“…They concluded that even though the presence of an ectopic gallbladder and a distorted morphology of the liver due to compensatory hypertrophy of the left and caudate lobes may raise the suspicion of agenesis or hypoplasia of the right liver lobe, the main criteria for the diagnosis of aplasia should be the absence of right portal and right hepatic vein as well as a dilation of the left intrahepatic ducts. On the contrary, in cases of liver hypoplasia at least one of these venous structures is present (17). In our case, the CT of the abdomen showed the presence of a hypoplastic right hepatic vein, while no right portal vein was identified.…”

Agenesis or hypoplasia of the right hepatic lobe combined with a floating gallbladder is an extremely rare condition. We report a case of hypoplasia of the right hepatic lobe, discovered in a 65-year old female. This was an incidental finding at CT scan for staging of a right colonic cancer. The CT evidenced the presence of a hypoplastic right lobe, while the left lobe was diffusely enlarged. Furthermore, the gallbladder was described as floating with partially calcified walls. The diagnosis of this rare anomaly was confirmed intraoperatively. The patient underwent right hemicolectomy and cholecystectomy. Biopsies were taken from both right and left hepatic lobes, revealing the presence of normal hepatic parenchyma. Since all causes of acquired atrophy of the liver had been ruled out, we considered this case to be of congenital origin.

“…The incidence of hepatic lobe agenesis is very low [2, 3]. Because agenesis of a hepatic lobe is clinically asymptomatic, it is usually an incidental finding, revealed by imaging examinations [4].…”

Agenesis of the left hepatic lobe undergoing laparoscopic hepatectomy for hepatocellular carcinoma: a case report

et al. 2017

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.

“…Chou et al 6 reported eight cases of retrohepatic gallbladder, two associated with agenesis of the right hepatic lobe, and six associated with atrophy of right hepatic lobe, and they showed that the absence of visualization of all of the right hepatic vein, right portal vein and its branches, and dilated right intrahepatic ducts is a prerequisite of the diagnosis of agenesis of the right hepatic lobe. Naganuma et al 7 observed 18 patients with gallbladder anomalous position and tried to determine its ultrasound findings in order to avoid misdiagnosis: Nine patients presented left‐side gallbladder with the narrow neck clearly detected by US in the usual location before the main portal vein, four patients presented retrohepatic gallbladder associated with marked atrophy of the right lobe of the liver, four patients presented suprahepatic gallbladder with marked atrophy of the anterior segment of the right hepatic lobe, and one patient presented floating gallbladder that appeared like a cystic mass in the anterior abdominal wall.…”
