Magnetic resonance imaging (MRI) scans of pelvis demonstrating a soft tissue mass, which shows isointense signal intensity on T1W images (Fig. 3a) and inhomogeneous high signal intensity on T2W images (Fig. 3b.e) and STIR images (Fig. 3c) compared with the surrounding muscles. Gadolinium-enhanced fat-suppressed T1-weighted images (Fig. 3d.f) shows slightly inhomogeneous enhancement
