First, you need to confirm the liver lesions are hemangiomas with CT and/or MRI. If they are hemangiomas, then those are benign.
I did find some info from mayo clinic . Org
It's not clear what causes a liver hemangioma to form. Doctors believe liver hemangioma is congenital — meaning that you're born with it.
Liver hemangioma usually occurs as a single abnormal collection of blood vessels that is less than about 1.5 inches (about 4 centimeters) wide. Occasionally liver hemangiomas can be larger or occur in multiples.
In most people, liver hemangioma will never grow and never cause any signs and symptoms. But in a small number of people, liver hemangioma will grow to cause complications and require treatment. It's not clear why this happens.
I would think the best person to answer your question would be your doctor. They have all your data and the knowledge to go along with it to interprete your results. We would only be wild blue sky guessing at best.
Good luck and please let us know what your find out
