Only a few traumatic cerebellar hematomas have been reported. Two young patients who had traumatic cerebellar hematomas with different outcomes are reported. Case 1 was an 11-year-old schoolboy who was hit in the occiput by his friend's fist. He complained of headache, nausea, and vomiting for 3 days after the head injury. A computed tomography (CT) scan revealed a walnutsized hematoma in the left cerebellar hemisphere and vermis. After observation for about a month, he was discharged without neurological signs. Case 2 was a 9-year-old schoolgirl who was struck in the occiput in a traffic accident. On admission, she was alert and no neurological findings were observed. A craniogram showed a linear fracture in the left occiput, but the CT was not remarkable. Her consciousness level abruptly deteriorated 4 hours after the accident. CT revealed a walnut-sized hematoma involving the left cerebellar hemisphere and vermis. The hematoma was completely removed by an emergency operation. However, she expired 19 hours after the accident with atrioventricular block. Traumatic cerebellar hematoma can be roughly divided into two groups. One is a slowly enlarging hematoma with good prognosis, and the other is a rapidly growing hematoma with poor prognosis.
