Incidental Finding of Parasagittal Meningioma Following the Occurrence of Myoclonic Seizure after the Spinal Anesthesia

Abstract

In the present manuscript, an 87-year-old man, who was a candidate for knee joint replacement surgery due to severe osteoarthritis of the right knee, was case reported. He underwent neuroaxial anesthesia. Following spinal anesthesia with bupivacaine 0.5% in the fourth and fifth lumbar vertebra, the patient developed myoclonic seizures in the lower limbs and abdomen that lasted during the surgery, as well. Due to the continuation of the seizures, the necessary examinations were performed and an extra-axial tumor in the left parasagittal was detected in the patient’s brain imaging.
