Background And Purpose
Method
We retrospectively reviewed the records of 10 patients who underwent microsurgery for CAs of the cauda equina. All patients had performed pre- and postoperative magnetic resonance imaging (MRI). CAs of the cauda equina generally exhibited mixed intensity on T1- and T2-weighted images. Contrast-enhanced T1-weighted images showed heterogeneous enhancement. The hemosiderin ring which surrounded the cauda equina CA was rare. Gross total resection was achieved in all cases. All patients were followed up, with a mean duration of 41.1 months.
Conclusion
CAs should be considered in the differential diagnosis of cauda equina tumors. Because of the excessive vascularity of CAs, en bloc resection is recommended. For symptomatic patients, early surgery should be performed before neurological deficits deteriorate.
Main results
Long-term neurological function was improved in nine patients and remained stable in one patient. No recurrence was observed on MRI.
