Purpose : To evaluate the MR imaging findings of ankylosing spondylitis involvins the
thoracolumbar spine.
Materials and Methods : We retrospectively analyzed MR imaging findings in ten
patients with ankylosing spondylitis involving the thoracolumbar spine. All were male
and ranged in age from 24 to 47(mean, 33)years. MR images were obtained using a
1.5T imager, and signal intensity changes of vertebral bodies were evaluated in sagittal
T1- and T2-weighted images. Plain radiogrsphic findings were also evaluated .
Results : On T1-weighted images, five cases showed focal high-, two cases low-, two
cases high and low-, and one case iso-signal intensities at the corners and/or along the
anterior borders of the vertebral bodies. On T2-weighted imates, seven cases showed
focal high-and three, iso-signal intensities in those areas of the vertebral bodies. In one
case which showed focas high signal intensity on T1-weighted images and iso-signal
intensity on T2-weighted images, multiple Schmorl's node were seen in thoracolumbar
spines. In all cases, signal intensity changes were more prominent in anterior portions of
the vertebral bodies. The shapes of abnormal signal intensities were vertical wedge,
vertical band, and round dot. Plain radiographs showed bamboo spone in three Schmorl's
node in one, and no abnormal findings in three.
Conclusion : characteristic MR imaging findings of ankylosing spondylitis involving the
thoracoumbar vertebral bodies were focal intensity changes changes at the corners and
along the anterior borders or the vertebral bodies.(J Korean Radiol Soc 1998; 38
:351-357)
