Summary
Optic nerve sheath meningiomas are rare orbital tumors, primarily affecting adult women. Visual loss is the initial symptom, with surgical intervention being the standard treatment for these optic nerve tumors.
Area of Science:
- Ophthalmology
- Neurology
- Oncology
Background:
- Meningiomas originating from the optic nerve sheath are uncommon orbital tumors.
- This study analyzes a series of 15 such cases within a larger cohort of orbital neoplasms.
Purpose of the Study:
- To describe the clinical presentation, diagnostic imaging, and management of optic nerve sheath meningiomas.
- To highlight the key features distinguishing these tumors from other orbital pathologies.
Main Methods:
- Retrospective analysis of 15 patients diagnosed with optic nerve sheath meningiomas.
- Review of clinical data, including symptoms, signs, and treatment outcomes.
- Evaluation of imaging modalities such as EMI scanner and c-mode ultrasonography.
Main Results:
- The cohort consisted of 15 patients, predominantly adult women (11/15), with only one child.
- Visual loss was the most common initial symptom (15/15), followed by proptosis in ten patients.
- All patients exhibited optic disc edema or atrophy; some presented with optociliary shunt vessels.
- Both EMI scanner and c-mode ultrasonography visualized the tumors, with ultrasonography providing clearer detail.
Conclusions:
- Optic nerve sheath meningiomas present with characteristic visual disturbances and funduscopic findings.
- Advanced imaging techniques aid in the diagnosis of these orbital tumors.
- Surgical resection remains the primary treatment modality for optic nerve sheath meningiomas.
