The lateral Xray of the knee shows a sclerotic lesion in the metaphyseal region of the proximal tibia. The lesion is poorly demarcated. There is mineralisation anteriorly in the anterior soft tissues.
The MRI on the previous page shows the marked extension of this malignant tumour into the medial soft tissues. The raylike appearance of this soft tissue signal is the Magnetic resonance equivalent of a sunray appearance on straight Xrays.
