Hepatocellular adenoma is a rare, benign hepatic tumor, possibly associated with such factors as glycogen storage disease and long-term intake of oral contraceptives. The first of the two cases reported here was that of a 31-year-old woman who had used oral contraceptives for several months at the age of twenty-one. Case 2 was that of a 44-year-old man with no history of glycogen storage disease or use of steroids. Gray-scale US showed an isoechoic tumor about 7 cm in diameter in the left hepatic lobe in case 1 and a hypoechoic tumor about 8 cm in diameter in the left hepatic lobe in case 2. Color Doppler US showed multiple blood blow signals in the peripheral and central portions of these two tumors. Pulsed Doppler imaging showed a pulsatile waveform in the peripheral portion and a continuous waveform in the central portion of both tumors. Although sonographic criteria for diagnosing hepatocellular adenoma have not yet been established, Doppler US may prove useful in the diagnosis of hepatocellular adenoma.
