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
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
