A 25 years old pregnant woman had a painful labor in her 38th week of pregnancy. Because of a previous delivery by a cesarean section, she underwent a second cesarean section. Her past medical and family history was unimportant. We performed the surgery under spinal anesthesia. The surgery was uneventful and the baby was in a good health. After 9 hours of surgery, she complained of painless swelling in the parotid glands. Physical examination and laboratories were normal. We started rehydration with normal saline and one dose of hydrocortisone (100 mg IV route). Close monitoring showed no problems in swallowing or any purulent discharge. Two days later, we had a complete resolution of the swelling. We discharged the woman with her child with no complaints. Our case is one of the rare cases of anesthesia mumps after spinal anesthesia. Physicians should be careful in considering such rare cases. Early diagnosis and management is the key.
