2025年3月19日 · CT/MRI. Imaging of the brain with CT or MRI without and with contrast, and possibly CT or MR venography, is essential in patients with suspected idiopathic intracranial hypertension to exclude elevated CSF pressure due to other causes such as brain tumor, dural sinus thrombosis, hydrocephalus, etc.

There are a few signs that are non-specific but in combination can be seen in idiopathic intracranial hypertension. The transverse and sigmoid sinuses are narrowed however no thrombosis is identified within them. The left side is slightly dominant. The superior sagittal sinus is normal. No cortical vein thrombosis evident. Conclusion.

In this review, we discuss the multiple modalities for imaging IIH, their limitations, and their contributions to the management of IIH. Increased intracranial pressure (IICP) can be caused by mass lesions, impaired venous drainage, increased cerebrospinal fluid (CSF) production or decreased reabsorption.

Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a syndrome characterized by increased intracranial pressure of unknown cause 1-5. It predominantly affects overweight women of childbearing age 2,3. The yearly incidence of IIH is …

In patients suspected of having IIH without papilledema or in whom established optic atrophy prevents disc swelling, OCT systems can be used to obtain motion-stabilized laser ophthalmoscopic videos, which are extremely sensitive in detecting spontaneous retinal venous pulsation (SVP) .

Coronal thin section computed tomography (CT) shows a bony defect of the right anterior ethmoid roof (arrow) in an untreated IIH patient with opacification of the ipsilateral ethmoid air cells. B . 3D reconstruction, endocranial view of same patient as ( A ), demonstrates the bony defect (arrow).

2022年2月1日 · CT/CTV signs exhibited a sensitivity of 61.0% and specificity of 100.0% for IIH. The diagnostic utility of neuroradiologic signs associated with idiopathic intracranial hypertension (IIH) for the evaluation of patients presenting with papilloedema remains yet to be elucidated.

1994年2月1日 · IIH is a recognized cause of reversible vision loss in adult obese women. The diagnosis of IIH requires a documented elevation of intracranial pressure, normal cerebrospinal fluid (CSF) composition, and normal findings on neuroimaging studies.

Idiopathic intracranial hypertension (IIH) is a challenging disorder with a rapid increasing incidence due to a close relation to obesity. The onset of symptoms is often insidious and patients may see many different specialists before the IIH diagnosis is settled.

2021年12月21日 · Idiopathic intracranial hypertension (IIH) is characterized by increased intracranial pressure, manifested by papilledema and radiological findings, in the absence of an identifiable casual factor. The primary symptoms include headache, vision loss, and pulsatile tinnitus, and are recognized to have …
