Agenesis of Left Hepatic Lobe: A Rare Congenital Anomaly. Case Report

Abstract

Morphologic anomalies of the liver, as opposed to many other visceral organs, are very rare. Left lobe liver agenesis is defined as the absence of liver tissue on the left side of the liver in the absence of previous disease or surgery. It is commonly an accidental finding on imaging investigations or at the time of abdominal surgery. We report the case of left liver lobe agenesis diagnosed in a 68-year-old man with a history of urothelial carcinoma of the bladder, and the diagnosis of his liver congenital abnormality was made accidentally on a CT of chest-abdomen-pelvis (initially done to look for secondary localisations of his urothelial carcinoma). The main imaging findings of this condition are reviewed briefly, with associations and the most common differential diagnoses.
