Ependymoma in Sellar Region:Report of One Case / 中国医学科学院学报

ABSTRACT

Ependymoma arises from the ependymal cells of the ventricles and the ependymal cell nest in the white matter of the extra-ventricles. It may be located inside or outside ventricle and can be anatomically classified into supra- and infratentorial ependymomas. Supratentorial ependymoma can be found both inside and outside ventricle but is rarely seen in the sellar regio. This article reports a pathologically confirmed ependymoma case featured by plastic growth,nodular calcification,and flow-void signal.
