Histopathology

MICROSCOPIC DESCRIPTION: Paraffin sections show fragments of a moderately hypercellular ependymoma. Tumor cells show mild nuclear pleomorphism. A very occasional mitotic figure is identified (1 in 20 HPF). There is no microvascular proliferation and no necrosis is identified. Part of the lining of an ependymal canal is noted at one edge of one fragment.

DIAGNOSIS: Cervical spinal tumor: Ependymoma (WHO Grade II).
