Left distal femoral diametaphyseal eccentric low T1W signal lesion, with some mixed T2W signal. No cortical disruption, associated soft tissue component or periosteal reaction.

Case Discussion

Plain x-ray and MRI appearances of non-ossifying fibroma, which are important to recognise as this is a "do not touch" bone lesion that does not require biopsy.
