Background:
Obstruction of the foramina of Magendie and Luschka represents one possible aetiology for a progressive tetra-ventricular hydrocephalus.
Method:
Our case report is a 58-year-old woman initially presenting with a pseudo-vertebrobasilar insufficiency clinical syndrome. A ventriculo-cisternostomy of the third ventricle was performed by an endoscopic procedure with a clinical and radiological success (three year follow-up).
Findings:
Comparative studies of cerebrospinal fluid (CSF) flow measurements by cine magnetic resonance imaging (cine-MRI) showed that Magendie's and Luschka's foramina permeabilities were restored after the ventriculo-cisternostomy. INRTERPRETATION: This case shows that endoscopic ventriculo-cisternostomy of the third ventricle can provide an effective treatment for specific tetra-ventricular hydrocephalus. Cine-MRI findings open the discussion on possible aetiologies and pathophysiologies.

Local Anesthetics: Mechanism of Action
Local anesthetics are amphiphilic molecules consisting of a hydrophobic aromatic part linked to a hydrophilic group by an ester or amide linkage. They are weak bases and are usually available as salts, which increases their solubility and stability. Once administered, LAs exist in the body either...
