There is a lesion from the mid-distal diaphysis and metaphyseal region of the left femur. The lesion is mainly hypoechoic ( non-ossified bone ) with new bone formation perpendicular to bone cortex; resulting in a 'sunburst appearance'. The approximate craniocaudal extension is 10 cm.
Quadriceps muscles - tendon are displaced by the lesion. There is no effusion in the suprapatellar recess of knee.
