Effective treatment of intracranial hypertension involves meticulous avoidance of factors that precipitate or aggravate increased intracranial pressure. When intracranial pressure becomes elevated, it is important to rule out new mass lesions that should be surgically evacuated. medical management of increased intracranial pressure should include sedation and paralysis, drainage of cerebrospina...
BACKGROUND The Totaled Health Risks in Vascular Events (THRIVE) score is a clinical prediction score that predicts ischemic stroke outcomes in patients receiving intravenous tissue plasminogen activator, endovascular stroke treatment, or no acute therapy. We have previously found an association between THRIVE and risk of post-tissue plasminogen activator symptomatic intracranial hemorrhage in t...
BACKGROUND AND PURPOSE Atherosclerosis is a systemic disease, and both coronary and intracranial atherosclerosis are common in the elderly. Unlike coronary artery disease (CAD), intracranial atherosclerotic disease can cause intracranial atherosclerotic stroke by branch occlusive disease (B-type) and coronary-type rupture of plaque (C-type). We hypothesized that plaque characteristics of intrac...
Background: Intracranial lipomas are rare benign neoplasms that comprise 1% of all primary brain tumors. Generally, occur in midline structure and usually identified incidentally on CT scans or in autopsies. The incidence of intracranial lipomas is about 0.08 to 0.46% on autopsies. These benign lesions are slow-growing, usually asymptomatic and rarely require surgery. Case Presentation: We r...
Intracranial hypertension is a common final pathway in many acute neurological conditions. However, the cerebral haemodynamic response to acute intracranial hypertension is poorly understood. We assessed cerebral haemodynamics (arterial blood pressure, intracranial pressure, laser Doppler flowmetry, basilar artery Doppler flow velocity, and vascular wall tension) in 27 basilar artery-dependent ...
Intracranial Tuberculoma is a rare form of Tuberculosis (Tb) with presentation of multiple space occupying lesions. Clinical manifestations of intracranial Tuberculoma are dependent to the site of involvement. MRI, positive smear and the evidences of other organs infection can help us to diagnose intracranial Tb. We should consider tuberculosis in patients with unusual presentations even when p...
Background: The diagnosis of acute bacterial meningitis rests on CSF examination by lumbar puncture. Before lumbar puncture, intracranial mass lesions that increase intracranial pressure, must be ruled out, so brain CT-scan may be considered . In this study we evaluated the accuracy of physical examination for intracranial mass in patients with meningismus. Materials and Methods: 100 patients ...
BACKGROUND Transcranial Doppler ultrasound examination (TCD) is a rapid, noninvasive technique used to evaluate cerebral blood flow and is useful for the detection of intracranial hypertension in humans. However, the clinical usefulness of TCD in diagnosing intracranial hypertension has not been demonstrated for intracranial diseases in dogs. OBJECTIVES To determine the association between th...
OBJECTIVES The aim of the present study is to determine if the delineation of one or two optimally chosen intracranial areas (ICA) is enough to achieve adequate estimates of intracranial volume (ICV) in magnetic resonance imaging. METHODS The correlations of 62 fully delineated ICVs with four types of ICV estimates were calculated. The estimate types were: (1) a single midsagittal ICA, (2) si...
