Abstract

Spinal cord subependymomas (SE), either intramedullary (IM) or extramedullary (EM) are rare, as are multiple SE. We describe one case of each of these unusual presentations diagnosed mainly with MRI. On MRI, the masses were well demarcated, heterogeneous or homogenous, isointense or giving low signal relative to normal white matter on T1-weighted images and high signal on T2-weighted images. These masses demonstrated either no enhancement or pronounced heterogeneous enhancement. Gross total removal was performed in two cases. The IM SE recurred 7 years after surgery.
