This study reports the first case of bilateral orbital metastasis and papilledema from Ewing sarcoma, linked to hypercoagulability. The findings highlight a rare presentation of advanced cancer impacting vision.
Area of Science:
- Oncology
- Ophthalmology
- Neurology
Background:
- Ewing sarcoma is a rare bone and soft tissue cancer.
- Metastatic spread of Ewing sarcoma can affect various organs.
- Hypercoagulability is an increased risk of blood clot formation.
Observation:
- A 39-year-old woman with known spinal Ewing sarcoma and lung metastases developed decreased visual acuity.
- Ophthalmic examination revealed bilateral disc edema.
- Brain and orbital MRI demonstrated metastatic dural and orbital lesions, along with venous sinus thrombosis.
Findings:
- This case presents bilateral orbital metastasis and papilledema as a direct consequence of Ewing sarcoma.
- The patient's condition was associated with venous sinus thrombosis, suggesting a hypercoagulable state.
- This represents the first documented instance of these specific ophthalmic and neurological complications secondary to Ewing sarcoma.
Implications:
- This case underscores the importance of thorough ophthalmic and neurological evaluation in patients with advanced Ewing sarcoma.
- It highlights a potential link between Ewing sarcoma, hypercoagulability, and secondary orbital and intracranial complications.
- Further research may elucidate the mechanisms of hypercoagulability in Ewing sarcoma and its impact on metastatic patterns.
