Comparative StudyTwenty colloid cysts--comparison of endoscopic and microsurgical management.
The management of colloid cyst remains controversial, evaluation of the competing methods seems to be necessary. We report on our experience with colloid cysts in the last decade: ten were managed solely endoscopically, 10 were resected microsurgically (9 via a transcortical/transventricular, 1 via a transcallosal approach). The outcome in the endoscopic group was excellent in 9 cases and unsatisfying in 1 case (recurrence). ⋯ Endoscopic management results in lower costs and superior patients' comfort. The reduced number of total resections in the endoscopic group may lead to a higher recurrence rate in long-term follow-up, which might be a serious disadvantage of endoscopy. However, more experience in the endoscopic techniques may result in a higher rate of total resection of colloid cysts.

Case ReportsNeuroendoscopic treatment of cystic craniopharyngioma in the third ventricle.
The third ventricle is a relatively uncommon location for craniopharyngiomas. Generally, craniotomy has been considered the procedure of choice in such cases. We describe a girl in whom a cystic third ventricular craniopharyngioma was successfully treated by evacuation of the cyst contents via a flexible neuroendoscope and precise placement of an Ommaya reservoir catheter within the tumor.

Electronic database for documentation of microsurgical and endovascular treatment of intracranial aneurysms: technical note.
The authors present an electronic database for the documentation and inter-group comparison of patients subjected to microsurgical and/or endovascular therapy of ruptured and unruptured intracranial aneurysms.

Case ReportsTransient hyponatriemia complicated by seizures after endoscopic third ventriculostomy.
We present an infant who underwent endoscopic third ventriculostomy due to symptomatic hydrocephalus secondary to aqueductal stenosis. This is the first reported case of inappropriate secretion of antidiuretic hormone complicated by hyponatriemia and seizures following endoscopic surgery. The possibility of such a neuroendoscopic complication should alert neurosurgeons and close observation of serum electrolytes is highly recommended in the acute postoperative period, particularly in infants.

Endoscopic treatment of para- and intraventricular cerebrospinal fluid cysts.
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. ⋯ 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.
