Intradural Extramedullary Capillary Hemangioma with Long Segment of Transient Cord Edema: A Case Report

that are believed to be hamartomatous proliferations of vascular endothelial cells. They are bright red to blue in color, sharply demarcated from the surrounding skin or mucosal tissue, and usually located on the head and neck in childhood (1). Spinal intradural extramedullary capillary hemangiomas are extremely rare and only a few cases have been reported (2-8). They appear isointense or hypointense relative to the spinal cord on T1weighted images, isointense or slightly hyperintense on T2-weighted images, and exhibit a strong homogenous enhancement on contrast-enhanced T1-weighted images. To our knowledge, intradural extramedullary capillary hemangiomas with a long segment of transient T2 hyperintensity in the spinal cord have not previously been reported. We present a rare case of thoracic intradural extramedullary capillary hemangioma that was accompanied by a long segment of transient T2 hyperintensity in the spinal cord.
