Magnetic resonance imaging (1.5 Tesla) with a surface coil. (a) Polycyclic mass (arrow) cephalad to the right testicle with no signal intensity on T2-weighted imaging. The mass is clearly detached from the testicle (coronary section). (b) The intrascrotal mass (arrow) shows inhomogeneous signal intensity on T1-weighted imaging (coronary section). (c) The mass (arrow) shows only low and inhomogeneous uptake of gadolinium contrast agent (coronary section). CC, corpus cavernosum; T, testicle.
