    A rare optic nerve hemangioblastoma was diagnosed in a male patient with a family history of brain tumors. This supratentorial tumor presented with vision loss and eye protrusion.

    Area of Science:

    • Neuro-oncology
    • Ophthalmology
    • Vascular Tumors

    Background:

    • Hemangioblastomas are typically found in the posterior fossa.
    • Optic nerve hemangioblastomas are exceptionally rare supratentorial tumors.
    • These tumors often have a familial association.

    Observation:

    • A 36-year-old male presented with visual loss and exophthalmos.
    • Imaging revealed a hypervascular tumor at the orbital apex involving the optic nerve.
    • Histopathology confirmed a characteristic hemangioblastoma.

    Findings:

    • A solitary hemangioblastoma of the optic nerve was surgically resected.
    • The tumor was supplied by the ophthalmic artery.
    • The optic nerve was enlarged and encased by the tumor.

    Implications:

    • This case highlights the rarity of supratentorial hemangioblastomas.
    • Early diagnosis and surgical intervention are crucial for vision preservation.
    • Understanding the familial nature is important for genetic counseling and screening.
