Summary
Neurofibromatosis type 2 can cause pseudopapilledema due to epiretinal membranes. This case highlights the importance of considering pseudopapilledema in NF2 patients with optic nerve abnormalities.
Area of Science:
- Ophthalmology
- Neuro-oncology
- Genetics
Background:
- Neurofibromatosis type 2 (NF2) is a genetic disorder characterized by the development of tumors in the nervous system.
- Optic nerve abnormalities can occur in NF2 patients, necessitating careful differential diagnosis.
Observation:
- A 14-year-old male with NF2 presented with fundus examination findings suggestive of optic nerve elevation in the right eye.
- A perifoveal epiretinal membrane was noted overlying the optic disc.
Findings:
- Ocular examination revealed irregular optic nerve elevation and a prepapillary epiretinal membrane.
- Fluorescein angiography showed no abnormal autofluorescence or leakage, ruling out optic disc edema.
Implications:
- This case illustrates pseudopapilledema as a manifestation of NF2, secondary to a prepapillary gliotic membrane.
- Clinicians should consider pseudopapilledema in the differential diagnosis of optic nerve abnormalities in patients with NF2.
