Ultrasonography in the diagnosis of fetal abnormalities is well documented, and improvements in technology have made possible detailed visualization of the intracranial anatomy. Ten per cent of major fetal abnormalities involve the head and neck. A case of simulation of a posterior fossa cyst by normal, hypoechoic white matter on cranial ultrasonography is presented. Potential pitfalls and the differential diagnosis of intracranial abnormalities in utero are discussed.
超声检查在胎儿异常诊断中的应用已有充分记录，技术的进步使颅内解剖结构的详细可视化成为可能。10%的主要胎儿异常涉及头颈部。本文介绍了一例在头颅超声检查中正常的低回声白质模拟后颅窝囊肿的病例。并讨论了宫内颅内异常的潜在陷阱及鉴别诊断。
