Abstract Purpose of Review Idiopathic intracranial hypertension (IIH) is a disorder
characterized by long-standing elevated intracranial pressure (ICP). As the name applies …

BACKGROUND AND PURPOSE: Large arachnoid granulations (AG) within the dorsal
superior sagittal sinus (SSS) have been incompletely characterized and can be confused …

“Giant” AGs (> 1 cm) are uncommon and can be misdiagnosed as venous sinus pathology
such as a neoplasm or thrombosis. Seventeen patients with a total of 19 venous sinus AGs …

Objectives To determine frequency, imaging features and clinical significance of herniations
of brain parenchyma into dural venous sinuses (DVS) and/or calvarium found on MRI …

Background: Dural and bony defects formed by AGs are proposed to lead to spontaneous
meningoencephaloceles and cerebrospinal fluid otorrhea. They most commonly occur at the …

Giant arachnoid granulations (GAGs) are minimally investigated. Here, we systematically
review the available data in published reports to better understand their etiologies …

The authors describe a patient with pseudotumor cerebri syndrome who showed at
venography a giant arachnoid granulation in the left dominant transverse sinus and …

Brain herniations into dural venous sinuses (DVS) are rare findings recently described and
their etiology and clinical significance are controversial. We describe five patients with brain …

ABSTRACT BACKGROUND/PURPOSE Brain herniation into presumed arachnoid
granulations (BHAG) is an increasingly recognized entity. Though it has previously been …

Background Leptomeningeal metastasis (LM) is an uncommon, but devastating
complication of advanced cancer and has no standard treatment. Herein, we analyzed the …
