Minimally invasive CT guided treatment of intraspinal synovial cyst

Abstract

Background

Intraspinal synovial cysts of vertebral facet joints are uncommon cause of radicular pain as well as neurological deficits. They can be managed both conservatively and surgically.

Case report

A 77-year old polymorbid patient presented with bilateral lumboishialgia which worsened during the course of time and did not respond to conservative treatment. A diagnosis of intraspinal synovial cyst was made using the magnetic resonance imaging (MRI).

Percutaneous computer tomography (CT) guided injection with installation of local anaesthetic together with corticosteroid and rupture of the cyst was sucessfully used.

A month after procedure his pain improved, the usage of analgesics diminished and his over-all quality of life improved as well.

Conclusions

Percutaneous CT - guided lumbar synovial cyst treatment is safe and reliable alternative to surgical treatment in polymorbid patients with radiculopathy who are not able to tolerate general anaesthesia and operation.
