Summary
A rare mature teratoma was found in the cauda equina of a 76-year-old female. Surgical removal resulted in no new neurological deficits, with some symptom improvement.
Area of Science:
- Neurosurgery
- Neurology
- Oncology
Background:
- Intradural lesions within the cauda equina are rare, particularly in elderly patients.
- Teratomas, a type of germ cell tumor, can occur in the spinal canal, presenting unique diagnostic and surgical challenges.
Observation:
- A 76-year-old female presented with chronic sacral and gluteal paresthesias and hypoesthesias.
- Magnetic resonance imaging revealed an intradural lesion at the L2-L3 vertebral levels within the cauda equina.
- Surgical exploration identified a solid, heterogeneous lesion entangled with nerve roots.
Findings:
- Intraoperative aspiration yielded melanocytic material.
- Histopathological analysis confirmed a mature teratoma, a germinal neoplasia lacking immature neuroepithelium or malignant components.
- The patient experienced no new neurological deficits post-surgery.
Implications:
- This case highlights the importance of considering mature teratomas in the differential diagnosis of intradural spinal lesions, even in older adults.
- Surgical resection is a viable treatment option, potentially leading to symptom improvement.
- Complete resection without neurological compromise is achievable with meticulous surgical technique.
