INTRODUCTION: A case of combined epiconus and cauda equina syndrome due to multilevel spinal canal stenosis of the thoracolumbar spine is reported. METHODS: A 76-year-old man with multilevel spinal canal stenosis of the thoracolumbar spine (Th11-12, L2-S) who showed symptoms of epiconus syndrome was reported. First, we performed anterior decompression and fusion at the thoracolumbar junction (decompression: Th11-12, fusion: Th10-L2), which ameliorated his symptom partially. However, he presented cauda equina symptoms. Then, he underwent posterior spinal decompression (L3-5) and fusion (Th12-L5). RESULTS: After anterior decompression, several symptoms disappeared. However, motor and sensory disturbance below L4 and bladder-bowel disturbance remained. We then performed a secondary operation. At three years' follow-up, he was able to walk with the aid of a cane. CONCLUSIONS: Combined epiconus and cauda equina syndrome due to multilevel spinal canal stenosis was treated by combined two-stage anterior and posterior decompression. In this case, multilevel decompression via anterior and posterior approaches was necessary to relieve the symptoms.
