Study Notes
Bone Tumors in Adolescents and Young Adults
- Osteosarcoma is commonly associated with adolescents and young adults, frequently occurring in the metaphysis of long bones such as the femur and tibia.
Radiographic Appearance of Osteoid Osteoma
- Osteoid osteoma typically presents with a characteristic "nidus," a small, round radiolucency surrounded by a dense area of reactive bone formation on imaging.
Diagnosis for Distal Femur Pain
- A 'sunburst' appearance on imaging suggests osteosarcoma, especially in a patient presenting with pain, swelling, and a palpable mass in the distal femur.
Cartilage-Forming Tumor
- Chondrosarcoma is a cartilage-forming tumor that arises in the medullary cavity of long bones and usually affects individuals over 40 years of age.
Benign Bone Tumor of Well-Differentiated Cartilage
- An enchondroma is a benign bone tumor composed of well-differentiated cartilage, often found in the hands and feet.
