MR Imaging of Non-Infectious Inflammatory Diseases of the Spine 2014

Category General Spine Vikas Datta Steven Meyers Purpose This exhibit will aim to familiarize the practicing radiologist with the characteristic MR imaging appearances of the wide array of non-infectious inflammatory diseases which can affect the vertebrae, dura, subrarachnoid space, and/or spinal cord. Materials & Methods - Brief overview of the various non-infectious inflammatory diseases involving the vertebrae, thecal sac and spinal cord. - MR imaging features of the various non-infectious inflammatory diseases of the spine, with emphasis on helpful imaging characteristics to aide in differentiation of disease processes. • Interesting case presentation of atypical presentations and rare pathology. Results A wide spectrum of non-infectious inflammatory diseases affect the spine, both the spinal cord and spinal column. Examples of inflammatory disease of the spinal cord which will be explored include: Guillain Barre Syndrome, arachnoiditis, multiple sclerosis, neuromyelitis optica, acute disseminated encephalomyelitis, juvenile xanthogranuloma, transverse myelitis, radiation myelopathy, sarcoidosis and lupus related myelopathy. Non-infectious inflammatory diseases of the spinal column, which will be discussed, include but are not limited to: ankylosing spondylitis, calcium pyrophosphate deposition disease, gout, rheumatoid arthritis and sarcoidosis. Conclusion A wide array of non-infectious inflammatory diseases affect the spine, both the spinal cord and spinal column. The imaging similarities of the various disease processes present a diagnostic challenge to the practicing radiologist. Familiarity with imaging characteristic of the variety of non-infectious inflammatory diseases of the spine can help in narrowing the differential and in facilitating accurate diagnosis. MRI is invaluable in identifying the location and extent of inflammatory spinal disease. This exhibit will aim to familiarize participants with the wide array of non-infectious inflammatory diseases of the spine and their characteristic imaging appearances. References DeSanto J, Ross JS.
