title: Ultrasound-guided facet joint injection to treat a spinal cyst.
abstract: Lumbar spinal cysts often present with backache and may be accompanied by lower extremity weakness as well as radiation pain if root compression occurs. The treatment regimens include anti-inflammatory drugs, physical therapy, procedures guided by fluoroscopy or computed tomography, and surgery. We report the case of a patient with a symptomatic lumbar spinal cyst at the L4-L5 facet joint. The symptoms immediately remitted after ultrasound-guided steroid-lidocaine injection into the L4-L5 facet joint. Magnetic resonance imaging follow up 4 months after injection showed complete resolution of the cyst.
