    This case report details a rare instance of bilateral optic nerve meningioma, a condition affecting both optic nerves. Early symptoms mimicked optic neuritis, progressing to vision loss and optic atrophy.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Oncology

    Background:

    • Meningiomas are typically benign tumors arising from the meninges.
    • Optic nerve meningiomas are rare, and bilateral involvement is exceptionally uncommon.
    • This report presents a unique case contributing to the limited literature on this condition.

    Observation:

    • A 27-year-old presented with symptoms resembling unilateral optic neuritis and papilledema.
    • Over 4 years, the condition progressed to bilateral amaurosis (vision loss) and optic atrophy.
    • Radiological findings included a "blistering" bone reaction on skull X-ray, enlarged ophthalmic artery on angiography, and fusiform enlargement of both optic nerves on CT scan.

    Findings:

    • Pathological diagnosis confirmed bilateral optic nerve meningioma via optic nerve biopsy.

  • This represents the 12th reported case of bilateral optic nerve meningioma globally.
  • The diagnostic imaging revealed characteristic bone erosion and tumor encasement of the optic nerves.

    • Implications:

    • Highlights the importance of considering rare diagnoses in cases of progressive optic neuropathy.
    • Emphasizes the utility of advanced imaging techniques in diagnosing optic nerve sheath tumors.
    • Adds valuable data to the understanding and clinical management of bilateral optic nerve meningiomas.
