ROLE OF MAGNETIC RESONANCE IMAGING IN DIAGNOSIS OF IDIOPATHIC INTRACRANIAL HYPERTENSION

Abstract

Idiopathic intracranial hypertension (IIH) is a disorder of unknown cause that results in increased intracranial pressure without localizing neurologic findings .Brain imaging using MRI is important to exclude any mass occupying lesion or dural sinus thrombosis.MRI features of IIH include elevation of the optic nerve head, empty sellaturcica ,distention of the peri-optic subarachnoid space, tortuosity of the optic nerves, flattening of the posterior sclera of the globe, and dural venous sinus stenosis.AIM OF THE WORK:This study was conducted to study the role of MRI in diagnosis of benign intracranial hypertension.PATIENTS AND METHODSPATIENTS:This study was carried out on 20 patients with symptoms of intracranial hypertension referred to the Radio-diagnosis Department, Main University Hospital, Alexandria University from November 2019 to November 2020.METHODS:The studied patients were subjected to the following:Detailed history taking and thorough clinical examination.Imaging evaluation of the brain including :Routine magnetic resonance imaging sequences including 3D T1, axial, sagittal and coronal T2, axial FLAIR.T1 Weighted post contrast axial images if needed.MRV if needed to visualize dural venous stenosis or thrombosis
