Abstract

Objective: To explore the MRI characteristics of hemangioblastoma of the spinal cord. Methods: MRI appearance of 12 spinal cord hemangioblastoma patients with surgically and pathologically proved were analyzed restrospectively. Results: In the 12 cases of spinal cord hemangioblastomas, 3 case had multiple lesions, one patient also had intracranial hemangioblastoma. The lesions were located in cervical spinal cord in 7 cases, thoracic spinal cord 3 cases, cervical thoracic segement in 1 case, thoracic lumbar segement in 1 case. MRI appearance: the signal on T1WI of the tumors showed iso-hypointense in contrast to the normal spinal cord, higher intensity(n=1) than blood; and mixed hyper-hypointense signal on T2WI. After enhancement, nodular tumors showed marked enhancement with distinct border on T1WI. The blood flow-void-sign(n=11) within and around the masses was seen on T2WI or on contrast scans. There were secondary syringomyelia or cystic changes, above or below the tumor in 10 cases. Conclusion: MRI is an efficient method in the diagnosis of spinal cord hemangioblastoma. It plays an important role in the diagnosis and differential diagnosis of hemangioblastoma.
