Management of Hepatic Hemangioma

Overview and Diagnosis

Hepatic hemangiomas are the most common benign liver tumors with a prevalence ranging from 0.4% to 7.3%, with a female-to-male ratio of up to 5:1 1, 2
Diagnosis is typically established through imaging techniques including ultrasound, CT, or MRI, with characteristic findings of peripheral nodular enhancement in the arterial phase and complete or incomplete centripetal filling in the portal venous and late phases 3
CEUS (contrast-enhanced ultrasound) can be useful for diagnosis, showing peripheral nodular enhancement and centripetal filling, though it has limitations for tumor staging 3, 4

No specific treatment is indicated for asymptomatic hemangiomas regardless of size, according to the American Association for the Study of Liver Diseases 5
For hemangiomas >10 cm, the risk of rupture increases to approximately 5%, particularly in peripherally located and exophytic lesions, as reported by the European Association for the Study of the Liver 1, 2
Discussion about potential treatment may be considered for giant hemangiomas >10 cm, especially if planning pregnancy, as recommended by the American College of Gastroenterology 1, 2

Pregnancy is not contraindicated in women with hepatic hemangiomas, even giant ones, according to the American College of Obstetricians and Gynecologists 1, 2
Hemangiomas may increase in size during pregnancy, but most pregnancies in individuals with hemangiomas do not develop complications, as stated by the Society for Maternal-Fetal Medicine 1, 2
For giant hemangiomas (>10 cm), discussion about treatment prior to conception should be considered due to slightly increased risk of complications, as suggested by the American Society for Reproductive Medicine 1, 2
Close monitoring with ultrasound is recommended during pregnancy for women with giant hemangiomas, according to the International Society of Ultrasound in Obstetrics and Gynecology 1, 6
Pediatric hepatic hemangiomas require special consideration as they may be associated with high-output cardiac failure in rare cases, as reported by the American Academy of Pediatrics 7
Diffuse hepatic hemangiomas in infants can lead to severe complications including hepatomegaly and hypothyroidism, as stated by the Pediatric Endocrine Society 7
