This paper presents four posterior, interhemispheric cerebral cysts found at perinatal autopsy. All cysts appeared to attenuate the overlying posterior corpus callosum. All had a base over the roof of the third ventricle and midbrain with a lining that resembled tela choroidea with the choroid plexus tufts projecting into the lumen of the cyst. Three cases had enlargement of the lateral ventricles. One case had complete communication between the cyst and the posterior lateral ventricles reminiscent of a holoprosencephaly confined to the posterior telencephalon. One case demonstrated a complete VATER association and two others had some features of the VATER association. We hypothesize that this latter relationship suggests an origin for the cysts during blastogenesis.
本文介绍了在围产期尸检中发现的四个半球间脑后部囊肿。所有囊肿似乎都使上方的胼胝体后部变薄。所有囊肿都以第三脑室顶部和中脑为基底，其内膜类似于脉络丛组织，脉络丛绒毛突入囊肿腔内。三例伴有侧脑室扩大。一例囊肿与后外侧脑室完全相通，类似局限于后脑的前脑无裂畸形。一例表现为完全的VATER联合征，另外两例有VATER联合征的一些特征。我们推测，后一种关系提示囊肿在胚胎发育早期形成。
