This study reports the anatomopathological classification of Tarlov cysts and the various treatment techniques described in the literature. ⋯ The clipping technique for Tarlov cysts is easy, valid, safe, rapid, and effective.

To describe the neuroendoscopic technique to deal with intraventricular tumors. ⋯ Intraventricular tumors and related CSF pathway obstructions can be safely and effectively treated with endoscopic techniques. Small tumors may be totally removed via a ventriculoscope.

The purpose of this review is to describe the magnetic resonance imaging (MRI) findings in patients with noncommunicating hydrocephalus (NCH). ⋯ The first step of the diagnostic work-up consists of the detection of an obstacle hindering CSF flow pathways using both constructive interference in steady state and flow-sensitive MR sequences. CSF volumetry and quantification of ventricular wall movement may also improve the diagnosis and follow-up of patients with NCH.

Endoscopic third ventriculostomy (ETV) is increasingly prevalent among pediatric neurosurgeons as the initial treatment for hydrocephalus. The combination of ETV and choroid plexus cauterization (ETV/CPC) has improved the success rate among infants with hydrocephalus for whom ETV alone is much less successful. In parts of the developing world where there are economic and human resource constraints, this mode of treatment may be more appropriate than the routine use of shunts, which are prone to failures that require urgent surgical treatment. Here we review indications for the use of ETV or ETV/CPC as the primary treatment for hydrocephalus. ⋯ Primary treatment of hydrocephalus by ETV can avoid shunt-dependence and its complications for many patients. Optimal results depend upon proper patient selection and the use of combined ETV/CPC when treating infants.

Entrapped temporal horn syndrome secondary to obstructive neoplastic lesions is most frequently treated by surgical excision of the offending lesion. Here we describe an alternate approach involving temporal horn to prepontine cistern shunting followed by radiosurgery of the offending lesion. ⋯ Trapped temporal horn syndrome secondary to obstructive neoplastic lesions can be treated by internal shunting followed by radiosurgery.
