BACKGROUND: @entity11665 is an uncommon disorder characterized by the formation of multiple cartilaginous nodules in the synovium of the facet joint. It most commonly affects large joints such as hip or shoulder. Commonly seen features are bony erosion and @entity730 . @entity11665 is rare in the spine and there are few previous reports of extension into the spinal canal. CASE DESCRIPTION: A 58-year-old @entity1 presented with a 2 year history of progressive @entity1183 without objective weakness. A several month course of conservative management, including physical therapy, failed to alleviate symptoms. Magnetic resonance imaging of the cervical spine demonstrated the erosion of the right facet @entity2244 joint with listhesis and foraminal enlargement secondary to a lesion. Treatment was offered to the @entity1 in the form of surgical resection. The lesion was removed in piecemeal fashion using curettes and Cavitron ultrasonic surgical aspirator. Histological examination demonstrated atypical well-differentiated @entity705 . CONCLUSION: This @entity1 had an uncomplicated postoperative course and experienced complete resolution of right @entity1109 . @entity11665 may compromise cervical spinal cord and nerve roots if it extends into the spinal canal. Although it remains rare, it should be included in the differential diagnosis for @entity614 and @entity602 . Surgical resection is a viable treatment option for symptomatic @entity1 with this pathology. In some cases, adequate resection may necessitate stabilization with instrumentation.
