title: Myxochondrosarcoma of the fourth ventricle. Case report.
abstract: The authors report a case of myxochondrosarcoma of the fourth ventricle. The tumor was heavily calcified and proved impossible to remove at surgery. Histological examination revealed areas of loose fibroblastic tissue, hyaline cartilage, osteoid, and bone. It is postulated that the tumor arose from the stroma of the choroid plexus.
