A 70-year-old female underwent sequential CT scans to monitor a previously discovered descending thoracic aortic aneurysm. In November 2004, the aneurysm measured slightly more than 6 cm in maximum AP and transverse dimensions. In June 2005 the aneurysm was much larger, measuring 9.1 cm in the AP dimension x 10.1 cm in the transverse dimension. There was interval development of marked erosive changes of the left lateral aspects of the T8 and T9 vertebral bodies, which were adjacent to the aneurysm.

Vertebral body erosion is an unusual complication of an enlarging aortic aneurysm, with only a few reported cases in the literature.
