MRI features of spinal ganglioglioma.

Spinal cord ganglioglioma is a rare tumor most often encountered in the first three decades. Scanty computed tomography (CT) reports on the tumor describe it as a hypodense or cerebrospinal fluid (CSF) dense area with little contrast enhancement despite its solid nature. We report two cases of spinal ganglioglioma both involving almost the whole spinal cord. On magnetic resonance imaging (MRI), the tumors appear hypointense to the spinal cord on T1 and hyperintense to the cord on T2 images, and were mainly solid at exploration. It is important to recognize these tumors as long survival can be achieved after surgical resection.
