MR Features in Spinal Hemangioblastomas

Objective To study the MR findings of spinal hemangioblastomas. Meth- ods MR imagings in 6 patients with spinall Hemangioblastomas proved pathologically were reviewed retrospectively. Conventional and contrast-enhanced MR scaning were performed in all patients. Results The six patients all had a solitary tumor, the tumors were located at the posterior aspect of the spinal cord, Two tumors was in the cervical region, one in the medullo-cervical region, three in the thoracic region. Five tumors were solid,One was cystic with a mural nodule, The intensity of tumors were mainly isointense on T1 WI and hyperintense on T2WI, Intense enhancement were found in the solid tumors and one mural nodul,5 cases were accompanied by syrinx and vascular flow voids in or around tumors. Conclusion There are characteristic MR feartures in spinal Hemangioblastomas,which are useful to the correct diagnose.
