Cerebral venous etiology of intracranial hypertension and differentiation from idiopathic intracranial hypertension.
This study presents the characteristics that distinguish between idiopathic intracranial hypertension (ICH) and ICH caused by intracranial vascular damage. Twenty-one patients with ICH were included in this study. The analysis of the symptomatology correlated with the values of intracranial pressure, and the imaging findings revealed significant differences between these two types of ICH. ICH caused by intracranial venous vascular damage is named vascular ICH. Vascular ICH has a known etiology, such as cerebral vascular illness, and a relatively rapid increase in intracranial pressure of approximately 21 cmH2O and imaging findings show characteristic images of thrombosis or stenosis of the intracranial venous system, while all brain images (computed tomography, magnetic resonance imaging, angio-magnetic resonance imaging) are normal in idiopathic ICH. The treatment of vascular ICH is etiologic, pathogenic, and symptomatic, but that of idiopathic ICH is only symptomatic.
