title: A rare case of extramedullary-intradural hemangioblastoma in the thoracic spine.
abstract: STUDY DESIGN.: Case report. OBJECTIVE.: To present a rare case of extramedullary-intradural hemangioblastoma in the thoracic spine and to review the literature on this condition. SUMMARY OF BACKGROUND DATA.: Spinal hemangioblastoma is rare, and moreover, there is seldom purely extramedullary-intradural hemangioblastoma of the spinal cord and there are few reports on histopathological features of spinal hemangioblastoma. METHODS.: A 65-year-old Japanese woman presented with gait disturbance and numbness below the trunk that had gradually worsened, and finally she was unable to walk by herself. Physiologic and neurologic examinations at admission revealed severe transverse neurologic defects, with no sign of von Hippel-Lindau's disease. Radiologic methods showed an extramedullary-intradural mass at Th4-5. A diagnosis of extramedullary-intradural spinal tumor was done, total tumorectomy was performed with recapped laminoplasty. RESULTS.: The patient's neurologic condition gradually improved after the operation. The immunohistopathological findings revealed the diagnosis of hemangioblastoma. CONCLUSION.: A rare case of extramedullary-intradural spinal hemangioblastoma was reported. The immunohistopathological findings were helpful for making a final diagnosis.
