BACKGROUND
Perinatal infratentorial haemorrhage (PIH) is a rare birth complication associated with abnormal labour.
CASE PRESENTATION
A baby boy was born by vacuum extraction at 41 weeks' gestational age. The pregnancy was uneventful and Apgar scores were 3/6/9. Following initial resuscitation, insufficient and irregular breathing, non-reactive pupils and absence of spontaneous movements were noted. A diagnosis of perinatal asphyxia with hypoxic-ischaemic encephalopathy (HIE) was considered. Therapeutic hypothermia (TH) for 72 hours was initiated. Cerebral ultrasound showed only a mildly hyperechogenic periventricular substance. A brain MRI on the fourth day of life revealed a subdural haemorrhage in the posterior fossa with compression of the fourth ventricle.
CONCLUSION
PIH is an important differential diagnosis to HIE that can be missed with ultrasound. PIH is a treatable condition but may be aggravated by TH. Therefore, in neonates at risk for PIH, a more detailed ultrasound protocol or brain MRI should be considered early.
背景
围生期幕下出血（PIH）是一种与异常分娩相关的罕见出生并发症。
病例报告
一名男婴在孕41周时通过真空吸引分娩。孕期无异常，阿氏评分分别为3/6/9。初始复苏后，发现呼吸不足且不规律、瞳孔无反应以及无自主运动。考虑诊断为围生期窒息合并缺氧缺血性脑病（HIE）。开始进行72小时的治疗性低温（TH）。脑部超声仅显示脑室周围物质轻度回声增强。出生第四天的脑部MRI显示后颅窝硬膜下出血并压迫第四脑室。
结论
PIH是HIE的重要鉴别诊断，超声检查可能会漏诊。PIH是一种可治疗的疾病，但TH可能会使其加重。因此，对于有PIH风险的新生儿，应尽早考虑采用更详细的超声检查方案或脑部MRI。
