BACKGROUND: This paper describes a case of 4th ventricular mass, whose management had to be modified due to a rare variation of the occipital sinus (OS). CLINICAL DESCRIPTION: 32 year-old female presented with persistent headache and nausea. MRI showed a 4th ventricular mass and hydrocephalus. Venous sinus anatomy appeared unusual, thus an MRV was performed. MRV revealed the OS as the main drainage pathway for the whole brain, providing the only drainage between the superior sagittal sinus and the jugular veins through the marginal sinus (MS)...

Iatrogenic ventriculitis is a potential complication of ventriculostomy drain placement. In this study, an alcohol-impregnated external ventricular drain port cap was added to a standardized ventriculostomy placement bundle. Rates of ventriculitis were reduced postintervention, but this finding did not reach statistical significance.

OBJECTIVE: intraventricular hemorrhage (IVH) often requires the insertion of an external ventricular drain (EVD), but blood clots could occlude the catheters. Large EVD catheters may help to reduce the risk of catheter occlusion. Here, we compared small catheters with large catheters for ventriculostomy in patients suffering from IVH. METHODS: We conducted a retrospective cohort study. Patients were included if they had IVH requiring EVD insertion. We then compared baseline characteristics and outcomes of patients treated with large catheters to patients treated with small catheters...

Hydrocephalus is one of the commonest complications of tuberculous meningitis (TBM). It can be purely obstructive, purely communicating, or due to combinations of obstruction in addition to defective absorption of cerebrospinal fluid (CSF). Endoscopic third ventriculostomy (ETV) as an alternative to shunt procedures is an established treatment for obstructive hydrocephalus in TBM. ETV in TBM hydrocephalus can be technically very difficult, especially in acute stage of disease due to inflamed, thick, and opaque third ventricle floor...

OBJECTIVES: The management of neonatal post-haemorrhagic hydrocephalus (nPHH) varies considerably between centres and even between neurosurgeons in the same centre. We performed a nationwide survey to evaluate current practice in the UK and reviewed the evidence for each intervention. METHODS: An online semi-structured questionnaire was emailed to all units registered on the British Paediatric Neurosurgery Group Mailing List. The survey consisted of 18 questions designed to establish the status quo in the management of nPHH, including preferred temporising procedure, factors guiding the timing of intervention and willingness to participate in a prospective study...

BACKGROUND: Conventionally, patients suffering a massive intraventricular hemorrhage have undergone external ventricular drainage. However, long-term or repeated drainage increases the risk of complications due to infections or shunt dependency. Neuroendoscopic surgery may offer some advantages over more conventional procedures. METHODS: Thirteen patients suffering intraventricular hematoma associated with intracerebral hemorrhage, treated in our hospital between April 2011 and March 2014, were reviewed retrospectively...

A 69-year-old woman presented with anorexia, fever, and vomiting. The patient was not a compromised host. She was finally diagnosed with <i>Listeria</i> meningitis and treated with ampicillin and gentamicin. However, her condition worsened over time. Non-contrast head CT showed ventricular dilatation. As a result, continuous right ventricular drainage was performed. Non-contrast MRI revealed hydrocephalus due to stenosis of the fourth ventricle. She underwent endoscopic third ventriculostomy(ETV)to improve cerebrospinal fluid circulation...

OBJECTIVE The efficacy of endoscopic third ventriculostomy (ETV) for the treatment of pediatric hydrocephalus has been extensively reported in the literature. However, ETV-related long-term outcome data are lacking for the adult hydrocephalus population. The objective of the present study was to assess the role of ETV as a primary or secondary treatment for hydrocephalus in adults. METHODS The authors performed a retrospective chart review of all adult patients (age ≥ 18 years) with symptomatic hydrocephalus treated with ETV in Calgary, Canada, over a span of 20 years (1994-2014)...

OBJECTIVE Endoscopic third ventriculostomy with choroid plexus cauterization (ETV/CPC) offers an alternative to shunt treatment for infantile hydrocephalus. Diagnosing treatment failure is dependent on infantile hydrocephalus metrics, including head circumference, fontanel quality, and ventricle size. However, it is not clear to what degree these metrics should be expected to change after ETV/CPC. Using these clinical metrics, the authors present and analyze the decision making in cases of ETV/CPC failure. METHODS Infantile hydrocephalus metrics, including bulging fontanel, head circumference z-score, and frontal and occipital horn ratio (FOHR), were compared between ETV/CPC failures and successes...

BACKGROUND: Many studies have shown that cerebrospinal fluid (CSF) behaves irregularly, rather than with laminar flow, in the various CSF spaces. We adapted a modified previous known magnetic resonance imaging technique to visualize irregular CSF motion. Subsequently, we assessed the usefulness and clinical significance of the present method. MATERIALS AND METHODS: Normal CSF motion in 10 healthy volunteers was visualized with the dynamic improved motion-sensitized driven-equilibrium steady-state free precession technique...
