A 30 year-old woman presented with headaches, nausea, vomiting and an unsteady gait. |
| Ependymoma. T2-weighted axial MRI scans.
Note the large midline cerebellar mass invading the roof of the fourth ventricle
and growing downward into the foramen magnum. Surgical resection showed the
mass to be an ependymoma. Ependymomas originate either from the ependymal cells
that line the ventricles or are
located in the central canal of the spinal cord. They are rare brain
and spinal cord tumors, and are more commonly found in children.
When they arise in the
brainstem, they often result in non-communicating hydrocephalus,
focal brainstem signs, or both. |
