Primary intracerebral haemorrhage (ICH) refers to spontaneous bleeding from intraparenchymal vessels. It accounts for 10-20% of all strokes, with higher incidence rates amongst African and Asian populations. The major risk factors are hypertension and age. In addition to focal neurological findings, patients may present with symptoms of elevated intracranial pressure. The diagnosis of ICH can only be made through neuro-imaging. A CT scan is presently standard, although MRI is increasingly important in the evaluation of acute cerebrovascular disease. A significant proportion of intracerebral haematomas expand in the first hours post-ictus and this is often associated with clinical worsening. There is evidence that the peri-haematomal region is compromised in ICH. This tissue is oedematous, although the precise pathogenesis is controversial. An association between elevated arterial pressure and haematoma expansion has been reported. Although current guidelines recommend conservative management of arterial pressure in ICH, an acute blood pressure lowering trial is overdue. ICH is associated with a high early mortality rate, although a significant number of survivors make a functional recovery. Current medical management is primarily aimed at prevention of complications including pneumonia and peripheral venous thromboembolism. Elevated intracranial pressure may be treated medically or surgically. Although the latter definitively lowers elevated intracranial pressure, the optimal patient selection criteria are not clear. Aggressive treatment of hypertension is essential in the primary and secondary prevention of ICH.

Background And Objective: Neurobrucellosis is a rare neurological disorder characterized by diverse clinical manifestations. Although several relevant cases were reported, our understanding of this disorder is limited. In this study, we presented the clinical and imaging characteristics of four cases of neurobrucellosis.

Introduction: Positive end-expiratory pressure (PEEP) and prone positioning can improve gas exchange by promoting uniform lung aeration. However, elevated ventilation pressures may increase intracranial pressure (ICP) and disrupt cerebral autoregulation. This study investigated the effects of PEEP on ICP and cerebral autoregulation in a porcine model with healthy lungs and normal ICP, comparing prone and supine positions.

Although there is a large body of existing research on traumatic intracranial hemorrhage, there are few clear and consistent recommendations that have emerged. Appropriate management is guided by an understanding of the pathophysiology of traumatic brain injury as well as by clinical observation and radiographic assessment. This review provides a comprehensive analysis of the literature and recommendations based on the best available evidence, including expeditious management of critically elevated intracranial pressure and acquisition of follow-up studies.

Cerebral proliferative angiopathy (CPA) is a rare subtype of cerebral arteriovenous malformation, characterized by unique angiographic features and clinical presentations. Although the clinical and angiographic characteristics of CPA have been well described, their impact on the surrounding tissues remains underexplored. Herein, we investigated the presence of calvarial thickening in patients with CPA, and discuss its potential pathogenesis.

Background: External ventricular drains (EVDs) provide an invaluable diagnostic method for accessing cerebrospinal fluid and therapeutically treating elevated intracranial pressure. Although complications including hemorrhage and infection have been well documented, the formation of iatrogenic pseudoaneurysms following EVD placement has rarely been reported. The authors present a case of this exceedingly rare complication of iatrogenic pseudoaneurysm formation following EVD placement.
