Q: What is Riedel's lobe of liver?
Answer: Riedel's lobe is an anatomic variation. It can easily deceive a clinician as hepatomegaly as it extends below the level of the umbilicus. It is a right-sided tail or tongue-like downward projection from the right lobe of the liver. It is a benign condition but should be watched for as 30 percent of the population may carry it.
