Postlaminectomy lumbar pseudomeningocele with nerve root entrapment: a case report with review of literature.

Pseudomeningocele is a rare but well-recognized complication of lumbar surgery. Most of the patients tolerate the presence of the cyst well, however, some present with back pain and spinal claudication, presumably due to neural compression. We report a case who presented with radicular symptoms and signs after disk surgery. The cause of his pain was nerve root herniation into large pseudomeningocele. The diagnosis was made by magnetic resonance imaging. The patient underwent surgery for the pseudomeningocele with reduction in the nerve root into the dural canal and primary closure of the dural defect. Postoperative results were gratifying.
