A woman in her 40s was referred to our service owing to unusual findings detected on routine abdominal ultrasonography ordered by her gynecologist. The ultrasonographic scan showed a hepatic mass in the right lobe composing approximately 50% of the liver parenchyma. The patient was asymptomatic, and there were no significant findings on abdominal physical examination— the liver was not palpable. Results of whole blood analyses, including α-fetoprotein, were within the reference ranges. She had not received any medication, including contraceptive pills or hormones, for more than 10 years.
