Papilledema and diplopia due to meningioma inside the superior sagittal sinus: A case report and review of the literature

Abstract

Introduction: Small lesions involving or compressing dural sinuses are frequent but secondary intracranial hypertension is not very common, with few examples reported in the literature. This event may be explained in the setting of anatomic variants in pattern of venous sinus circulation. Case Report: We present the case of a patient who presented with papilledema and loss of visual acuity due to a small meningioma located inside the superior sagittal sinus (SSS). The patient underwent a lumboperitoneal (LP) shunt placement with recovery of symptoms. Available literature is also reviewed. Conclusion: Intracranial hypertension secondary to a meningioma located in the SSS is an uncommon entity. In its management, cerebrospinal fluid (CSF) shunts should be considered for symptomatic management. The definitive treatment may be targeted depending on multiple factors taking into account risk and benefit.
