Abstract
A case of capillary hemangioma of the cauda equina is reported. Myelography with water-soluble contrast material showed a complete obstruction of the contrast column at the L1–L2 level. Neither plain nor intravenously enhanced CT revealed the tumor. Spinal angiography showed a feeding vessel to the tumor and a faint tumor stain. Magnetic resonance imaging (MRI) showed a mass lesion of slightly higher than cauda equina intensity, which was clearly enhanced with Gd-DTPA. MRI, especially Gd-DTPA- enhanced study, plays the most important role in the diagnosis of a spinal capillary hemangioma. Spinal angiography was interesting in showing a tumour with a capillary blush.
