A stable intraventricular milieu is crucial for maintaining normal neuronal function. The choroid plexus epithelium produces the cerebrospinal fluid and in doing so influences the chemical composition of the interstitial fluid of the brain. Here, we review the molecular pathways involved in transport of the electrolytes Na+, K+, Cl-, and HCO3(-)across the choroid plexus epithelium.

Choroid plexus papilloma (CPP) is a rare benign tumor of the central nervous system with a propensity for location within the lateral ventricle in children. We report a case of a 14-year-old girl who presented with transient facial paresis and ataxia. Her imaging showed a non-enhancing intra fourth ventricular mass, the histology of which was reported as CPP. The atypical clinical and radiologi...

Choroid plexus papillomas are rare intracranial neoplasms that are most commonly found in the trigone of the lateral ventricles or in the fourth ventricle. Rare cases of extraventricular choroid plexus papillomas have been reported within the cerebellopontine (CP) angle cistern [1-6]. Such cases have been described as either extending from the fourth ventricle via the foramen of Luschka or aris...

Greenwich and Jahr-Schaffrath (1995) introduced an index Cpp, a simple transformation of the index C∗ pm, which provides an uncontaminated separation between information concerning the process accuracy and process precision. Unfortunately, the index Cpp inconsistently measures process capability in many cases and thus reflects process potential and performance inaccurately. In this paper, we co...

The patient was a 45-year-old man with a progressive headache. Evaluation in detail revealed it as a case of left lateral ventricular space occupying lesion (SOL) resembling choroid plexus papilloma. A left parietal craniotomy was done and the lesion was removed completely through intraparietal approach. Surgical removal resulted in complete symptomatic relief. Histopathology revealed that it w...
