A 30 year-old woman presented with headaches, nausea, vomiting and an unsteady gait. |
| Ependymoma. (Left) T1-weighted
with gadolinium coronal MRI; (Right) T1-weighted with gadolinium
sagittal MRI.
Note the large midline enhancing 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. |
