What’s your diagnosis in this second trimester pregnancy?

This image shows a small occipital cystic lesion confined to the scalp. There is no involvement of the intracranial (brain) tissue and no abnormality of the ventricular system. In addition, the occipital bone does not show any defects. These findings point to a scalp cyst rather than an occipital meningocele or encephalocele.
