Chondrosarcoma is a malignant cartilage-forming tumour accounting for 8–17% of all biopsied primary bone tumours and 20–25% of all biopsied malignant bone tumours. It is classified as central if arising within medullary bone and peripheral if arising from the surface of bone. A30-year male presented with hard swelling and pain in the left shoulder region for 6 months. X-ray showed a well-defined lytic lesion in the proximal part of the humerus with chondroid matrix calcificationas ring-and-arc. Confirmation of the findings was done on CT scan. MRI shows a typical hyperintense multi-lobular pattern on fluid-sensitive sequences (T2 WI) with low signal intensity foci representing chondroid calcification on all pulse sequences. Radiological diagnosis was confirmed on histopathology.
