Lumbar radicular pain caused by epidural varices

ABSTRACT

Low back pain and sciatica are mainly caused by herniated lumbar disc and spondylotic lumbar canal stenosis. However, some rare entities such as lumbar epidural venous anomalies can result in acute low back pain and sciatica, among which epidural varices are less encountered. It can be not only idiopathic but also secondary to some vascular malformations. In this study, we report two cases of lumbar epidural varices presenting with low back pain and acute severe sciatica
