A female infant was born at 36 weeks with vacuum extraction. Her weight was 2.216 g and Apgar score was 9. She had a cephalohematoma at right parietal region. The cephalohematoma grew during 6 days after birth, then she came to our hospital. On arrival, her consciousness was alert and there were no neurological deficits. Her head circumference was 22.5 cm, and she had a pulsatile soft cephalohematoma, 7 cm in diameter, at right parietal region. Ultrasound examination showed a midline shift of the brain and CT scan revealed an epidural hematoma with bone fracture and cephalohematoma. We chose the puncture and continuous drainage of cephalohematoma as a primary therapy, because cephalohematoma was considered to be liquified and to be continuous to the epidural hematoma. The reason was that the pulsatile cephalohematoma became harder when she cried. The epidural hematoma was completely reduced on the next day's CT and then drainage was removed. She discharged on 15th post-operative day. We conclude that the puncture and continuous drainage of cephalohematoma may be one of the good therapeutic methods for the mild symptomatic neonate who has epidural hematoma with the cephalohematoma and bone fracture.
