[Cartilage tumors : Pathology and radiomorphology]

Area of Science:

• Skeletal Radiology
• Bone Pathology
• Oncology

Background:

• Primary cartilage-forming bone tumors are common in skeletal radiology.
• Accurate differentiation between benign and malignant lesions is crucial for patient management.

Purpose of the Study:

• To correlate pathological features of cartilage tumors with their radiological appearance on various imaging modalities.
• To enhance radiologists' ability to diagnose cartilage tumors based on imaging patterns.

Main Methods:

• Review of pathological and radiological features of common cartilage-forming bone tumors.
• Correlation of radiographic, CT, and MRI findings with histopathological diagnoses.
• Identification of imaging parameters indicative of malignancy.

Main Results:

• Specific imaging characteristics are associated with enchondroma, osteochondroma, chondroblastoma, and chondrosarcoma.
• Imaging features like deep cortical scalloping, destruction, and soft tissue mass suggest malignancy.
• Osteochondromas exhibit characteristic bony protrusions with cartilage caps.
• Chondroblastomas show epiphyseal predilection and bone marrow edema.
• Dedifferentiated chondrosarcomas present as bimorphic lesions.

Conclusions:

• Radiological assessment, guided by pathological correlation, is essential for diagnosing cartilage-forming bone tumors.
• Distinguishing between enchondroma and chondrosarcoma remains a diagnostic challenge, with specific imaging findings aiding differentiation.
• Understanding tumor site and age predilections improves diagnostic accuracy.
