Magnetic Resonance Imaging of Fourth Ventricular Choroid Plexus Neoplasms in Childhood
Pediatric Neurosurgery, 2008Choroid plexus neoplasms (CPN) are rare tumors occurring with a relative incidence of 0.5% of intracranial neoplasms in all age groups and 1.5–6.4% of all pediatric brain tumors. In children, the most common site of origin is the atria of the lateral ventricles where the CPN may represent either a carcinoma or a benign papilloma.

Pathology, 2014
Choroid plexus papillomas are uncommon, benign (WHO grade 1) tumours which most frequently arise in the lateral or fourth ventricle of young adults and children. Oncocytic change is rare in the central nervous system and its tumours, and only a few cases of the oncocytic variant of choroid plexus papilloma have been reported.

Histopathology, 1996
MIB-1 immunohistochemistry was carried out on a retrospective biopsy series of epithelial choroid plexus neoplasms in order to assess the proliferation rate of tumour cells. The material included 14 cases of papilloma (WHO grade I) and five cases of carcinoma (WHO grade III).

A marker for primary choroid plexus neoplasms.
The American journal of pathology, 1990Primary 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 ...

Transthyretin immunoreactivity in choroid plexus neoplasms and brain metastases.
Modern pathology : an official journal of the United States and Canadian Academy of Pathology, Inc, 1992Although choroid plexus papillomas (CPP) and primary choroid plexus carcinomas (CPC) are rare neoplasms of the central nervous system, they have been the subject of a number of immunohistochemical studies. To date, no unique or specific marker for these neoplasms has been found, however.

Veterinary Pathology
A 6-year-old, castrated male, domestic shorthair cat with progressive neurologic signs underwent magnetic resonance imaging, revealing a suprasellar mass, which resulted in euthanasia. Grossly, a tan-red tumor expanded the ventral third ventricle, compressed adjacent brain structures, and emerged ventrally at the midline.
