We present a previously unreported association between the sonographic finding of an echogenic cavum septi pellucidi (CSP), concurrent hypointense signal within the CSP on fetal MRI and postnatal MR evidence of dysgenesis of the rostrum and genu of the corpus callosum as well as abnormal shortening of the septal leaflets. An echogenic or non-fluid filled CSP in the fetus at the midtrimester ultrasound is likely to represent a form of mild callosal dysgenesis. Perinatal assessment of vision and endocrine function and clinical follow-up of neurodevelopment and growth are probably indicated in such cases.
我们报告了一种此前未被报道的关联，即超声检查发现的透明隔腔（CSP）呈高回声，胎儿磁共振成像（MRI）显示CSP内同时出现低信号，以及产后磁共振成像（MR）证据表明胼胝体嘴部和膝部发育不全，同时隔叶异常缩短。孕中期超声检查发现胎儿CSP呈高回声或无液性填充，可能代表一种轻度胼胝体发育不全的形式。在此类病例中，可能需要进行围产期视力和内分泌功能评估以及神经发育和生长的临床随访。
