Idiopathic inflammatory perioptic neuritis simulating optic nerve sheath meningioma
American Journal of Ophthalmology
|September 15, 1985
Summary
Idiopathic inflammatory perioptic neuritis can mimic optic nerve sheath meningioma, causing visual loss and nerve enlargement. Biopsy is crucial for accurate diagnosis, distinguishing inflammation from actual tumors.
Area of Science:
- Ophthalmology
- Neurology
- Pathology
Background:
- Optic nerve sheath meningioma diagnosis often relies on clinical and imaging findings.
- Distinguishing meningiomas from other optic nerve pathologies can be challenging.
Observation:
- 13 patients with suspected optic nerve sheath meningioma presented with visual loss and nerve enlargement.
- Imaging studies confirmed optic nerve or sheath enlargement in all cases.
- Surgical biopsies were performed for definitive diagnosis.
Findings:
- Histological examination revealed meningioma in 9 out of 13 patients.
- Four patients lacked meningioma; two had inflammatory infiltration, two had fibrous tissue.
- No systemic diseases were identified as a cause.
Implications:
- Optic nerve sheath enlargement may result from idiopathic inflammatory perioptic neuritis, simulating meningioma.
- Accurate diagnosis necessitates histological confirmation via biopsy.
- This highlights the importance of biopsy in differentiating inflammatory conditions from tumors affecting the optic nerve sheath.
