Progressive enlargement of an hepatic cell adenoma.

Over a 5-mo period, an hepatic cell adenoma was noted to increase considerably in size, despite discontinuation of oral contraceptives. Progressive tumor enlargement was documented by hepatic angiography, computed tomographic scan (CT scan) of the liver and 99mTc liver scan. The repeat hepatic angiogram also revealed that the tumor had become more vascular. Multiple adenomas were in fact seen by all three techniques mentioned above. At surgery, seven hepatic cell adenomas were demonstrated, of which four were resected.
