This study has been made to define the role of endoscopy and the most appropriate
approach and technique of endoscopic fenestration of paraventricular and intraventricular
CSF cysts according to the cyst size and location. Twenty-two patients with intraventricular
(13 cases) and paraventricular (9 cases) CSF cysts, operated upon by endoscopic technique
in three Italian neurosurgical centers, are reviewed. Paraventricular hemispheric
cysts have been treated by endoscopic fenestration from the cyst to the lateral ventricle.
Midline intraventricular cysts (2 of the septum pellucidum and 4 of the velum interpositum)
underwent fenestration from the right lateral ventricle to the cyst, with fenestration
in both lateral ventricles in one case. Cysts of the choroid plexus have been fenestrated
from the homolateral enlarged ventricle (4 cases) or from the contralateral compressed
ventricle (2 cases). Twenty patients (more than 90 %) were definitively cured by the
endoscopic procedure, whereas only 2 patients required a shunt or a direct approach.
We think that the endoscopic fenestration must be considered the treatment of choice
of intraventricular and paraventricular CSF cysts.
