Intradural cervical chordoma. Case report.

We describe a rare case of an intradural spinal chordoma. Only two cases have been previously reported and it is the second case diagnosed with MRI. A 65-year-old man presented with progressive disturbance of gait and weakness in the lower extremities. MRI revealed a intradural C6-C7 isointense mass, on T1- and T2-weighted images. The lesion enhanced after injection of gadolinium. The lesion was totally removed without difficulty by a C6-D1 laminectomy. Microscopic examination of the tumor revealed a chordoma. This is the third case in the literature of an intradural spinal chordoma. The appearance of this tumor with MRI may be similar to the chordomas of other locations.
