Extramedullary Cavernous Hemangioma with Intradural and Extradural Growth and Clinical Symptoms of Brown-Séquard Syndrome: Case Report and Review of the Literature.

Abstract

Primary spinal tumors are rare. Symptoms depend on the size and location of the tumor. A patient presented with a rare clinical finding, Brown-Séquard syndrome. The symptoms were caused by an extramedullary tumor compressing on the thoracic spinal cord. Pathologic examination showed cavernous hemangioma with growth both intradurally and extradurally. This is an extremely rare finding; to our knowledge, only 1 case report has been published before in which a spinal cavernous hemangioma had intradural and extradural growth. The clinical symptoms of Brown-Séquard syndrome have not been described before in the findings of spinal cavernous hemangiomas.
