They may be congenital or acquired following trauma or spinal procedures. Although slow-growing, their mass effect can cause progressive neurological symptoms. Resection remains the mainstay of treatment, but they may recur when complete removal is limited by adherence to neural structures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>OBSERVATIONS<\/jats:title>\n                    <jats:p>A 71-year-old female with prior lumbar surgery presented with back pain and radiculopathy after multiple falls.
