Increased intracranial pressure may produce a variety of clinical manifestations, some common and others rare. We present a patient with idiopathic intracranial hypertension whose initial symptom was hemifacial spasm. All signs and symptoms of intracranial hypertension resolved with acetazolamide.

Rupture of an intracranial aneurysm is a life-threatening event. Only one third of intracranial aneurysms rupture during a patient's lifetime. Accurate markers that predict which intracranial aneurysms rupture and which do not are currently lacking in routine clinical practice. Therefore, the treatment decision is a careful balance between the natural history of the intracranial aneurysm and th...

BACKGROUND AND PURPOSE Saccular intracranial aneurysm is a common disease that may cause devastating intracranial hemorrhage. Hemodynamics, wall remodeling, and wall inflammation have been associated with saccular intracranial aneurysm rupture. We investigated how saccular intracranial aneurysm hemodynamics is associated with wall remodeling and inflammation of the saccular intracranial aneurys...

BACKGROUND Intracranial atherosclerosis is a leading cause of stroke, but little is known about the composition of the intracranial atherosclerotic lesion and how intracranial plaque morphology is related to the risk of stroke. High-resolution magnetic resonance imaging (HR MRI) has been used in patients with extracranial carotid atherosclerosis as an in vivo tool to identify, with high-interra...

OBJECTIVE To determine whether there was a correlation between tonometric measurements of the intraocular pressure and transducer measurements of the intracranial pressure in the acute setting, and whether intraocular pressure can be used as a surrogate measure of intracranial pressure. Children with traumatic brain injuries commonly develop increased intracranial pressure requiring surgical pl...

Subarachnoid hemorrhage (SAH) is bleeding into the subarachnoid space. It may result from a rupture of an intracranial aneurysm, bleeding from an arteriovenous malformation, hypertensive intracerebral hemorrhage with extension into the subarachnoid space, hemorrhage from an intracranial tumor, trauma, and hematologic disorders. If trauma is eliminated as a cause of SAH, more than 80% of SAHs ar...

Elevated intracranial intravenous pressure seems to be of importance in pseudotumor cerebri syndromes, either as a cause (secondary intracranial hypertension) or as a consequence (idiopathic intracranial hypertension) of increased intracranial pressure. We present 3 case reports in which diagnostic imaging before and after CSF diversion provided evidence that narrowing of the transverse sinuses...

Mechanical heart valves are associated with a risk of thromboembolism and anticoagulation is generally recommended. However, this is inevitably associated with a risk of intracranial bleeding. The case of a patient who sustained an intracranial bleed while taking warfarin for a prosthetic aortic valve and a further two intracranial bleeds while on heparin as an inpatient is discussed and the li...

background & importance: the use of local hemostatic agents in neurosurgery is mandatory in order to control the sequelae of intracerebal hemorrhage. it is widely used in oxidized regenerated cellulose (surgicel™). case presentation: a 54-year-old man previously operated for grade ii meningioma came back to our attention due to the onset of left side arm weakness one month after surgery. the ct...

One of the main limitations of intracranial models of diseases is our present inability to monitor and evaluate the intracranial compartment noninvasively over time. Therefore, there is a growing need for imaging modalities that provide thorough neuropathological evaluations of xenograft and transgenic models of intracranial pathology. In this study, we have established protocols for multiple-m...
