Oral contraceptives and liver hemangioma: a case-control study.

Objective: To study whether there is an epidemiological association between liver hemangiomas and oral contraception use, as may be suggested by clinical observations of liver hemangioma growth during pregnancy and under estrogen administration.

Methods: A case-control study of 40 women with liver hemangiomas, as diagnosed by imaging studies [ultrasonography (US) or computed tomography (CT) and nuclear scan], and 109 age-matched control with normal studies. The women were interviewed with respect to their menstrual, reproductive and oral contraception use history.
