Non-Enhancing Intradural Extramedullary Ependymoma: A Case Report

|October 14, 2022
Summary
This study reports a rare intradural extramedullary spinal ependymoma in an adult female. The tumor showed no contrast enhancement on MRI, which is unusual for spinal ependymomas.
Area of Science:
- Neuro-oncology
- Spinal cord imaging
- Neurosurgery
Background:
- Spinal ependymomas typically occur within the intramedullary compartment in adults.
- Intradural extramedullary ependymomas are exceptionally rare spinal tumors.
- Spinal ependymomas exhibit diverse contrast enhancement patterns on Magnetic Resonance Imaging (MRI).
Observation:
- A 52-year-old female presented with a spinal tumor.
- The tumor was pathologically confirmed as an intradural extramedullary ependymoma.
- MRI revealed no contrast enhancement of the ependymoma.
Findings:
- This case highlights an extremely rare instance of an intradural extramedullary spinal ependymoma.
- The ependymoma demonstrated an atypical lack of contrast enhancement on MRI.
- This finding contrasts with the typical variable enhancement seen in spinal ependymomas.
Implications:
- The study expands the understanding of imaging characteristics for rare spinal tumors.
- It suggests that the absence of MRI enhancement does not exclude ependymoma diagnosis.
- This case emphasizes the importance of integrating imaging findings with pathological confirmation in diagnosing spinal ependymomas.
