Seven months later, an MR of right cruris which was done for the investigation of right leg pain showed a contrast-enhancing lesion with a diameter of 3.5 cm located at the subcutaneous area of posterior part of right cruris [Figure 4].
MRI shows a soft tissue lesion in the intermuscular area, with a diameter of 2.5 cm, which is hypointense on T1-weighted images (a) and hyperintense on T2-weighted images (b) and showing intense contrast enhancement
