| ABSTRACT |
|
Papilloma of the choroids plexus is a rare tumor with an incidence of 0.4% to 3.9% among all intracranial tumors.
This tumor, which is typically located in the lateral ventricles of young children, while most of the tumors in adults were located in the 4 th ventricle, is amenable to surgical removal. We report a case of choroid plexus papilloma of the 4 th ventricle in 17 years old boy with complaints of occipital headache, progressing ataxia and decreased visual acuity. The tumor occupying 4 th ventricle and cisterna magna was a hen's egg sized pinkish globular mass with irregular papillary surface. Microscopically there are monotonous pattern of branching fibrous stroma, containing many blood vessels, radiating from a single area and covered with simple columnar epithelial cells. |
