  		FIG 1. 66-year-old woman with lower back pain.

A, T1-weighted (550/12 [TR/TE]) sagittal MR image shows a well-defined, oval mass at the dorsal aspect of the T8–T9 level (arrows). The signal intensity of the mass is isointense with the spinal cord.

B, Contrast-enhanced T1-weighted (550/12) sagittal MR image shows homogenous, intense enhancement of the mass (arrows).

C, On T2-weighted (3600/112) sagittal MR image, the signal intensity is hyperintense relative to the spinal cord (arrows). Note the associated diffuse cord edema (arrowheads).

D, On contrast-enhanced T1-weighted (874/12) axial MR image, the spinal cord is markedly compressed by the posterolaterally located mass (arrows).

E, Low-power photomicrograph shows the tumor to be composed of variably sized but relatively small capillaries (asterisks), pericytes (arrows), and some stromal cells (fibroblasts) (arrowheads) (hematoxylin-eosin, original magnification x100).
