[Three cases of acute subdural hematoma in abused children].

We encountered 3 cases of battered children with acute subdural hematoma. In this report, we discuss the difficulties in treating this condition surgically, and we emphasize the importance of early diagnosis and treatment of abused children and their parents. Case 1: A girl, aged 2 months, was brought in by her mother, because the child had become drowsy. The mother stated that the child had been battered by her father. Physical examination revealed tense anterior fontanelle, bruises on her face, consciousness disturbance and retinal bleeding. Marked anemia was revealed on laboratory studies. A computed tomographic (CT) scan demonstrated an interhemispheric subdural hematoma in the parietooccipital region. She was treated conservatively for 2 months. Follow-up CT revealed a bilateral chronic subdural hematoma. Burr hole irrigation and drainage on both sides brought about complete disappearance of these lesions. Case 2: A girl, aged 1 year and 9 months, was brought in by her parents. According to her mother's allegation, the child fell down from the top of an indoor slide and became comatose. Physical examination revealed severe malnutrition, loss of consciousness, dilated pupils and negative light reflex. Numerous areas of subcutaneous bleeding and skin erosions were seen on her back and abdomen. Marked anemia was revealed on laboratory studies. CT scan demonstrated a left acute subdural hematoma and massive brain swelling. Despite an emergency craniotomy, the child died 5 days later. Case 3: A 4-year-old boy was admitted in a comatose state. According to his mother's allegation, he was thrown to the floor from a 1.5m height and struck against a wall by his father. Physical examination revealed severe malnutrition, consciousness loss, dilated pupils and negative light reflex. Many scratches and bruises were seen over his whole body, especially on his back. Marked anemia was revealed on laboratory studies. A CT scan demonstrated a left acute subdural hematoma and massive brain swelling. Three days later, he died despite emergency craniotomy. The incidence of battered children is increasing in Japan, and these cases sometimes involve severe head injuries, such as subdural hematoma. In these cases, successful surgical treatment is difficult after admission to the neurosurgical institute. This may result from late admission as well as marked anemia and malnutrition. Therefore, we conclude that early diagnosis of child abuse and treatment of the abused child and psychological treatment for their parents are very important.
