Serial imaging of the patient with pelvic chondrosarcoma. Baseline Radiograph of 2014 a showed permeative lytic destruction of left ischium with associated soft tissue component showing chondroid pattern of matrix mineralization. Corroborative MRI b showed similar findings with hyperintense mass (Asterisk) displacing the pelvic structures, not extending to hip joint. In December 2016, patient developed lung and bone metastases (arrow in c, d) after which patient was put on Trabectedin. These lesions remained stable on Trabectedin till December 2017 (e, f). CT images of January 2018 showed progression in form of appearance of new lesions in lung and bone (arrows in g, h). The disease progressed further with appearance of new lung lesions in August 2018 (arrow in i) and at local site in October 2018 (arrow in j)
