Abstract
ABSTRACT Facet joint ganglia are benign cystic lesions located adjacent to a facet joint. The majority is asymptomatic. However, can cause important low-back pain and radiculopathy. Neurogenic deficit, claudication, and cauda equina syndrome have also been reported. The authors report two cases of acute low back pain with bilateral sciatica, dorsal foot dysesthesia, and hallux dorsiflexion/extension deficit, due to the presence of encapsulated cysts adjacent to the facet joints causing a significant reduction of the spinal canal. Urgent surgical decompression was performed in both patients with an uneventful recovery. Symptomatic facet joint ganglia is a highly unusual cause of back pain, although it can present with acute onset of bilateral sciatica and canal stenosis requiring urgent surgical decompression. This paper highlights facet joint synovial as a differential diagnosis of lumbar pain and describes two different surgical approaches with good outcomes. Level of Evidence IV; Case Series.
