چکیده

Dr. Lucas Perez de Vasconcellos – Rua Desembargador Joaquim Barbosa de Almeida 368 05463-010 São Paulo SP Brasil. E-mail: lucas.vasconcellos@ terra.com.br Intraventricular tumours represent around 10% of central nervous system tumours. A variety of intraventricular tumours can be found, with the differential diagnosis depending upon the location in the ventricular system. In the lateral ventricles, the more common intraventricular tumours are meningiomas, astrocytomas and ependymomas, whereas choroid plexus papillomas and carcinomas, subependymomas and dermoid cysts are rare. We report a case of intraventricular schwannoma of the choroid plexus in the lateral ventricle, presenting with headache.

Choroid plexus hemorrhage in premature neonates: recognition by sonography.

In 34 consecutive infants admitted to the neonatal intensive care unit with birth weight of less than 1,500 g, 80 cranial real-time sonograms were obtained to determine the incidence of choroid plexus hemorrhage. Choroid plexus hemorrhage was diagnosed only in the absence of germinal matrix hemorrhage. Diagnostic criteria included choroid plexus nodularity, enlargement (greater than 12 mm in an...

Choroid plexus tuberculoma. Diagnosis, management and role of endoscopy.

Ventricular involvement in central nervous system tuberculosis can be in the form of tuberculous ependymitis, intraventricular tuberculoma, intraventricular tuberculous abscess, choroid plexitis and choroid plexus tuberculoma. Only a few cases of choroid plexus tuberculomas have been described and even more rare is the description of the role of endoscopy in management of intraventricular tuber...

Acute unilateral hydrocephalus resulting from oedematous occlusion of foramen of Monro: complication of intraventricular surgery.

Transcerebral removal of a small choroid plexus papilloma in the region of the foramen of Monro was followed within 48 hours by severe and progressive unilateral hydrocephalus. Acute unilateral hydrocephalus is a hitherto unrecognized complication of intraventricular surgery.

The interventricular extension of choroid plexus papillomas.

Four cases of choroid plexus papilloma extending through the foramen of Monro are presented. All four patients were evaluated by contrast-enhanced CT and two of these were also evaluated by neurosonography. No other intraventricular tumor commonly extends through a ventricular outlet. The radiographic demonstration of this extension of an intraventricular mass through the foramen of Monro, cere...

Epithelial pathways in choroid plexus electrolyte transport.

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.
