Abstract: Objective To summarize the MRI findings of spinal paraganglioma,in order to improve the diagnostic accuracy of imaging. Methods The MRI findings of 6 patients with spinal paraganglioma were retrospectively reviewed.All cases were proved by pathology.Results All 6 cases of spinal paraganglioma were located in lumbar spinal canal.There were serpentine vessels shade observed above the tumor in 5 cases.Two cases with smaller size of lesions exhibited as homogeneous signal intensity with homogenous enhancement. The other 4 cases with larger size of tumors exhibited as heterogeneous signal intensity because of intratumoral cystic change,hem-orrhage and hemosiderin deposit at the margin of the tumor.Conclusion Serpentine vessels above the tumor can be seen in spinal paragangliomas.Intratumoral cystic change and hemorrhage,hemosiderin deposit at the margin of the tumor are the MRI character-istics of spinal paraganglioma.
