A 14-year-old male patient with right thigh pleomorphic liposarcoma. Contrast-enhanced T1-weighted images at baseline, 10 and 18 weeks after chemotherapy (a–c) revealing initially heterogeneous moderately enhancing tumor with size progression and reduction in the tissue contrast enhancement in follow up studies. As compared to the initial MRI study, the tumor showed about (89%) increase in size classified as PD according to RECIST 1.1; however, it showed (45%) reduction in size which is classified as PR according to mRECIST. ADC images at baseline, after 10 weeks of chemotherapy and after 18 weeks (d–f) showing an evident increase in ADC values denoting therapeutic response. Wide local excision and the post-operative pathology report showed wide areas of necrosis & tumor viability is about 40%
