Post-traumatic spinal synovial cyst with spondylolysis: CT features.
A spinal synovial cyst at L2-L3 produced obstruction at myelography and simulated an intraspinal tumor on CT. The CT recognition of bilateral spondylolysis of L3 suggested the possibility of a mobile posterior arch of L3 and associated synovial herniation. This was verified at surgery.
