The growth of a pre-existing lumbar juxta-facet cyst after a laminectomy is a rare
condition. Here we report a 60-year-old woman who presented with acute severe
buttock pain and recurrent left L5 radicular pain one month after a laminectomy
for L4-5 spinal stenosis and a herniated intervertebral disc. Magnetic resonance
imaging (MRI) revealed that a cyst extending from the facet joint to the spinal canal
compressed the left L5 nerve root. Without surgical intervention, the patient’s
condition improved after analgesic medication, bed rest and the fitting of a lumbar
corset. At the 6-month follow-up, the MRI showed spontaneous resolution of the cyst
with no narrowing of the spinal canal or root compression. The pathogenesis of the
cyst could have been related to the degenerative mobile spine after the
decompressive laminectomy. This case demonstrates that post-laminectomy
recurrence of radiculopathy may result from the growth of a pre-existing juxta-facet
cyst. Furthermore, conservative treatment may be the first therapeutic option
because spontaneous resolution of such a cyst is known to be possible. |
