title: Percutaneous Rupture of a Symptomatic Facet Joint Synovial Cyst Using 2-Needle Distention.
abstract: OBJECTIVE
  This case report calls attention to an alternative approach for management of a symptomatic facet joint synovial cyst. We describe a patient with a symptomatic facet joint synovial cyst who failed an attempted percutaneous rupture using a single-needle technique. This patient was subsequently successfully managed with percutaneous rupture using a 2-needle technique.
  
  
  METHODS
  A 60-year-old woman presented with low back pain, right lower extremity pain, and paresthesias. Magnetic resonance imaging revealed a right L5-S1 facet joint cyst, which compressed the right L5 nerve root. Before presentation, the patient failed an attempted single-needle percutaneous rupture. The decision was made to proceed with percutaneous rupture using a 2-needle technique. A 22-gauge needle was inserted into the right L5-S1 facet joint, and a Tuohy needle was inserted directly into the cyst through an interlaminar approach. A solution of methylprednisolone and hyaluronidase was simultaneously injected through both needles, and the cyst was continuously distended until rupture was achieved. Rupture was confirmed by injecting contrast into the facet joint and visualizing a normal epidurogram. The patient reported significant pain relief immediately after the procedure. At 4-month follow-up, the patient reported continued pain relief and denied any radicular symptoms.
  
  
  CONCLUSIONS
  Percutaneous rupture of a symptomatic facet joint synovial cyst using a single-needle technique has been validated as an efficacious form of management. In a select group of patients who fail single-needle percutaneous rupture, a 2-needle approach for percutaneous facet cyst rupture may be considered as an option for management.
