THE INCIDENCE of ectopic pregnancy ranges from one in 84 to one in 357 live births.1 The most common site of implantation is within the fallopian tubes; abdominal pregnancies are unusual, and primary hepatic pregnancies are extremely rare. A computer search revealed only six cases2-7 of placental attachment to the liver in the English-language literature since Cornell and Lash8 reported eight cases in 1933. The presence of a fetus has been described in only two of these cases6,7; either chorionic villi or trophoblasts have been documented in the remaining reports. While preoperative angiography was described in one case,3 newer imaging techniques such as ultrasonography, computed tomography (CT), and imaging with magnetic resonance (MR) have not been used in the diagnosis and evaluation of hepatic pregnancy. These techniques have a greater ability to define tissue planes, thus allowing more accurate diagnosis and preoperative planning by the
