title: Disappearance of liver cell adenoma: CT and MR imaging.
abstract: We report the disappearance of liver cell adenoma, documented by computed tomography (CT) and magnetic resonance (MR) imaging. A 42-year-old woman with a diagnosis of hepatic adenoma was followed up by CT and MR imaging after cessation of oral contraceptive use. At the time of diagnosis, the adenoma was 4 cm in diameter and appeared hypervascular on CT. At MR imaging, the lesion was hypointense on T1-weighted sequences, and hyperintense on T2-weighted sequences. The lesion disappeared 4 years after cessation of oral contraceptive use. We conclude that in nonoperated patients CT scans and MR imaging are useful for following the evolution, and documenting the regression, of liver cell adenomas.
