Hi OCADers,
What is your differential diagnosis of the lesion in the posterior medial femoral condyle showing some cortical irregularities? I think it looks worse on the coronals than it actually is because of the plane of scanning. Besides a do-not-touch Cortical Desmoid lesion, would you entertain any other possibility? There’s thickening at the insertion of the medial head of the gastrocnemius tendon (which also goes along with a cortical avulsive injury). Should it be followed up?
Thank you,

Leave it alone. It’s a tug lesion.
Don’t call it a “cortical desmoid”. Desmoids are tumors. This is not neoplastic. Bad name that should be deleted from our lexicon!
