Abstract
BackgroundAgenesis of the left hepatic lobe is a rare anomaly. It is defined as the absence of liver tissue to the left of the gallbladder fossa. Additionally, agenesis of the left hepatic lobe accompanied by hepatocellular carcinoma is quite rare. We experienced the case of a patient with agenesis of the left hepatic lobe, undergoing laparoscopic hepatectomy for HCC.Case presentationA 79-year-old man was referred to our department with epigastralgia. Abdominal computed tomography revealed agenesis of the left hepatic lobe, accompanied by hepatocellular carcinoma in segments 7 and 8. He underwent laparoscopic partial hepatectomy of segments 7 and 8. The operative findings revealed complete agenesis of the liver to the left of the falciform ligament. The patient had a favorable clinical course without liver dysfunction or any complications.ConclusionsWe experienced a case with agenesis of the left hepatic lobe undergoing laparoscopic hepatectomy for HCC. Awareness of such anomaly is important for surgeons to avoid postoperative complications.

Summary
Agenesis of a hepatic lobe is defined as the absence of liver tissue to the right or left of the gallbladder fossa [1]. Because agenesis of a hepatic lobe is clinically asymptomatic, it is usually an incidental finding, revealed by imaging examinations [4]. We report the case of a patient with agenesis of the left hepatic lobe, who underwent laparoscopic hepatectomy for hepatocellular carcinoma (HCC). Computed tomography (CT) findings revealed the absence of the left lobe of the liver (Fig. 1c). Based on the radiological findings, our preoperative diagnosis was HCC in S7 and S8, accompanied with agenesis of the left hepatic lobe. Intraoperative findings showed absence of the left lobe of the liver (Fig. 4a). There was complete agenesis of the liver to the left of the falciform ligament (Fig. 4c) These findings confirmed the diagnosis of congenital agenesis of the left hepatic lobe. The patient had a favorable clinical course without liver dysfunction or any complications, and he was discharged on postoperative day 11
