Focal classic intradural extramedullary ependymoma near the conus medullaris: A case report and literature review
Xingui Kang, Tao Hu, Keqiang Shi, Quanze Hu, Bin Yu, Ziqi Zhu, Desheng Wu, Yufeng HuangRationale:
To enhance clinicians’ comprehension of conus medullaris region ependymomas and elevate their diagnostic accuracy.
Patient concerns:
A 26-year-old female patient had 10 months of low back pain and right lower limb pain.
Diagnoses:
Lumbar magnetic resonance imaging (MRI) scan revealed a circular abnormal signal in the spinal canal at the level of L2. Pathological examination confirmed classic ependymoma.
Interventions:
The patient underwent tumor resection surgery.
Outcomes:
Postoperatively, the patient’s right lower limb soreness improved, and no new neurological deficits were observed.
Lessons:
Focal classic intradural extramedullary ependymomas near the conus medullaris are rare. Close follow-up with MRI of the craniospinal axis is necessary. Hormonal factors may influence the development of ependymomas in this unusual location. The appearance of these tumors on MRI and contrast-enhanced MRI scans is variable.
