American Journal of Roentgenology, 1969
A review is made of 234 cases of choroid plexus papillomas collected from the literature, to which 11 unpublished personal cases are added.The clinical features, plain roentgenographic findings of the skull, and the value of pneumography, cerebral angiography and gamma encephalography in establishing the diagnosis are discussed in detail.The majority ...

Choroid plexus taurine transport
Brain Research, 1996The putative osmoregulatory agent, taurine, is lost from the brain during hypo-osmotic stress or ischemia, but the regulatory mechanisms involved in this loss have not been fully elucidated. In this study, we have examined taurine transport by the isolated rat choroid plexus, one element of the brain-blood interface, and examined how it may be ...

Scientific American, 1989
T he brain is choosy about what it allows to enter its tissues. Because it can function only in a chemically stable environment, the brain shuts out most water-soluble substances in the blood-even some potentially helpful medications. Three structures stand as gatekeepers to the brain's interior: the network of cere bral capillaries, the arachnoid mem

Xanthogranulomas of choroid plexus
Neuroradiology, 1987Computed tomographic features of xanthogranulomas of the choroid plexus are presented. The characteristic location of bilateral intense homogeneously enhanced masses with central lucencies is thought to be diagnostic of xanthogranuloma of the choroid plexus.

Choroid plexus histidine transport
Brain Research, 1998System-N transport plays an important role in l-glutamine uptake into isolated rat choroid plexus but its role in the transport of another System-N substrate, l-histidine, has yet to be determined. Similarly, the possible effects on System-N mediated l-histidine transport of changes in pH and extracellular l-glutamine, such as occur in cerebral ...

Isolated choroid plexus lipomas
Computerized Medical Imaging and Graphics, 1995Seven patients with isolated choroid plexus lipomas were found during the consecutive evaluation of 5351 CT and 1542 MR examinations of the brain during approximately 9 months, from the diagnosis of the first case up to the last one. Five patients were adults and two were children (one neonate).

Aggressive choroid plexus papilloma
Surgical Neurology, 1984A young woman, who was initially treated for an Arnold-Chiari malformation, was found 7 years later to have a posterior third ventricular tumor. A superior cerebellar approach allowed total resection of the mass, which was an aggressive choroid plexus papilloma. The patient was treated with whole cerebrospinal axis radiation.

Pediatric choroid plexus neoplasms
International Journal of Radiation Oncology*Biology*Physics, 1998Choroid plexus tumors (CPT) are rare childhood neoplasms. The relatively small number of reported cases and the controversies surrounding the clinical and pathological classification of these tumors have made it difficult to define a standard of care for these patients. Our intention is to contribute to the body of knowledge of these tumors and further

The isolated choroid plexus cyst
Obstetrics & Gynecology, 1998To describe the karyotypes of a population of fetuses with choroid plexus cysts and compare affected fetuses with and without additional ultrasonographic findings.The study population included all patients undergoing second-trimester ultrasound examination in a prenatal diagnostic program between January 1993 and October 1995.

Choroid plexus papillomas - Neuroradiological diagnosis
min - Minimally Invasive Neurosurgery, 1982The radiographic data on 28 cases of papilloma of the choroid plexuses observed at the Neurosurgical Institute of Rome Medical School in the space of 27 years, are presented and compared with the published series. On the present evidence CT has a high diagnostic value in this disease, although angiography is still generally necessary for a pre ...
