The initial MRI showed numerous small (2-3 mm), contrast-enhancing intrathecal lesions involving the cauda equina nerve roots at the levels of the L2 and L3 vertebrae [Figure 1].
Intraoperative photograph demonstrating multiple small mulberry-like vascular malformations intimately involved with the nerve roots of the cauda equina. These vascular malformations are associated with dilated vessels, and most likely represent multiple radiation-induced cavernous malformations
