Clinical Study


A brain tumor in the fourth ventricle of a 26-year-old woman displayed numerous Homer Wright rosettes by conventional histology, but immunostaining and electron microscopy revealed the tumor an ependymoma. Since the presence of Homer Wright rosettes in ependymoma has not been well appreciated in the past, the diagnostic importance of this finding is discussed.
