    AbstractThe authors present a case of multiple radiation-induced cavernous malformations of the cauda equina in a patient with a remote history of testicular cancer and extended field radiation therapy. Magnetic resonance imaging (MRI) demonstrated multiple nodular areas of enhancement coating the nerve roots of the cauda equina, mimicking an aggressive leptomeningeal process such as carcinomatous or infectious meningitis. Biopsy of one of these lesions revealed ectatic vascular channels devoid of intervening neuroglial tissue consistent with cavernous malformation.Copyright © 2011 by the American Society of Neuroimaging.
