In brief: Trauma growth
By far most liver hemangioms do not cause any issues at all some are large and like any big complex of blood vessels a traumatic injury like car accident boxing or even skate board fall can break it open or rupture.
... Also very rarely they will continue to grow and eventually rupture....These growing hemangiomas become cavernous and may require surgery to prevent unwanted rupture.
