We describe the finding of cavum veli interpositi (CVI) on fetal ultrasound and MRI and the postnatal MRI and developmental follow-up in two cases. The first case was diagnosed on fetal ultrasound at 33 weeks' gestation and confirmed on fetal MRI. No abnormalities were detected on postnatal examinations and the brain MRI at 1 year of age showed no changes. At 4 years of age, his growth and development were normal.The second case was diagnosed with CVI on fetal ultrasound and MRI at 33.5 weeks' gestation. Postnatal examination showed no abnormalities, and brain MRI at 8 months of age revealed that the CVI was unchanged, but there was a dilated cavum septum pellucidum and cavum vergae. Her growth and development during the first 4 years of life were normal. CVI is a rare fetal ultrasound finding, which seems to be benign. However, further neurodevelopmental follow-up is needed to confirm this observation.
我们描述了两例胎儿超声和磁共振成像（MRI）检查发现中间帆腔（CVI），以及产后MRI检查和发育随访情况。第一例在孕33周时经胎儿超声诊断，并经胎儿MRI证实。产后检查未发现异常，1岁时脑部MRI显示无变化。4岁时，其生长发育正常。第二例在孕33.5周时经胎儿超声和MRI诊断为CVI。产后检查无异常，8个月时脑部MRI显示CVI无变化，但透明隔腔和穹窿腔扩张。其生命最初4年的生长发育正常。CVI是一种罕见的胎儿超声检查发现，似乎为良性。然而，需要进一步的神经发育随访以证实这一观察结果。
