(a) The lesion demonstrated well-defined low signal intensity on axial T1 weighted imaging, time of repetition/time of echo (TR/TE): 579/10; (b) heterogeneously high signal intensity on STIR axial imaging, TR/TE: 3579/60 and (c) enhancement at the margin on axial T1 weighted imaging after injection of diethylenetriamine-pentaacetic acid (Gd-DTPA), TR/TE: 545/10
