The American Journal of Surgical Pathology, 1986 Choroid plexus neoplasms account for less than 1% of all intracranial tumors, with papillomas (CPPs) more frequent than carcinomas (CPCs). Immunocytochemical characterization of these neoplasms has been limited. Glial fibrillary acidic protein (GFAP), S100 protein, and keratin have been variably demonstrated by others.

, 2016 Intraventricular neoplasms derived from choroid plexus epithelium including choroid plexus papilloma (WHO grade I), atypical choroid plexus papilloma (WHO grade II), and choroid plexus carcinoma (WHO grade III). The vast majority are sporadic, though rarely arise in association with hereditary cancer predisposition syndromes, including the Li Fraumeni ...

THE NEURORADIOLOGY OF CHILDHOOD CHOROID PLEXUS NEOPLASMS
American Journal of Roentgenology, 1973 The features of 14 cases of choroid plexus neoplasms from the Hospital for Sick Children, Toronto, are presented, and similar available data from 130 previously reported cases in children are tabulated.In any neuroradiologic practice, choroid plexus papillomas and carcinomas are rarely encountered.

NEOPLASM OF THE CHOROID PLEXUS
American Journal of Diseases of Children, 1934 Neoplasms of the brain in infancy undoubtedly occur with greater frequency than reports of their discovery would suggest. Because of the readiness with which their symptomatology may be confused with that of gastro-intestinal dysfunction, particularly projectile vomiting, uncomplicated by a lesion of the nervous system, recognition of the presence of ...

Pediatric choroid plexus neoplasms: MR, CT, and pathologic correlation.
Radiology, 1989 Choroid plexus papillomas are rare, constituting approximately 0.5% of all intracranial neoplasms. Four benign choroid plexus papillomas and one choroid plexus carcinoma were retrospectively reviewed in patients aged 4-20 months who had been examined with magnetic resonance (MR) imaging with a field strength of 0.5 T or 1.0 T and with computed ...

Ultrasonic diagnosis of a choroid plexus neoplasm in a child
The British Journal of Radiology, 1984 Choroid plexus neoplasms arise from the epithelial cells of the choroid plexus of the brain and can occur wherever choroid plexus is found within the cranial cavity. Although relatively uncommon, these tumours are usually benign and are often accessible to surgical removal. It is therefore of paramount importance that their presence be recognised early

The Role of Radiotherapy in the Management of Choroid Plexus Neoplasms
Tumori Journal, 1989 Choroid plexus papillomas are very rarely reported neoplasms in both the surgical and radiological literature. The authors present their series of 7 papillomas and 1 carcinoma. They review the recent and former literature with the aim of demonstrating the role and usefulness of radiotherapy.

A marker for primary choroid plexus neoplasms.
The American journal of pathology, 1990 Primary choroid plexus (CP) tumors are rare neoplasms that present in childhood or, less frequently, in adult life. The majority are benign and amenable to complete surgical excision, but occasionally more invasive variants are encountered. Although generally pathologically distinct, occasionally primary CP neoplasms may be difficult to distinguish ...

Childhood choroid plexus neoplasms
European Journal of Pediatrics, 1983 Fourteen children less than 2 years old with choroid plexus papilloma (CPP) were studied. Of these patients nine had the tumor in the lateral ventricles (LV), three in the fourth ventricle (4th V), one in the third ventricle (3rd V) and one in the third and left lateral ventricle (LLV).

Clinicopathologic correlations in epithelial choroid plexus neoplasms: a study of 52 cases
Acta Neuropathologica, 1990 Sixty-seven tumor specimens of epithelial choroid plexus neoplasms obtained by 60 biopsies and 7 autopsies from 52 patients were investigated. Diagnoses of the first operations were choroid plexus papilloma (PP; 32 cases), choroid plexus papilloma with histological atypies (atypical PP; 6 cases), and choroid plexus carcinoma (PC; 14 cases ...
