RAPIDLY PROGRESSIVE NEUROPATHIC ARTHROPATHY IN SYRINGOHYDROMYELIA - RADIOGRAPHIC AND MAGNETIC-RESONANCE-IMAGING FINDINGS

A rapidly progressive neuropathic shoulder joint in a patient with syr ingohydromyelia is presented. He developed marked destruction of the s houlder joint over 5 weeks. The MRI findings in the pre- and post-reso rptive phases of the arthropathy are presented for the first time. Low signal intensity areas are observed in the medullary cavity of the bo ne on bath T1- and T2-weighted spin-echo images even before the actual resorptive process starts. Additional major findings are the joint ef fusion and synovial thickening.
