MRI findings
Image 1: Sagittal T1WI: L1-L2 solid tumor isointense to cord with a caudal cyst pushing the conus upwards.
Image 2: Sagittal T2WI: The solid nodule shows heterogeneous low signal intensity with well defined contours. The associated cyst is hyperintense. Posterior and upwards displacement of the conus is best demonstrated.
Image 3: Sagittal Gd T1WI: The tumor enhances intensely although heterogeneously following contrast administration.
