A 68-year-old woman with hepatocellular carcinoma underwent a liver transplant. On preoperative evaluation, she had an α1-fetoprotein level of 43.7 ng/mL (normal range, <8 ng/mL [to convert to micrograms per liter, multiply by 1.0]), and a computed tomographic scan of her chest and a bone scan both had negative results. Her tumor was within the Milan criteria. Her native liver explant revealed a T2 lesion without vascular invasion or lymph nodes positive for tumor. One month later, she underwent a retransplant owing to hepatic artery disruption. The liver pathology only showed ischemia. The patient had a satisfactory recovery.

She presented to the emergency department a year later complaining of nausea, vomiting, and weight loss (6.3 kg [14 lb]). On physical examination, she was anicteric, afebrile, and normotensive with no hepatomegaly. Her workup included a white blood cell count of 3800/μL (normal range, 4-11/μL [to convert to ×109 per liter, multiply by 0.001]), a hemoglobin level of 7.6 g/dL (normal range, 12-16 g/dL [to convert to grams per liter, multiply by 10.0]), a creatinine level of 1.3 mg/dL (normal range, 0.7-1.5 mg/dL [to convert to micromoles per liter, multiply by 88.4]), normal albumin and liver enzyme levels, and a normal coagulation profile. Imaging studies included magnetic resonance imaging of the abdomen, computed tomographic angiography, a chest computed tomographic scan, a bone scan, and ultrasonography, all of which had negative results. She subsequently underwent a positron emission tomographic/computed tomographic scan (Figure).
