Hepatic adenoma in pregnancy: A novel arterial embolization of hepatic adenoma in a pregnant patient

A 31-year-old Caucasian female presented to the emergency department where a CT revealed a large right lobe liver mass found to be a hepatic adenoma. The patient ceased taking her oral contraceptives, but subsequently became pregnant. Serial ultrasounds revealed the adenoma was enlarging steadily throughout pregnancy, and the patient underwent a hepatic adenoma trans-arterial embolization at 33 weeks gestation to reduce the risk of bleeding in the third trimester and during labor. Embolization for treatment of a hepatic adenoma in a patient who is pregnant is a relatively novel approach to reducing the tumor size and reducing the bleeding risk associated with the third trimester of pregnancy. The patient had no postprocedure complications, and postprocedure imaging revealed the hepatic adenoma decreased in size with no further intervention required to date.
