Overview
Hepatic hemangioma natural history
- Hepatic hemangioma is the most common benign liver tumor and typically remains stable in size.[1]
- These are usually diagnosed as asymptomatic incidental findings.
- Hemangiomas also (rarely) rupture spontaneously or by trauma and then lead to acute hemorrhagic shock with upper abdominal pain.[2][3]
- In the worldwide literature a total of only 97 cases with a rupture of a hemangioma have been published, whereas a spontaneous rupture only happened in 47.4% of cases.[4][3]
- Further investigation showed that these spontaneously ruptured hemangiomas had a mean size of 11.2 cm.[3][4]
- Despite therapy, in these situations the mortality rate is 30-40%.[3]
- Hemangiomas generally have no growth tendency. In the literature, however, cases of hemangioma growth during pregnancy or after estrogen administration are described [1, 10]. Hemangiomas (10 cm should generally not be treated, even before a pregnancy. In case of a planned pregnancy and a size )10 cm, due to the risk of a possible rupture, a definitive treatment should be discussed [1, 10]. Several studies have concluded that a spontaneous rupture of a hemangioma (even while pregnancy) [10, 19] occurs only very rarely, and therefore a prophylactic resection should only be conducted under special conditions and especially with a size of the hemangioma >11 cm [10]. In case of hemangiomas with high growth trend (>3 cm in 12 months), with symptomatic compression symptoms or recurrent pain, which may correlate with hemorrhage into the lesion, surgical intervention should be indicated [18, 19]. Because of hypotension, unexplained anemia, or diagnosis difficulties of the liver lesion, surgical intervention can be rarely necessary.[3]
Complications
In rare cases, a cavernous hemangioma may rupture. Babies may develop a type of hepatic hemangioma called benign infantile hemangioendothelioma (also called multinodular hepatic hemangiomatosis). This rare, noncancerous tumor has been linked to high rates of heart failure and death in infants. Infants are usually diagnosed by the time they are 6 months old. Pregnancy and estrogen-based medications can cause cavernous hemangiomas to grow.
