Overview

MRI of the affected bone is helpful in the diagnosis of chondroma. On MRI, enchondroma is characterized by well circumscribed, lobulated mass replacing the bone marrow. On MRI, periosteal chondroma is characterized by lobulated soft tissue lesion, abutting the cortex and may demonstrate evidence of pressure erosion on neighboring bone, with no evidence of medullary bone or soft tissue edema.

MRI

• MRI of the affected bone is helpful in the diagnosis of chondroma.
• On MRI, enchondroma is characterized by well circumscribed, lobulated mass replacing the marrow.
• On MRI, periosteal chondroma is characterized by lobulated soft tissue lesion, abutting the cortex and may demonstrate evidence of pressure erosion on neighboring bone, with no evidence of medullary bone or soft tissue edema.
• Following are the MRI signal characteristics:

MRI component	Enchondroma	Periosteal chondroma
T1	Intermediate to low signal	Iso to low signal relative to muscle
T2	Typically of background intense high signal Focal low signal areas representing calcification No bone marrow or soft tissue oedema	Generally high signal Focal low signal areas representing calcification
T1 with contrast	Enhancement is variable May be seen both peripherally or of translesional septae	Heterogenous Tends to show peripheral predominant contrast enhancement
