In the fetal liver, which lobe is commonly larger?

Explanation:
In the fetus, the left lobe of the liver tends to be larger than the right. This happens because the liver grows rapidly to fill the left side of the upper abdomen as development proceeds, and the left lobe expands to occupy the available space beneath the developing diaphragm. The right lobe remains comparatively smaller early on, so the left lobe becomes the more prominent portion on prenatal imaging. This pattern is a normal variant in fetal anatomy.
