Thanks to everyone who gave me their opinions, for the more focused, it was indeed the crest of the scapula and not the clavicle.
here is a list of all the answers i had:
-Osteoid osteoma: 4
-Lesion of Dergon (which i’ve never heard of): 1
-Hemangioma with sclerosis, OT-RADS II: 1
-Fibrous dysplasia or benign fibro-osseous lesion: 1
I had more informations in the meantime, patient also have rotator cuff damage, and the pain is more diffuse in the trapezius muscle region.
I recon this could be an incidental finding that has nothing to do with the pain.
Thanks to all!
