Case Discussion
Case of osteochondroma.
This tumor can present at any age.
It accounts for 10% of all bone tumors and 20% of benign bone tumors.
MRI clearly demonstrates continuity of the exostotic cortex and medullary cavity with that of the parent bone, a hallmark of osteochondromas 1.
Differential diagnosis:
- ossifying hematoma
- juxtacortical chondroma
