@entity2477 ( @entity2477 ) is a rare @entity455 , consisting of abnormal, dilated, and packed sinusoidal vascular channels without interposed nervous tissue. CAs of the cauda equina are exceedingly rare and have been previously reported in the literature as case reports. The aim of this study was to discuss the clinical presentation and the outcomes of microsurgery for these rare lesions. We retrospectively reviewed the records of 10 @entity1 who underwent microsurgery for CAs of the cauda equina. All @entity1 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 @entity2477 was rare. Gross total resection was achieved in all cases. All @entity1 were followed up, with a mean duration of 41.1 months. Long-term neurological function was improved in nine @entity1 and remained stable in one @entity1 . No recurrence was observed on MRI. CAs should be considered in the differential diagnosis of @entity1971 . Because of the excessive vascularity of CAs, en bloc resection is recommended. For symptomatic @entity1 , early surgery should be performed before @entity51 deteriorate.
