Overview
Findings on MRI suggestive of chondroma include well circumscribed, lobulated mass replacing the marrow for enchondroma, lobulated soft tissue lesion that is abutting the cortex and evidence of pressure erosion on neighboring bone, with no evidence of medullary bone or soft tissue edema for periostal chondroma for periostal chondroma.
MRI
- Bone MRI may be helpful in the diagnosis of chondroma. Findings on MRI suggestive of chondroma include:[1][2][3]
- Well circumscribed, lobulated mass replacing the marrow for enchondroma
- lobulated soft tissue lesion that is abutting the cortex and evidence of pressure erosion on neighboring bone, with no evidence of medullary bone or soft tissue edema for periostal chondroma for periostal chondroma
