Spinal arachnoiditis (SA) is an extremely rare and delayed complication of subarachnoid hemorrhage (SAH). Little is known about its underlying pathogenesis and subsequent clinical course. A middle-aged patient presented with the worst headache of her life and a grade 3 SAH of the basal-cisterns and posterior fossa was identified on Computed Tomography scans (CT). Angiography revealed a ruptured dissecting aneurysm of the left vertebral artery (VA-V4), as well as an unruptured left Anterior Cerebral Artery (ACA-A1) aneurysm...

Central nervous system infection by Toxoplasma gondii, or Toxoplasma encephalitis, is the most common cause of brain mass lesions in human immunodeficiency virus (HIV)-infected patients. It usually presents as one or more brain abscesses, but it can also cause a diffuse encephalitis or ventriculitis. Individuals who are Toxoplasma immunoglobulin G-seropositive, who have peripheral blood CD4+ T-cell concentrations below 200/μL, are not on antiretroviral therapy, and are not taking trimethoprim-sulfamethoxazole to prevent Pneumocystis pneumonia, are at particular risk for Toxoplasma encephalitis...

Traumatic brain injury (TBI) is in part associated with the disruption of the blood-brain barrier. In this study, we analyzed the histopathological changes in E-cadherin and VEGF expression after traumatic brain injury in rats. The rats were divided into 2 groups as the control and the trauma groups. Sprague-Dawley rats were subjected to traumatic brain injury with a weight-drop device using 300 g⁻¹ m weight-height impact. After 5 days of traumatic brain injury, blood samples were taken under ketamine hydroxide anesthesia and biochemical analyzes were performed...

Prenatal, neonatal meningoencephalitis and infections of the brain in older infants are often associated with serious complications which can be diagnosed by sonography through the open fontanelles. Most frequently postmeningitic hydrocephalus and subdural effusions occur. Rarer complications are brain abscesses and ventriculitis which are caused by gram negative bacteria such as E. coli, Serratia marcescens, Proteus and Enterobacter. A serious complication after ventriculitis is the development of compartment hydrocephalus...

REVIEW
Katharina Maria Busl
Infectious complications in the neurointensive care unit (neuro-ICU) are common, including pneumonia, urinary tract infection, bloodstream infection, and intracranial infection. The neuro-ICU population poses a specific challenge in the diagnosis of infections, because of the high incidence of fever in acutely brain-injured patients. Furthermore, susceptibility to infections is likely enhanced by brain-injury (induced immune modulation). This article reviews the concept of brain injury-induced immune modulation, and summarizes available data and knowledge on nosocomial meningitis and ventriculitis, and systemic infectious complications in patients with traumatic brain injury, ischemic stroke, intracerebral hemorrhage, subarachnoid hemorrhage, and status epilepticus...

BACKGROUND: External ventricular drain (EVD)-associated ventriculitis is a serious complication. Early diagnosis can be difficult particularly in critically ill patients with aneurysmal subarachnoid hemorrhage (aSAH). We examined the diagnostic potential of standard serum and cerebrospinal fluid (CSF) biomarkers to differentiate between EVD-associated infections and aseptic courses in patients with aSAH. MATERIALS AND METHODS: We retrospectively evaluated the levels of inflammatory markers in serum (white blood cell count, percentage of neutrophils [sN%], and procalcitonin) and CSF (total leukocyte count [CSFTLC], CSFglucose, CSF/serumglucose ratio, CSF total protein [CSFTP]) of 63 consecutive patients with aSAH...

Background: Acinetobacter baumannii nosocomial ventriculitis/meningitis, especially those due to drug-resistant strains, has substantially increased over recent years. However, limited therapeutic options exist for the Acinetobacter baumannii ventriculitis/meningitis because of the poor penetration rate of most antibiotics through the blood-brain barrier. Case presentation: A 57-year-old male patient developed ventriculitis from an extensively drug-resistant strain of Acinetobacter baumannii after the decompressive craniectomy for severe traumatic brain injury...

Streptococcus suis, a gram-positive facultative anaerobe commonly found in pigs, is an emerging zoonotic pathogen. Herein, we describe a case of a 45-year-old male Japanese meat wholesaler with S. suis meningitis and pyogenic ventriculitis. S. suis was isolated from his blood and cerebrospinal fluid culture, and sequence type (ST) and serotype were confirmed to be ST1 and serotype 2, respectively, by multilocus sequence typing and the Quellung reaction. Magnetic resonance imaging (MRI) revealed right labyrinthitis and pyogenic ventriculitis...

OBJECTIVE: Acutely ruptured aneurysms can be treated by endovascular intervention or via surgery (clipping). After endovascular treatment, the risk of thromboembolic complications is reduced by the use of anticoagulative agents, which is not required after clipping. The aim of the study is to investigate the rate of ventriculostomy-related hemorrhage after endovascular treatment and clipping. METHODS: A consecutive series of 99 patients treated for a ruptured aneurysm which required an external ventricular drainage between 2010 and 2015 were included...

Bacterial infections of the central nervous system (CNS) continue to be an important cause of morbidity and mortality in children. The spectrum of bacterial infection of CNS includes; focal or multifocal infections like brain abscesses or subdural empyema; or more generalized or diffuse infections like pyogenic meningitis or ventriculitis. Focal and generalized infections may co-exist in an individual patient. Prompt and adequate antibiotic therapy and occasionally neurosurgical interventions are the cornerstone of effective management...

We present a case report of a 58-year- old woman with subarachnoid haemorrhage complicated by non-communicating hydrocephalus. During the course of her neurosurgical management, she developed external-ventricular drain associated ventriculitis which in turn was complicated by lack of communication between third and fourth ventricles. The causative organism was a fully-sensitive Acinetobacter baumanii , a nosocomial pathogen often associated with complicated treatment regimens and poor outcomes. This patient was successfully managed by a multi-disciplinary team involving neurosurgeons, neuroradiologists and infection specialists...
