        This paper reports a case of postoperative pseudomeningocele, which was not
diagnosed initially with clinical data alone; the condition was caused by an
inadvertent meningeal tear that occurred during spinal surgery. Pseudomeningocele
formation is a rare postoperative complication of spinal surgery characterized by
the extradural accumulation of cerebrospinal fluid following extravasation through
an inadvertent dural tear.
A 69-year-old woman had undergone laminectomy and posterolateral fusion at the
L3-L5 level 7 years previously, for spondylolisthesis with spinal stenosis syndrome;
the postoperative course was uneventful. Six years after the surgery, the patient
experienced increasingly severe low back pain radiating to both gluteal regions.
After prolonged but unresponsive conservative treatment, a large
pseudomeningocele at the L2-L3 level was identified by myelography. The findings
of MRI supported the diagnosis of pseudomeningocele. Surgery via the posterior
approach exposed the pseudomeningocele after a complete laminectomy of L2-L4.
The pseudomeningocele was excised 7 years after the initial operation. Complete
recovery and excellent remission of symptoms was noted at 6 months after the
surgery.
Pseudomeningocele must always be considered as a cause of chronic back pain in
patients who have undergone previous lumbar surgery, no matter how many years
after the surgical procedure the symptoms may occur. |
