In a 8 year-old boy who had epidural hematoma in the occipital area, had an episode of dislodgement of the endotracheal tube due to improper position. After operation, there were drowsy consciousness, irregular respiration, apnea, absence of cough reflex and swallowing reflex. Then these was no improvement in spite of treatment, and because of this hypoxic encephalopathy was diagnosed. WE suspected there might be some pathologic lesion volving the respiratory center and lower cranial nerves. CT scanning was performed and the result was diagnosed with epidural hematoma and subdural hematoma in the posterior fossa. The patient was reoperated.
