An 18-year-old female patient with a voluminous lesion in the left hemi-pelvis (a, arrow) and histologically confirmed chondrosarcoma underwent whole-body MRI with a coronal STIR sequence for staging. The examination revealed involvement in the sacrum (a, arrow) and left ilium (b, arrow) and the presence of soft-tissue components adjacent to marked hyperintensity (c, arrow). Note the antalgic position, with slight body deviation to the right. No other lesion suspicious of malignancy was noted
