Diagnosis: Osteosarcoma

Findings on Imaging:

  • X-ray of the right tibia shows a subtle yet destructive lesion involving the distal tibial metaphysis with areas of calcification and cortical destruction.
  • The lesion has a spiculated appearance with periosteal reaction, suggestive of an aggressive bone tumor.

Next Steps in Management:

  • The patient should undergo further evaluation to determine the extent and stage of the osteosarcoma.
  • Treatment typically involves a combination of chemotherapy and surgery, with the goal of achieving local control of the tumor and preventing distant metastases.
  • In cases of localized osteosarcoma, limb salvage surgery is typically performed.

Key Take Away Points:

  • Osteosarcoma is an aggressive bone tumor that typically presents as a destructive lesion with calcification and cortical destruction on imaging.
  • The goal of treatment is to achieve local control of the tumor and prevent distant metastases, and typically involves a combination of chemotherapy and surgery.
  • In cases of localized osteosarcoma, limb salvage surgery is typically performed.
  • Early diagnosis and treatment can improve outcomes for patients with osteosarcoma.
