Rather well-defined sessile bony out-growth is seen at the lateral aspect of the lower third left femur. It shows continuity with the cortex and medullary cavity of the parent bone. There are overlying soft tissue oedema and inflammatory changes which appear bright in T2 and of low signal in T1.
There is also another bony lesion in the posterolateral aspect of the left femur lower third at the same level of the bony out growth projection, having bubbly appearance and showing low signal in all sequences, sclerotic margin as well as narrow transitional zone .
