Lumbar Facet Joint Synovial Cysts: Does T2 Signal Intensity Predict Outcomes after Percutaneous Rupture?

摘要

BACKGROUND AND PURPOSELumbar facet synovial cysts are a cause of back pain and radiculopathy with facet joint degeneration, the most common cause for cyst formation. Typically, LFSCs are T2 hyperintense on MR imaging, but the signal intensity is variable. Treatment options include percutaneous rupture and surgical resection. This study evaluates the relationship between LFSC signal intensity on MR imaging and outcomes as it relates to percutaneous rupture success and need for subsequent surgery.
