BACKGROUND: The use of image guidance (IG) in neurosurgery is ubiquitous, even though evidence from patient outcome data has remained limited to smaller, mostly observational, studies. Ommaya reservoir insertion (ORI) has been available as a treatment option for targeted intraventricular pharmacotherapy since the 1960's, far preceding the modern neuronavigation era. We conducted a systematic review and meta-analysis investigating the impact of IG on surgical outcome from ORI. METHODS: A systematic database search of MEDLINE and EMBASE was performed to identify studies on operative outcomes from ORI...

OBJECTIVE: Placement of intraventricular catheters in oncology patients is associated with high complication rates. Placing Ommaya reservoirs with the Zero-Error Precision Protocol (ZEPP), a combination of neuronavigation (AxiEM stealth frameless neuronavigation system) and direct verification of catheter tip placement with a flexible neuroendoscope is associated with decreased complication rates as a result of increased catheter placement accuracy. However, ZEPP costs more than traditional methods of catheter placement and the question of whether this increased accuracy with ZEPP is cost-effective is unknown METHODS: We performed a single-center retrospective chart review of 50 consecutive Ommaya reservoir patient placements between 2010 and 2017...

Cystic brain necrosis (CBN) is a rare form of BN. It typically occurs as a very late complication, and no standard treatment has been established. We report a case of a 59-year-old man who developed CBN 10 years after radiation therapy for metastatic brain tumors. The therapy consisted of whole brain radiotherapy followed by linac-based stereotactic radiosurgery as a boost. Initially, the CBN continued to expand despite treatment with corticosteroids and bevacizumab. Therefore, we resected the tumor and implanted an Ommaya reservoir, which successfully stabilized the lesion...

Meningitis is a common and life-threatening infection of the central nervous system (CNS) in infants with long-term and disabling sequelae like hydrocephalus. Hydrocephalus is treated by diverting cerebrospinal fluid (CSF) either to another body cavity (via CSF shunt) or externally (via CSF drain) which are prone to infection. Though rare, Candida parapsilosis ( C. parapsilosis ) is a known pathogen in device-associated CNS infections and has been reported in both, infants and adults. A six-month-old male infant was brought to the hospital with disproportionate head enlargement of three months duration...

KEY POINTS: During long-term missions, some astronauts experience structural and functional changes of the eyes and brain which resemble signs/symptoms experienced by patients with intracranial hypertension. Weightlessness prevents the normal cerebral volume and pressure 'unloading' associated with upright postures on Earth, which may be part of the cerebral and ocular pathophysiology. By placing the lower body in a negative pressure device (LBNP) that pulls fluid away from cranial compartments, we simulated effects of gravity and significantly lowered pressure within the brain parenchyma and ventricle compartments...

Herein, we describe a fatal case of central nervous system (CNS) pseudallescheriasis following near-drowning. A 13-year-old boy, who had been successfully resuscitated after near-drowning, presented with a transient episode of mental confusion during a hospital stay after recovering from severe aspiration pneumonia and respiratory failure. A magnetic resonance imaging (MRI) scan of the brain showed a small brain abscess in the left basal ganglia and ventriculitis in the left lateral ventricle. The brain abscess and ventriculitis did not respond to 4 weeks of antibiotic treatment and appeared even worse on a follow-up MRI...

OBJECTIVE Diffuse intrinsic pontine glioma (DIPG) is a highly aggressive and lethal brainstem tumor in children. In the 1980s, routine biopsy at presentation was abandoned since it was claimed "unnecessary" for diagnosis. In the last decade, however, several groups have reincorporated this procedure as standard of care or in the context of clinical trials. Expert neurosurgical teams report no mortality and acceptable morbidity, and no relevant complications have been previously described. The aim of this study was to review needle tract dissemination as a potential complication in DIPG...

BACKGROUND: PPAR-δ is a transcription factor which has crucial roles in stimulating oligodendroglial differentiation and myelination and its activation was also shown to differentiate malignant C6 glioma cells into oligodendrocytes. OBJECTIVE: One of the ligands of PPAR-δ is erucic acid (EA), an edible omega-9 fatty acid consumed more by Asian populations and exists highly in Chinese womens milk. There exist epidemiological evidence that pediatric brain tumor incidence is among the lowest in the Chinese population...

REVIEW
Ruairi Wilson, Caroline Osborne, Christina Halsey
Prophylactic eradication of central nervous system (CNS) leukaemia is the current standard of care in treating childhood acute lymphoblastic leukaemia (ALL). This is conventionally achieved through regular lumbar punctures with intrathecal injections of methotrexate into the cerebrospinal fluid (CSF). Ommaya reservoirs are subcutaneous implantable devices that provide a secure route of drug delivery into the CSF via an intraventricular catheter. They are an important alternative in cases where intrathecal injection via lumbar puncture is difficult...

We report a 69-year-old patient with left paresthesia and hemiparesis. Magnetic resonance imaging revealed a right frontoparietal cystic tumor. A subtotal surgical resection was performed, and an Ommaya reservoir was left in place. The pathological diagnosis was supratentorial extraventricular anaplastic ependymoma. Radiation therapy was administered, and Ommaya reservoir drainages were performed. Four months after, her clinical status deteriorated after a reservoir drainage and image revealed an acute hemorrhage...
