Isolated granulomatous orchitis: MR imaging findings

Abstract

Isolated granulomatous orchitis is a rare chronic testicular inflammation, which should be differentiated from testicular malignancies on scrotal imaging. We present a case of a 33-year-old man, with a diffuse pattern of granulomatous orchitis, confirmed by means of testicular biopsy. MR imaging of the scrotum revealed the presence of two small-sized intratesticular lesions, hypointense on T2-weighted images, not enhancing after gadolinium administration suggesting the diagnosis of benignity.
