Eleven infants were encountered (nine premature, two term) in whom well-defined small periventricular cavitations were found by sonography in the first week of life. The sonographic findings bore remarkable similarity to subependymal pseudocysts in neonates previously described in autopsy specimens. The cavitations, which were identified predominantly along the superolateral aspects of the lateral ventricles, did not evolve in the manner of postnatally acquired periventricular leukomalacia. The location of the cavitations differed from the site of previously reported lesions of posthemorrhagic and postinfectious germinolysis along the medial aspect of the caudothalamic groove. Neurosonologists and neonatologists should be alerted to this finding and encouraged to follow these infants as a separate group to learn whether neurodevelopmental sequelae occur in these children.
在11例婴儿（9例早产儿，2例足月儿）中，在出生后第一周通过超声检查发现了界限清晰的小室周空洞。超声检查结果与先前尸检标本中描述的新生儿室管膜下假性囊肿有显著相似性。这些空洞主要沿侧脑室的上外侧缘发现，其演变方式不同于出生后获得性脑室周围白质软化。空洞的位置与先前报道的出血后和感染后尾状丘脑沟内侧的生殖层溶解病变部位不同。神经超声学家和新生儿科医生应注意这一发现，并鼓励将这些婴儿作为一个单独的群体进行随访，以了解这些儿童是否会出现神经发育后遗症。
