1 Sagittal MR images of the lumbar spine reveal the heterogeneous appearance of the mass indicative of a variety of components. Sagittal MR images of the lumbar spine reveal the heterogeneous appearance of the mass indicative of a variety of components. A, On T1-weighted image, most of the mass is hyperintense (arrowhead) with a hypointense mural nodule (arrow).B, On T2-weighted image, the mass shows mixed signal intensities (arrow). The cystic lesion within the spinal cord proximal to the mass is quite visible (arrowhead).C, After administration of gadopentetate dimeglumine, T1-weighted image shows the intense enhancement of the nodular component (arrow).D, Axial T1-weighted image shows the mass (arrow) within the spinal canal, with leftward displacement of the conus medullaris.
