초록
In advent of high-resolutional CT and MRI, it is not so difficult to detect the lumbar synovial cyst, however the unusual disease should be included in the differential diagnosis of cauda equine compression syndromes. The case of a 55-year-old man who had a low back pain and severe radiating pain on both legs showed a retrolisthesis at L3-4 and L4-5 and epidural enhancing mass just around L4-5 facet joint on MRI. Microscopically a lining of synovial tissue was demonstrated. After surgery of the total resection of synovial cyst and stabilization, the patient's presenting symptoms were improved.
