Intradural extramedullary hemangioblastoma differentiated by MR images in the cervical spine: a case report and review of the literature.
We report a rare case of hemangioblastoma existing in the intradural extramedullary location diagnosed by magnetic resonance imaging (MRI) examination alone. A 46-year-old man gradually developed numbness in his lower extremities. MR images revealed a tumor shadow located posterior to the spinal cord at C5-C7. Small signal void shadows were continuously observed from C1 to C5 in the region cranial to the tumor, indicating the presence of enlarged vessels. Under microscopic observation, the tumor with accompanying vessels was resected totally via hemilaminectomy. The postoperative course was uneventful, and MR images obtained 4 months after the operative procedure demonstrated total removal of the tumor and the abnormal vessels. In this case, recognizing the abnormally enlarged vessels outside the tumor mass preoperatively led us to the correct diagnosis on MR images.
