Supratentorial tanycytic ependymoma: an uncommon fibrillary ependymoma variant.

A 6-year-old boy with focal seizures and headache. Diagnostic imaging demonstrated a right subcortical parietooccipital heterogeous expansive lesion, with growth into the adjacent ventricular system (Fig 1). Histological analysis led to the diagnosis of tanycytic ependymoma, as tumor cells have features resembling tanycytes (Fig 2). More than half of these tumors occur in the spinal cord. Supratentorial location is very rare, and may arise, as in this case, around the ventricle or from subcortical white matter. ACKNOWLEDGEMENT – Anatomical specimen kindly referred by
