Figure 1. (a) Axial T1 weighted image (repetition time (TR)/echo time (TE) = 467/8) showed soft-tissue mass of homogeneous isointensity around the middle to basal part of penis. (b) Sagittal T2 weighted image (TR/TE = 2350/87) showed the extension of the lesion. The capsule of corpus spongiosum is intact. (c) Coronal T1 weighted image (TR/TE = 2650/87) showed the relationship between the mass and the corpus cavernosum and corpus spongiosum. (d) Coronal T1 weighted image after Gd-DTPA demonstrated the mass without obvious enhancement.
