(Left) Unenhanced, sagittal, T1-weighted MRI at the thoracolumbar junction. A metastatic tumor within the conus medullaris is isointense to cord. Above and below the tumor, a thin, tapered, hypointense area represents a syringomyelic cavity or necrotic spinal cord tissue. (Center) Unenhanced, sagittal, T2-weighted MRI. The tumor remains nearly isointense to cord. The surrounding necrotic tissue or syrinx becomes hyperintense. (Right) After the intravenous administration of contrast, a sagittal, T1-weighted MRI shows homogeneous enhancement of the tumor but not the syrinx or necrotic tissue above and below it.
