S. Kurugoglu et al., Destructive diskovertebral lesions in ankylosing spondylitis: Appearance on magnetic resonance imaging, SOUTH MED J, 94(8), 2001, pp. 837-841
We report magnetic resonance imaging findings of diskovertebral lesions in
a case of ankylosing spondylitis mimicking metastatic and/or infectious dis
ease. Multiple hypointense areas were seen on TI-weighted images correspond
ing to hyperintense areas on T2-weighted images in dorsal, lumbar, and sacr
al vertebral bodies and the manubriosternal joint, with accompanying soft t
issue masses. Diagnosis was achieved through biopsy, regression of the para
vertebral soft tissue masses, later detection of bilateral sacroiliitis on
computed tomography, and presence of histocompatibility antigen HILA-B27.
