Symptomatic pneumocephalus: A rare complication of discal herniation's surgery

Abstract

Context: We report the case of a 40-year-old woman with no pathological history, operated from an L4-L5 disc herniation by a left unilateral approach. The dura mater enveloping the left L5 root was accidentally injured at its lateral face causing a breach with CSF leakage. This breach could not be sutured. A few hours after waking, the patient presented an agitation followed by three generalized tonico-clonic seizures. Cerebral imaging revealed pneumocephalus. The patient was hospitalized in an intensive care unit. The symptoms gradually faded and the patient was discharged 3 days after surgery.

Findings: Pneumocephalus is defined by the presence of air inside the skull. The symptoms of pneumocephalus are generally non-specific and varied, and this complication should also be kept in mind to prevent potentially severe course. The prevention of postoperative pneumocephalus depends on a well-defined strategy in the case of iatrogenic dural tear.

Conclusions: Symptomatic pneumocephalus is a very rare complication in the course of lumbar surgery. Conservative therapy may be appropriate even in severe symptomatic manifestations.
