Core tip: Midline, intraspinal cysts arise from facet joint degeneration. The lesions represent an important and often over-looked cause of back pain and other neurological symptoms. Radiographic identification of the fluid-filled sacs is particularly important in the setting of cauda equina syndrome, in which immediate surgical intervention is required in order to address the compressive lesion. Although the treatment of choice is a spinal decompression and resection, posterior fusions may prevent cyst recurrence.
