Blake pouch remnant, also known as Blake pouch cyst or persistent Blake pouch, is a posterior fossa embryologic anomaly that is often seen in isolation with most affected patients being asymptomatic. However, even in isolation, Blake pouch remnant can result in obstructive hydrocephalus requiring early neurosurgical intervention making it an important diagnosis for the fetal radiologist to consider. We present a rare case of a patient with prenatally diagnosed "inferior vermian hypoplasia" on fetal MRI that went on to develop progressive obstructive hydrocephalus in infancy secondary to what was determined to be a Blake pouch remnant.
布雷克囊残余物，也称为布雷克囊囊肿或持续性布雷克囊，是一种后颅窝胚胎学异常，通常单独出现，大多数受影响的患者无症状。然而，即使是单独出现，布雷克囊残余物也可能导致梗阻性脑积水，需要早期神经外科干预，这使其成为胎儿放射科医生需要考虑的重要诊断。我们报告了一例罕见病例，该患者在胎儿磁共振成像（MRI）上产前被诊断为“下蚓部发育不全”，婴儿期因确定为布雷克囊残余物而继发进行性梗阻性脑积水。
