Hepatic Hemangioma: Pathogenesis, Presentation, Imaging, and Management

Hepatic hemangiomas are the most common benign liver lesion, occurring in 5% to 20% of the population.
Hemangiomas are congenital malformations comprising blood-filled cavernous spaces lined by a single layer of endothelial cells and separated by fibrous tissue.
Hemangiomas are well-encapsulated and have no potential for malignant transformation.
Most patients present with a single lesion, though up to 10% of patients may present with multifocal disease throughout the liver.
Hemangiomas are small, ranging from several millimeters to several centimeters in diameter, although in rare cases lesions may be greater than 10 cm, which are referred to as giant hemangiomas.
Hemangiomas are rarely symptomatic, and the majority of cases are incidentally diagnosed during abdominal imaging for other indications.
Imaging modalities such as ultrasound, CT, and MRI can be used to diagnose hemangiomas based on characteristic appearance.
Indications for surgical resection include significant growth, significant symptoms that are unresponsive to analgesics and interfere with daily living, or, in exceedingly rare cases, rupture and hemorrhage.
Unexplained abdominal pains are common in patients with hemangiomas, and it is important to carefully exclude other causes of abdominal pain before ascribing the pain to a known hemangioma.
Resection can be completed by either open or minimally invasive approaches and involves tumor enucleation, wedge resection, or a formal segmental resection based on the size and location of the lesion in proximity to major biliary and vascular structures.
For large hemangiomas, preoperative hepatic arterial embolization has been used to mitigate intraoperative bleeding, though this is rarely necessary.
Orthotopic liver transplant has been used for large, unresectable lesions with good success, but there are currently no effective medical therapies for hemangiomas.
