Study Notes

  • Neoplasms in this category produce chondroid matrix with calcifications.
  • Osteochondroma is the most common benign lesion of bone.
  • Enchondromas and osteochondromas can transform into chondrosarcoma.
  • Periosteal chondromas arise from the cortical surface and can be difficult to distinguish from malignant mimickers.
  • Chondroblastomas occur in skeletally immature patients and arise in the epiphysis.
  • Chondromyxoid fibromas are quite rare and have less specific imaging features.
  • Chondrosarcomas are the third most common primary bone malignancy.
  • They can be divided into primary and secondary chondrosarcomas.
  • Conventional chondrosarcomas are often low grade and most commonly found in the long bones and pelvis.
  • Adequate surgical resection is important for chondrosarcoma treatment.
