Marked reduction in the anterior heights of T8 and T9 vertebral bodies showing abnormal outline, irregular opposing end plates, and near total obliteration of the intervening disc space. They show diffusely low T1 and bright T2 and STIR signals with contrast uptake in the post-contrast series.
They are also surrounded by an irregular para-spinal and intraspinal soft tissue component that exhibits heterogeneous low T1 and bright T2 signal intensity with heterogeneous contrast uptake in the post-contrast series where it also shows areas of ring enhancement.
The intraspinal component is seen effacing the ventral subarachnoid space and indenting the thoracic cord at the T8-9 level. The opposing spinal cord shows bright T2 and STIR signals within.
