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 ...

Pediatric Neurosurgery, 1976
Utilizing a ventricular perfusion technique, the rate of CSF formation was determined in a 2-year-old child before and after removal of a 74 g choroid plexus papilloma from the left lateral ventricle. Preoperatively, the CSF formation rate was 1.05 + SD 0.01 ml/min (1,656 ml/day).

Journal of Neurosurgery, 1961
p APILLOMAS of the choroid plexus are relatively rare and, including our present cases, a total of 143 have been reported to June 1960. The incidence at this clinic is 0.4 per cent of verified intracranial tumors. Since most reports in the literature have concerned one or two eases and because papillomas generally are considered to have a high surgical

Papillomas of the Choroid Plexus
Journal of Neurosurgery, 1968p APILLOMAS of the choroid plexus are solitary reddish grey tumors attached to the choroid plexus. The irregular surface is covered by a thin transparent capsule, and the firm tumor occasionally is partly calcified. Microscopically, papillomas resemble normal choroid plexus, being composed of columnar or cuboidal epithelium supported by highly ...

Third Ventricle Choroid Plexus Papillomas
Pediatric Neurosurgery, 1983Choroid plexus papillomas are only infrequently located in the third ventricle. Two infants with such lesions are presented and the diagnosis by computed tomography described. The transcallosal approach to the third ventricle was employed in both cases and led to successful excision.

Choroid plexus papillomas in childhood
Journal of Clinical Neuroscience, 1995Chroid plexus papillomas account for only 0.4-0.6% of intracranial tumours at all ages and less than 5% in childhood. Two paediatric cases are reported to demonstrate the variability in clinical presentation, location and neurological outcome of this benign tumour. One case has been followed for 13 years.

Medullary cistern choroid plexus papilloma
Child's Nervous System, 2010Objective and importance Choroid plexus papillomas (CPP) are benign neoplasms of ventricular ependymal origin that make up 0.5–0.6% of all adult brain tumors but are more commonly seen in the pediatric population [8]. Gross total resection is the surgical objective, and when achieved, 10-year survival can approach 75% [20].

1986
The ultrastructural appearances of choroid plexus papillomas are very similar to those of normal choroid plexus tissue, and the many specialised features suggest that the neoplastic cells may have retained the ability to produce cerebrospinal fluid. The cells are mainly columnar in shape and are usually arranged in a papillary pattern with distinct ...

Choroid plexus papilloma containing bone
Acta Neuropathologica, 1985The presence of bone in choroid plexus papillomas is a rare event. The authors report a case of choroid plexus papilloma of the IVth ventricle containing bone in a 18-year-old man, and review two previously reported cases, as well as the mechanisms proposed for the presence of bone and cartilage in neuroepithelial neoplasms.
