What medical condition is associated with the presence of Riedel's lobe?

Riedel's lobe is considered a normal anatomical variant of the liver rather than a pathological condition. It is characterized by an extension of liver tissue that can project downward, typically seen on imaging studies such as ultrasound or CT scans. This lobe variant occurs more frequently in women and is usually asymptomatic, hence it does not imply any underlying disease or condition. It is important for clinicians to recognize this variant to avoid misdiagnosing it as a mass or a pathological condition during imaging assessments.

While cholecystitis, hepatic encephalopathy, and cirrhosis are all significant liver-related conditions, they are not associated with the presence of Riedel's lobe. Understanding the distinction between variants and true pathologies is crucial in correct imaging interpretation and avoiding unnecessary interventions.
