ObjectiveMany but not all patients with idiopathic intracranial hypertension (IIH) have pulsatile tinnitus (PT). However, little is known about why some patients with IIH develop PT and others do not. The purpose of this study was to determine if any of the classic magnetic resonance imaging ...
The initial evaluation of acute intracranial hypertension should include a head CT. Cerebral edema-associated CT scan findings indicating intracranial hypertension include compressed basal cisterns, herniation patterns, cortical sulcal effacement, and midline shift. However, the absence of these findings does...

What is idiopathic intracranial hypertension (IIH)?IIH is a condition that causes the pressure inside your skull to be higher than normal for no known reason. IIH can seem like a brain tumor, but no tumor is found.What causes IIH?
Hypertension Systemic hypertension remains the leading cause of spontaneous intra-axial hemorrhage in adults5 (Fig. 3), with a predilection for the deep gray nuclei, capsular structures, cerebellum, and pons. The lobar cerebral white matter may also be involved. Common associated imaging findings inc...
特发性颅高压(Idiopathic Intracranial Hypertension,IIH)是一种临床综合征,也称大脑假瘤、良性颅内压增高等,为不明原因导致的脑脊液分泌-吸收失衡引起。患者多为育龄、较肥胖女性,近期体重有急剧增加。男性患者中鼾症是另一个相关因素。除此之外,长期服用维生素A、四环素及环孢素类药物也是重要的病因。我们发现,多囊卵...
We reviewed the CT scan and MRI (T1WI before and after gadolinium injection, T2WI, proton density and angio-MR) for three patients. Brain angiography was available for two patients. Results. The patients were aged 37 to 60 years, and were essentially admitted for intracranial hypertension. ...
MRI findingsPurposeTo search for CSF dynamics of idiopathic intracranial hypertension (IIH) and communicating hydrocephalus and any correlation between MRI findings, CSF metrics and CSF opening pressure in IIH.Materials and methodsHealthy subjects (30) and subjects with IIH (29) and high-pressure ...
