Background: We present a series of 9 adults submitted to radical microsurgical resection of cauda equina ependymoma of the myxopapillary type during an 11-years period (1994-2004). No recurrence was noted at the follow-up (6 months – 10 years).
Material and methods: 4 of the patients were male and 5 were female. Average age was 44 years (the younger was 21 and the older was 58). The main clinical presentation was persistent lumbar pain. All 9 patients had a homogenously enhancing cauda equina – filum terminale tumour. In all cases origin of tumour was at the point of emergence of filum terminale from the conus medularis. In 3 cases the tumour was infiltrating the conus medularis as well. Patients were submitted to radical microsurgical resection via lumbar laminotomy or laminectomy using ultrasonic aspirator and CO2 Laser.
Results: There were no remarkable complications. In 2 male patients there was a temporary bladder dysfunction for 1-2 weeks postoperatively. Histology was myxopapillary ependymoma. No one was submitted to post-op radiotherapy. The follow-up is clinical examination and GD-enhanced MR imaging at 6 months, 1 year, 2 years, 4 years, 6 years, 8 years and 10 years post-op. One patient was lost from the follow-up 2 years after the operation. No recurrence has been noted.
Conclusions: Complete microsurgical resection is the treatment of choice for cauda equina myxopapillary ependymomas. After total resection, there is no need for post-op radiotherapy.
