A 15-year-old male patient, presenting with right leg recurrent undifferentiated spindle cell sarcoma. Contrast-enhanced T1-weighted images at baseline (a) revealing a strongly and almost homogeneously enhancing tumor in the posterior compartment of the right leg with the 3 months follow up images (b) after CCRTH shows marked reduction of tumor size and contrast enhancement. The tumor showed about (36%) decrease in size which is classified as PR according to RECIST 1.1 and no residual enhancement classified as CR according to m RECIST. ADC images at baseline and after 3 months of CCRT (c, d) showing facilitated diffusion and increased mean ADC value. Wide local excision of the mass showed no evidence of malignancy denoting good therapeutic response matching both m RECIST and ADC
