Virchow-Robin spaces (VRS) are extensions of the subarachnoid space surrounding perforating blood vessels entering the brain parenchyma. VRS are fluid filled, but almost virtual and only visible on MRI of the brain when dilated. Such dilations are commonly asymptomatic. In rare cases, extreme dilations can be observed; the clinical repercussions of which remain unclear. We report the case of a patient presenting symptoms of normal pressure hydrocephalus due to extreme VRS mesencephalon dilations.

The effect of temporary CSF diversion modality on shunt-dependency following aneurysmal subarachnoid hemorrhage: A nationwide assessment.
J Clin Neurosci

Department of Neurological Surgery, Keck School of Medicine of the University of Southern California, Los Angeles, CA, USA.
Background: Aneurysmal subarachnoid hemorrhage (aSAH) carries a high economic cost and clinical morbidity in the United States. Beyond prolonged admissions and poor post-injury functional status, there is an additional cost of chronic shunt-dependent hydrocephalus for many aSAH patients. Adjuvant lumbar drain (LD) placement has been hypothesized to promote clearance of subarachnoid blood from the cisternal space, with an ultimate effect of decreasing shunt placement rates.

Objective: Tumors in the ventral craniocervical junction (CCJ) pose unique challenges, particularly in children. The potential constraints with endoscopic approaches to tumors extending inferiorly and laterally and the risk of CSF leakage can be exacerbated in the pediatric population. Here, the authors present their experience with the extreme lateral transodontoid (ELTO) approach in children with large ventral CCJ tumors as an alternative or complement to anterior approaches.

Objective: The Endoscopic Third Ventriculostomy Success Score (ETVSS) is a useful decision-making heuristic when considering the probability of surgical success, defined traditionally as no repeat cerebrospinal fluid diversion surgery needed within 6 months. Nonetheless, the performance of the logistic regression (LR) model in the original 2009 study was modest, with an area under the receiver operating characteristic curve (AUROC) of 0.68.
