| ABSTRACT |
|
Most of the liver masses that are incidentally found are benign lesions. Focal nodular hyperplasia (FNH) is the second most common benign solid hepatic mass that does not transform to malignancy. A 43-year-old woman who was diagnosed with breast cancer recently visited our clinic for evaluating an incidentally found hepatic mass. Abdomen computed tomography and magnetic resonance imaging showed two lesions on segment 6 of the liver suggestive of FNH. She underwent surgery for breast cancer and started to take tamoxifen. We followed lesions with abdomen ultrasound every six months. Imaging studies at two years after diagnosis revealed fatty change of liver parenchyma and increase of size and number of previous masses. Liver biopsy was performed to distinguish metastatic lesions. Conclusively, FNH with drug-induced steato-hepatitis was confirmed by histopathologic finding. We are following up the patient with imaging study and liver fibroscan. |
