Synovial cysts of the spine are combined with osteoarthritic disease of the facets. Normally they arise at the level L4-L5 or L5-S1 and may contribute to central canal stenosis.
On MR the cyst is isointense or slightly hyperintense with respect to CSF on T1-weighted images. On T2-weighted images the cyst is hyperintense.
