Abstract:
Gyration abnormalities often reflect severe neurological diseases. Their diagnosis is impeded by our limited knowledge about normal sulci anatomy throughout fetal brain development. Primary sulci appears in a specific chronology which is unchanged among all fetuses. We think it is interesting to remind of sulci anatomy and then to depict sulci MRI and ultrasonography appearance at 22, 27 and 32 weeks of gestation. We pay particular attention to the lateral sulcus, also called Sylvian fissure.
