Introduction
In general, whether hepatic hemangiomas are congenital depends on the specific case. Some hepatic hemangiomas are caused by congenital factors and are either present at birth or remain latent; others arise from acquired factors and gradually develop in adulthood. In daily care, regular imaging examinations are needed to monitor changes in the size of hepatic hemangiomas, and behaviors that may damage the liver—such as alcohol consumption and staying up late—should be avoided.
In general, whether hepatic hemangiomas are congenital depends on the specific circumstances. Some hepatic hemangiomas are caused by congenital factors and may either be present at birth or remain dormant; others arise from acquired factors and gradually develop in adulthood. The detailed analysis is as follows:
If a hepatic hemangioma is related to congenital factors, it usually results from abnormal proliferation of vascular endothelial cells during embryonic development, leading to structurally abnormal blood vessels. Such hemangiomas may already exist at birth but remain undetected due to their small size, becoming noticeable only with age. They typically grow slowly and do not significantly affect health.
If a hepatic hemangioma arises from acquired factors, common triggers include hormonal changes and localized liver vessel injury. These factors can stimulate endothelial cell proliferation, eventually forming a hemangioma. These types usually appear in adulthood and may slowly enlarge as long as the triggering factors persist.
In daily care, regular imaging examinations should be conducted to monitor changes in the size of hepatic hemangiomas. Behaviors that damage the liver—such as alcohol consumption and staying up late—should be avoided. Maintaining a regular lifestyle and healthy diet is also recommended.
