Left Hepatic Lobe Agenesis With Ectopic Gallbladder

Abstract

An ectopically located gallbladder is a rare entity. Here, we present a case of an ectopic gallbladder with left hepatic lobe agenesis. In this study, we describe the case of a 56-year-old male who was a known diabetic patient. He presented with abdominal pain, which started two weeks prior. Computed tomography (CT) abdomen with contrast was advised by the primary team, which showed an incidental ectopic gallbladder along the right posterior-inferior margins of the liver. Associated with it, there was complete agenesis of the left hepatic lobe, including absent segments II, III, and IV. Most of the commonly encountered ectopic positions include intrahepatic, transverse, retrohepatic, retroperitoneal, suprahepatic, falciform ligament, or under the left liver lobe. Ectopic gallbladders have clinical significance as they alter the clinical presentation of cholecystitis. They create technical challenges during cholecystectomy and other biliary operations and cause misdiagnosis in imaging. A thorough inspection of the biliary tract in patients undergoing surgery is suggested before electrocoagulation. A radiologist must always inform the clinician about the existence of an aberrant gallbladder.

Agenesis of the Left Hepatic Lobe Accompanied by Esophagogastric Cancer: A Case Report and Literature Review

“…There are 24 males and 11 females aged 11-79 years at the time of diagnosis. The median age at diagnosis was 59.5 years [ 11 - 14 ]. Surgery was required in 23 cases (66%), including 19 laparotomy cases and four laparoscopic surgery cases.…”

Left segmental hypoplasia of liver with concomitant gallbladder agenesis

“… 3 However, to our knowledge, only associated ectopic gallbladder with left hepatic lobe agenesis is reported. 3 To the best of our knowledge and literature review, associated gallbladder agenesis with left hepatic lobe agenesis is extremely rare. The rarity of this condition and its uncertain radiological features often leads to misdiagnosis and unwarranted surgical treatments.…”

“…Initially, acquired causes of lobar absence like traumatic, vascular, infectious, carcinomatous, or metabolic should be ruled out 3 . However, to our knowledge, only associated ectopic gallbladder with left hepatic lobe agenesis is reported 3 . To the best of our knowledge and literature review, associated gallbladder agenesis with left hepatic lobe agenesis is extremely rare.…”

Agenesis of the left lobe of liver

“…The agenesis of the left lobe of the liver is a rare anomaly, which is often associated with other abnormal anatomy in previous reports, 3–8 such as gastric volvulus, ectopic gallbladder, hepatomegaly and splenomegaly, seasonal costal pain, chilaiditis syndrome. The anatomical variation of this case was mainly reflected in left hepatic agenesis and relevant vascular absence, and there were no anatomical abnormalities of other organs, such as gallbladder and colon.…”
