Presentation
Persistent upper back pain following a fall. Reports upper extremity paresthesias.
Patient Data
There is an enhancing, well-circumscribed, expansile mass with mixed solid and fluid components within the central portion of the spinal cord from the inferior endplate of C6 to T1. On T2-weighted images, there is a hypointense rim seen at the periphery of the lesion. There is T2/STIR hyperintensity at the cranial aspect of the lesion which extends to C5.
Case Discussion
This is a spinal ependymoma. The patient underwent C6-T2 laminectomy and resection of the lesion. Histopathologic examination showed evidence of a WHO grade 2 ependymoma without evidence of anaplasia. On immunohistochemistry stains for Ki-67 and PHH3 (B1), there was no significant proliferative activity (Ki-67: <2% and no appreciable mitosis on PHH3).
