title: Colloid cyst of the third ventricle with XYY-syndrome.
abstract: Case presentation of an intra-uterine diagnosed third ventricle colloid cyst in a male with XYY-Syndrom. The inner cellular cover of cyst was composed by flat or cuboidal to columnar epithelium, which beared cilia in some areas. Other cells of the inner cover showed protrusions of cytoplasm, which extended into the cyst cavity. The cyst wall showed loosely arranged fibrous connective tissue, some Plasmocytes, and a few cells with granulated plasma. The histogenesis of this cyst was suggested immunohistologically from primitive neuroepithelial structures. According to sonographic findings an intra-uterine diagnosed intracerebral cyst should be a cause to search other malformations.
