In this report we describe two cases of fetal midline intracranial cyst presenting with ventriculomegaly at routine detailed second‐trimester scan. In the first case, additional findings included a banana‐shaped hypoplastic cerebellum and macrocephaly; autopsy after termination of the pregnancy revealed a glioependymal cyst. In the second case, subsequent follow‐up examination revealed a progressive increase in cyst size and worsening of ventriculomegaly; termination of pregnancy was performed at 24 weeks and autopsy confirmed an arachnoid cyst. These cases document interhemispheric cyst as a cause for early ventriculomegaly in utero .
