The clinical presentation includes neurogenic claudication, gait disturbance, myelopathy and polyradicuopathy in both upper and lower limbs. A 43-year-old female presented with predominant low back pain with right S1 radiculopathy leading to diagnosis of synovial facet cyst of lumbar spine. She was managed surgically after medical treatment failed. After 1 week post operatively, she presented with severe neck pain with left radiculopathy. MRI revealed acute on chronic cervical prolapsed intervertebral disc, cervical decompression surgery proceeded. Post operative improvement was noted on follow up. We report a case of tandem spinal stenosis, which both of the pathologies were managed with endoscopic approach.展开更多
