Clinical Trigonometry: Right Hepatic Trisegmentectomy After Radiation Trisegmentectomy for Hepatocellular Carcinoma

A 73-year-old man with a history of hepatitis B infection was noted on annual screening abdominal ultrasound to have a new mass in the right hepatic lobe. At the time, he reported a 10-lb weight loss and intermittent abdominal pain over 2 months. Computed tomography (CT) of the abdomen and pelvis revealed a 6.2-cm hypervascular mass in the right hepatic lobe with washout in the venous phase, consistent with hepatocellular carcinoma. Tumor thrombus into the anterior branch of the right portal vein was noted. There was no evidence of distant metastasis.
