Papilledema and dural sinus obstruction.

M X Repka, N R Miller

    Journal of Clinical Neuro-Ophthalmology
    |December 1, 1984

    Summary
    This summary is machine-generated.

    Meningiomas can block the posterior sagittal sinus, leading to increased intracranial pressure and vision loss. Early recognition is crucial to prevent irreversible optic atrophy and visual impairment.

    Area of Science:

    • Neurosurgery
    • Neurology
    • Ophthalmology

    Background:

    • Posterior sagittal sinus meningiomas are rare tumors.
    • Cerebral venous drainage is critical for maintaining normal intracranial pressure.

    Observation:

    • Two cases presented with meningioma obstructing the posterior sagittal sinus.
    • Patients developed elevated intracranial pressure and papilledema due to impaired venous drainage.

    Findings:

    • The obstructive mechanism was not identified preoperatively in either case.
    • Both patients suffered optic atrophy and significant visual loss as a consequence.

    Implications:

    • Highlights the importance of considering venous obstruction in meningioma diagnosis.
