Area of Science:

  • Orthopedic Oncology
  • Skeletal Radiology
  • Bone Pathology

Background:

  • Osteosarcoma is the most frequent primary bone malignancy in adolescents and young adults.
  • It represents about 15% of all bone tumors diagnosed via biopsy.
  • Classified into intramedullary, surface, and extraskeletal types, it can also arise secondary to benign conditions.

Purpose of the Study:

  • To review the diverse subtypes of osteosarcoma.
  • To emphasize the importance of recognizing variable radiologic appearances.
  • To highlight the role of imaging in diagnosis and management.

Main Methods:

  • Review of osteosarcoma classification and imaging characteristics.
  • Discussion of diagnostic modalities including radiography, CT, and MRI.

  • Emphasis on the correlation between imaging findings and pathological features.

    • Main Results:

    • Osteosarcoma exhibits numerous subtypes with distinct intramedullary, surface, and extraskeletal presentations.
    • Radiographic assessment is crucial for differential diagnosis.
    • CT and MRI are essential for staging and treatment planning.

    Conclusions:

    • Accurate identification of osteosarcoma subtypes through understanding variable imaging appearances is vital.
    • Optimal clinical management, including diagnosis, biopsy, staging, treatment, and follow-up, relies on comprehensive radiologic assessment.
    • Improved recognition of diverse osteosarcoma presentations enhances patient care and outcomes.
