MRI of the liver with contrast showing a sizable hemorrhagic HA measuring 9.0 x 8.5 cm and adjacent nonhemorrhagic HA 5.9 x 5.1 cm (segment 4) and several HAs smaller than 5 cm in diameter.

Another one was a nonhemorrhagic lesion 5.9 x 5.1 cm, inseparable from the dominant mass (Figure 1).
(a) Subselective catheterization of the hepatic artery, segment 8 branch with arteriography. (b) Cone beam CT demonstrating patency and perfusion of the hepatic adenoma. (c) Coil embolization of segment 8 branch of the hepatic artery.

The emergent transarterial embolization of the lesion was performed, considering rapid expansion and life-threatening hemorrhage risk (Figure 2).
CT scan of the abdomen performed the next day after embolization showing the decrease in the dominant lesion size to 8.0 x 7.9 cm.

The CT scan completed the next day showed a decrease of adenoma to 8.0 cm x 7.9 cm (Figure 3) along with the increase in hemoglobin levels, confirming the successful embolization.
CT scan of the abdomen repeated in two months showing that the dominant HA decreased in size, measuring 7.1 x 5.7 cm, with coils and a resolved hemorrhagic component. The nonhemorrhagic mass in segment four decreased to 4.2 cm in diameter.

It showed a decrease in the size of the dominant lesion with a complete resolution of the hemorrhagic component (Figure 4).
