Magnetic resonance imaging (MRI) is a high performance tool for morpho
logical assessment and tissue characterization in the presurgical work
-up of scrotal tumors. A wait-and-see attitude is now possible for ben
ign lesions identified as epidermoid cysts. Pathology examination rema
ins more pertinent for an exhaustive assessment of local extension, bu
t MRI can provide a convincing, ii not definitive, distinction between
seminomatous and non-seminomatous germ cell tumors.
