Intraventricular myxopapillary ependymoma
The location of the myxopapillary ependymoma was intraventricular in two cases, where ependymal cells are normally present.
Warnick et al, report a 37-year-old woman who developed recurrent symptoms, including scotomas, disorientation, and headache, during two successive pregnancies before the definitive diagnosis 1).
