Background: Mucoceles are epithelial lined sacs that contain mucous. Eventually, they can be infected and so called mucopyoceles, which are usually slow growing lesions with common bone destruction located in the facial sinus. Mucoceles show multivariate etiology and occur between the fourth and seventh decade of life. Case Description: Patient, 55-year-old, female, was referred unconscious with Cushing's triad to our department; she had fever since four days. The findings of skull computer tomography highlighted a large bifrontal lesion with an invasion of the rear wall of the frontal sinus, compression of the frontal lobes, and midline deviation...

OBJECTIVE: Decompressive craniectomy (DC) is used to treat intractable intracranial hypertension following severe traumatic brain injury (TBI). Cranioplasty (CP) is typically performed weeks or months later. However, the optimal timing for CP is unknown. We aimed to determine the earliest possible time point for CP. METHODS: We retrospectively reviewed brain computed tomography (CT) images from 159 patients who underwent CP following DC for TBI at 3 hospitals. We determined the earliest possible day for CP by reviewing the resolution of intracranial pressure in serial brain CT images between DC and CP...

Intracranial pressure monitoring devices have become the standard of care for the management of patients with pathologies associated with intracranial hypertension. Given the importance of invasive intracranial monitoring devices in the modern neurointensive care setting, gaining a thorough understanding of the potential complications related to device placement-and misplacement-is crucial. The increased prevalence of intracranial pressure monitoring as a management tool for neurosurgical patients has led to the publication of a plethora of papers regarding their indications and complications...

Intracranial pressure (ICP) monitoring has been widely accepted in the management of traumatic brain injury. However, its use in other pathologies that affect ICP has not been advocated as strongly, especially in CNS infections. Despite the most aggressive and novel antimicrobial therapies for meningitis, the mortality rate associated with this disease is far from satisfactory. Although intracranial hypertension and subsequent death have long been known to complicate meningitis, no specific guidelines targeting ICP monitoring are available...

PURPOSE OF REVIEW: Stroke is common and often presents as a neurologic emergency that requires rapid evaluation and treatment to minimize debilitation. Recent advances in therapy expanded time windows for intra-arterial thrombectomy in ischemic stroke, and surgical interventions for clot evacuation in large intracranial hemorrhage have recently proven feasible. This review discusses recent data regarding new therapeutic options in both ischemic and hemorrhagic stroke, notably in scenarios in which therapy was previously limited to supportive care...

OBJECTIVE Idiopathic intracranial hypertension (IIH) is commonly associated with venous sinus stenosis. In recent years, transvenous dural venous sinus stent (DVSS) insertion has emerged as a potential therapy for resistant cases. However, there remains considerable uncertainty over the safety and efficacy of this procedure, in particular the incidence of intraprocedural and delayed complications and in the longevity of sinus patency, pressure gradient obliteration, and therapeutic clinical outcome. The aim of this study was to determine clinical, radiological, and manometric outcomes at 3-4 months after DVSS in this treated IIH cohort...

Cerebral infarction (CI) associated with clipping of unruptured intracranial aneurysms (UIAs) has not been completely studied. The role of individual and operative characteristics is not known, and the risk of silent CI has not been well described. To determine the incidence, risk factors, and clinical outcome of postoperative CI, we retrospectively analyzed 388 consecutive patients undergoing clipping of UIAs between January 2012 and December 2015. We reviewed the pre- and postoperative computed tomography (CT) images of each patient...

Intracranial aneurysms (IAs) that undergo rupture causing subarachnoid hemorrhage (SAH), are common in young patients with coarctation of the aorta (CoA), but rarer in middle-aged and elderly patients. The pathogenesis of IAs associated with CoA remains unclear. We report the case of a 50-year-old woman who presented with SAH. On evaluation, six IAs were distributed among the anterior communicating artery (ACoA) (ruptured), distal segments of both anterior cerebral arteries (ACA), the left internal carotid artery (ICA), the bifurcation of the left middle cerebral artery (MCA)/MCA early branch, and the inferior trunk of the left MCA...

INTRODUCTION: Traumatic brain injury (TBI) is a major cause of death and severe prolonged disability. Intracranial hypertension (ICH) is a critical risk factor of bad outcomes after TBI. Continuous infusion of hyperosmolar therapy has been proposed for the prevention and the treatment of ICH. Whether an early administration of continuous hyperosmolar therapy improves long-term outcomes of patients with TBI is uncertain. The aim of the COBI study (number clinicaltrial.gov 03143751, pre-results stage) is to assess the efficiency and the safety of continuous hyperosmolar therapy in patients with TBI...
