Lu et al evaluated previous clinical studies to identify risk factors for postoperative seizures in a patient who has undergone surgery for a meningioma. These can help to identify a patient who may require more aggressive management. The authors are from the Mayo Clinic.

Patient selection: status post surgery to remove a meningioma


Outcome: seizure following the seizure


Predictors of postoperative seizures:

(1) preoperative seizure history (HR 3.5)

(2) non-skull base location (HR 2.4)

(3) postoperative complications (HR 4.0)

(4) meningioma recurrence after the surgery (HR 3.7)


The risk increases with the number of risk factors present.
