Resection of a Large Hepatocellular Carcinoma Located in the Dorsocaval Spiegel Lobe at the Origin of the Inferior Vena Cava Ligament —A Case Report—

Abstract

A 72-year-old woman was referred to our hospital for the treatment of hepatocellular carcinoma detected by screening. Abdominal dynamic computed tomography showed a hepatocellular carcinoma, 60 mm in diameter, located in the S1 Spiegel lobe of the liver in the vicinity of the inferior vena cava ligament, compressing the vena cava from the dorsal side. She had good liver functional reserve and underwent Spiegel lobectomy with left hemi-hepatectomy using the anterior transhepatic approach. Pathologically, the tumor was a simple nodular type of moderately differentiated hepatocellular carcinoma without vascular invasion, with a resection margin of 0 mm without tumor exposure. Two years and one month after the operation, she is alive without recurrence. A rare case of hepatocellular carcinoma on the dorsal side of the inferior vena cava is reported.
