This second portion of a two-part review illustrates examples of posterior fossa disorders detectable on prenatal ultrasound and MRI, with postnatal or pathology correlation where available. These disorders are discussed in the context of an anatomic classification scheme described in Part 1 of this posterior fossa anomaly review. Assessment of the size and formation of the cerebellar hemispheres and vermis is critical. Diagnoses discussed here include arachnoid cyst, Blake's pouch cyst, Dandy-Walker malformation, vermian agenesis, Joubert syndrome, rhombencephalosynapsis, Chiari II malformation, ischemia, and tumors.
这篇分为两部分的综述的第二部分展示了可在产前超声和磁共振成像（MRI）中检测到的后颅窝疾病实例，并在可行的情况下与产后情况或病理结果进行了相关性分析。这些疾病是在本后颅窝异常综述第一部分所描述的解剖学分类方案的背景下进行讨论的。评估小脑半球和蚓部的大小及形成情况至关重要。这里讨论的诊断包括蛛网膜囊肿、 Blake 囊肿、 Dandy-Walker 畸形、蚓部发育不全、 Joubert 综合征、 rhombencephalosynapsis、 Chiari II 畸形、缺血和肿瘤。
