Vertebral synovial osteochondromatosis with compressive myelopathy.

Abstract

A case report of vertebral synovial osteochondromatosis with compressive myelopathy. To describe the clinical, radiologic, and histopathologic features of vertebral facet synovial osteochondromatosis with compressive myelopathy. There has been only one previously reported case of synovial osteochondromatosis affecting the vertebral facet joint and no previous report of associated compressive myelopathy. The case history, radiology, surgical findings, and histopathology are reviewed. Vertebral facet synovial osteochondromatosis is a potential and readily manageable cause of spinal cord compression. Synovial osteochondromatosis of the vertebral facet joint should be considered as a cause of compressive myelopathy.
