Intraspinal Facet Cysts (Synovial Cysts) are fluid filled- round structures with a smooth border that develop along the facet joint along the spine. Synovial cysts develop as a result of articular tissue protruding due to facet joint arthritic changes and spinal instability. On MRIs and CT scans, synovial cysts are seen next to degenerative facet joints on the back side (dorsal). Cysts can also develop along the front (ventral) side of the spine and protrude into the intervertebral foramen, lateral recess, or lateral spinal canal. This formation leads to compressions of an existing nerve root in the foramen or descending nerve root in the lateral recess causing severe neuropathic and radicular pain. The best treatment for this type of spinal pain are NSAIDs. If pain continues to progressively get worse, a consult with a neurosurgeon is necessary for surgical removal.
