Liver with vessels and gallbladder - Erler Zimmer

The size and configuration of this specimen exhibit some deviations from the characteristics of a typical liver. It appears less wedge-shaped and exhibits greater length in the superoinferior dimension (which would result in increased vertical height on the posterior view). Ordinarily, a liver measures less than 16cm in the midclavicular line. In this instance, the specimen registers at approximately 18cm in the midclavicular line, suggesting a potential degree of hepatomegaly. Nonetheless, it is important to note that the accuracy of liver size estimation based on a single parameter may be affected by distortions stemming from specimen fixation and curation. Furthermore, it is essential to recognize that the determination of hepatomegaly through a sole measurement parameter is constrained due to the normal anatomical variability in liver size and morphology, the methodology employed for measurement, and patient-specific factors such as sex and BMI.
An alternate explanation may be attributed to typical anatomical variation. Nevertheless, this specimen does not conform to the characteristics of the most frequently encountered anatomical variations often mistaken for hepatomegaly, including Riedel’s lobe (a downward projection of the right lobe), a 'beaver tail' liver (an elongated left lobe), or a papillary process projecting from the caudate lobe.
