Despite the immature state of the fetal brain at this early stage, early suggestive signs of the presence of brain malformations can be recognized. To differentiate between the normal dynamics of the growing brain and the developing pathological conditions can be challenging and requires extensive knowledge of normal central nervous system developmental stages and their neuroradiological counterparts at those different stages. This article reviews the second\u2010trimester appearances of some commonly encountered brain malformations, focusing on helpful tricks and subtle signs to aid in the diagnosis of such conditions as rhombencephalosynapsis, various causes of vermian rotation, molar tooth spectrum anomalies, diencephalic\u2010mesencephalic junction dysplasia, ganglionic eminence anomalies, and the most common malformations of cortical development.<\/jats:p>","DOI":"10.1002\/jcu.23423","type":"journal-article","created":{"date-parts":[[2023,2,14]],"date-time":"2023-02-14T06:19:30Z","timestamp":1676355570000},"page":"283-299","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Second
