Abstract:
We report magnetic resonance imaging findings of diskovertebral lesions in a case of ankylosing spondylitis mimicking metastatic and/or infectious disease. Multiple hypointense areas were seen on T1-weighted images corresponding to hyperintense areas on T2-weighted images in dorsal, lumbar, and sacral vertebral bodies and the manubriosternal joint, with accompanying soft tissue masses. Diagnosis was achieved through biopsy, regression of the paravertebral soft tissue masses, later detection of bilateral sacroiliitis on computed tomography, and presence of histocompatibility antigen HLA-B27.
