Hepatic hemangioma: What internists need to know

Area of Science:

• Hepatology
• Vascular Malformations
• Oncology

Background:

• Hepatic hemangioma (HH) is the most frequent benign liver neoplasm, typically discovered incidentally.
• Its exact pathophysiology remains unclear, though it originates from vascular malformations.
• Symptoms and complications are often related to tumor size and location.

Purpose of the Study:

• To review the diagnosis and management of hepatic hemangioma.
• To differentiate between observation and active treatment strategies.
• To discuss surgical and non-surgical treatment outcomes.

Main Methods:

• Review of diagnostic imaging hallmarks for HH.
• Analysis of treatment guidelines for asymptomatic and symptomatic HH.
• Comparison of surgical (enucleation, hepatectomy) and non-surgical (embolization, ablation) modalities.

Main Results:

• Diagnosis is primarily based on characteristic imaging findings.
• Observation is standard for asymptomatic HH, with follow-up for lesions >5 cm.
• Symptomatic HH management includes surgery or non-surgical options; enucleation offers better outcomes.

Conclusions:

• Clinical presentation dictates management, balancing observation with intervention.
• Enucleation is a preferred surgical approach for symptomatic HH due to lower complication rates.
• Hormonal influence on HH growth is suspected but lacks definitive evidence for contraindicating hormonal therapy.
