Histology

MICROSCOPIC DESCRIPTION: The sections show a moderately hypercellular tumour. This consists of ependymal cells arranged in well formed perivascular pseudo-rosettes. Myxoid material is present within the pseudo-rosettes. Tumour cells are arranged in diffuse sheets between pseudo-rosettes.  No mitotic figures are identified and there is no vascular  endothelial cell hyperplasia and no necrosis. The features are of myxopapillary ependymoma.

DIAGNOSIS: Myxopapillary ependymoma  (WHO Grade I)
