Acute sciatica and progressive neurological deficit secondary to facet synovial cysts: A report of two cases (original) (raw)

To describe two patients with lumbar facet synovial cysts causing sciatica and progressive neurological deficit. A 52-year-old female with bilateral sciatica and a neurological deficit that progressed to a foot drop; and a 54-year-old female with worsening sciatica and progressive calf weakness were seen at a major tertiary care centre. Diagnostic imaging studies revealed the presence of spinal nerve root impingement by large facet synovial cysts. Activity modification, gabapentinoid and non-steroidal anti-inflammatory medications were unsuccessful in ameliorating either patient's symptoms. One patient had been receiving ongoing lumbar chiropractic spinal manipulative therapy despite the onset of a progressive neurological deficit. Both patients eventually required surgery to remove the cyst and decompress the affected spinal nerve roots. Patients with acute sciatica who develop a progressive neurological deficit while under care, require prompt referral for axial imaging and su...
