Orbital osteosarcoma metastasis is rare and can cause severe vision loss. Combined treatments offer partial symptom relief but do not fully eliminate the tumor, impacting vision long-term.

Area of Science:

  • Oncology
  • Ophthalmology
  • Radiology

Background:

  • Osteosarcoma, a primary bone cancer, rarely metastasizes to the orbit.
  • Orbital metastasis can lead to significant visual impairment and proptosis.

Observation:

  • A 15-year-old presented with orbital and skull base metastases from tibial osteosarcoma.
  • Symptoms included painful proptosis and severe visual decline, progressing to no light perception post-embolization.

Findings:

  • Multimodal treatment (embolization, radiotherapy, chemotherapy, surgery) partially restored vision to counting fingers.
  • Histopathology confirmed necrotic tumor consistent with osteosarcoma.
  • Vision remained stable but impaired at 24-month follow-up.

Implications:

  • Orbital osteosarcoma metastasis is a rare but serious complication.
  • Combined therapy can alleviate symptoms but has limitations in tumor eradication.
  • This case highlights the challenges in managing rare metastatic orbital tumors and preserving vision.
