Q: I had a level 2 sonogram at 20 4/7 weeks. The results of the sonogram are - No evidence of fetal anomalies. However, shape of fetal head is Dolichocephalic. What does that mean? I understand that it is related to the head measurements. Is it a cause of concern?

A:Dolicocephaly refers to a head shape that is longer than wide. Most of the time this is a normal variant and a follow-up scan would confirm this. Occasionally this is a sign of a generalised disorder of organ formation and this would be more evident in the follow-up scan. Once that is clear there is no cause for worry.
