FIG 1. A–C, Sagittal T1-weighted images (TR 366/TE 14), from right to left, showing a right paraspinal mass with predominant high T1 signal intensity and interspersed areas of intermediate signal intensity. The mass extends through the intervertebral foramina, causing widening of the foramina.
D, Axial T1-weighted image (TR 366/TE 14) showing a right paraspinal mass that extends through the intervertebral foramina causing widening of the foramina and scalloping of the posterior margin of the vertebral body.
E, Axial T2-weighted fast spin-echo image (TR 3400/TE 110) showing mild effacement of the right lateral aspect of the thecal sac without any significant compression.
F and G, Sagittal fat-suppressed postcontrast T1-weighted images (TR 366/TE 14) show that the mass follows the signal intensity of the subcutaneous fat. There are interspersed areas of enhancement.
