed with testicular and epididymal lesions of sarcoidosis. An increased steroid dosage improved his hypercalcemia and genital lesions.
