Are liver hemangiomas common?

Hepatic hemangiomas can occur multifocally, but this is not the case for most patients. Clinically, solitary hepatic hemangioma is more common. When multiple lesions are present, they typically involve 2–3 foci, and most cases are asymptomatic, often discovered incidentally during routine physical examinations. These usually do not significantly affect liver function. However, if any of the multiple hemangiomas exceed 5 cm in diameter or are accompanied by abdominal pain, prompt medical evaluation is recommended.

Clinical data indicate that 20%–30% of patients with hepatic hemangiomas have multiple lesions, which are distributed across different regions of the liver and may vary in size—some small lesions measure only a few millimeters in diameter, while larger ones can reach several centimeters. These multiple hemangiomas are mostly benign, grow slowly, do not undergo malignant transformation, and rarely pose risks such as rupture or hemorrhage.

The development of multiple hepatic hemangiomas may be associated with congenital vascular abnormalities, hormonal fluctuations, and other factors. Female patients have a slightly higher likelihood of developing multiple hemangiomas due to hormonal influences. In most cases, no specific treatment is required for multiple hemangiomas; regular ultrasound monitoring of lesion size is sufficient. If there is no significant growth, long-term follow-up observation is appropriate, and excessive concern is unnecessary.

In daily life, it is important to maintain a regular作息 (routine), avoid chronic sleep deprivation to reduce liver strain, limit alcohol consumption, follow a light and balanced diet, avoid excessive intake of high-fat foods, and adhere to scheduled follow-up examinations to stay informed about changes in the number and size of hepatic hemangiomas.
