Tanycytic ependymoma derives its name from its spindly, bipolar tumor cells resembling tanycytes. Tumor cells are arranged in fascicles or variable width and cell density. Ependymal rosettes are absent and pseudorosettes only vaguely delineated. These lesions exhibit a proclivity for the spinal cord, and may be mistaken for astrocytoma.
