Summary

This summary is machine-generated.

Sciatica pain resolved after surgery but returned due to nerve entrapment by a pseudomeningocele, a rare complication. Surgical repair led to an uneventful recovery, highlighting the importance of considering this diagnosis.

Area of Science:

Neurosurgery
Spinal Surgery
Neurology

Background:

Sciatica is commonly caused by lumbar disc herniation.
Surgical intervention often provides significant pain relief.
Postoperative complications require careful diagnosis and management.

Observation:

An elderly woman experienced sciatica relief after disc herniation surgery.
Recurrent severe pain and foot palsy developed weeks later.
Lumbar MRI showed no recurrent disc herniation.

Findings:

Surgical exploration revealed intermittent nerve entrapment due to a dural tear and pseudomeningocele.
This is a rare cause of sciatica, distinct from recurrent disc herniation.
Prompt diagnosis and surgical repair of the dural tear and pseudomeningocele were performed.

Implications:

Nerve entrapment by a pseudomeningocele is a rare but critical differential diagnosis for postoperative sciatica.
Subtle MRI findings can mask this condition, necessitating surgical exploration.
Timely surgical intervention is crucial to prevent permanent neurological deficits like paralysis.
