A well-defined lesion in the distal metaphysis and extend into the epiphysis of the right femur, which demonstrates hypointense signal in T1 and hyperintense signal in T2/STIR and enhances in the post gadolinium acquisitions. Small cystic component seen, although it does not demonstrate fluid-fluid level, a coexistence small aneurysmal bone cyst component is still possible.
This lesion has expands and has breached the posterior cortex of the distal femur. High T1/T2 signal in the popliteal vein corresponds with a venous thrombosis.
