Meningitis is a rare complication after spinal anesthesia. We report 4 cases of meningitis occurred after spinal anesthesia. These meningitis were diagnosed during tow months and with 3 different operators. The first symptoms appeared 4 to 6 hours after surgery and were represented especially by headaches and fever.

The exactly cause of these meningitis remained unknown and an insufficient asepsis was the principle risk factor found in all cases. Prevention of this risk consists on hygienic rules and perfect skin disinfection
