Ganglionic eminence (GE) is the main proliferative structure of the ventral
telencephalon and contributes to GABA-ergic cortical interneuron population; GE
imaging characterization in normal and abnormal conditions is poor. After
searching a 3500 cases fetal MR database, we illustrate normal GE features, its
abnormalities and its possible associations. GE malformations are divided: 1)
bilateral symmetric cavitations as inverted C shape separating GE from
parenchyma; 2) GE volume increase associated or not with the above mentioned
cavitation. About half of cases are associated with micro-lissencephaly, the
others with minor-moderate anomalies. As group apart are presented clastic GE
lesions, featuring haemorrhagic changes.
