Bifid liver presenting with anomalous quadrate and caudate lobes and a transverse gallbladder.
The current Observation reports multiple anomalies of the liver of a 55-year-old male cadaver. Observations revealed the presence of anomalies on the diaphragmatic and visceral surfaces of the liver. The diaphragmatic surface presented with a deep furrow that run obliquely from the fissure for the inferior vena cava to the inferior border of the liver. It divided the liver partially into the right and left segments that remained united by the liver tissue that measured about 0.7 cm thick. The two segments were easily pulled apart for up to 3 cm. A similar fissure did not appear on the visceral surface. The visceral surface presented with multiple anomalies that included a vertically oriented porta hepatis, abnormal Y-shaped fissures on the right lobe, transverse gallbladder, absence of the caudate process on the caudate lobe, abnormal quadrate lobe, and transverse fissure on the right lobe. The three fissures that formed a Y-shaped configuration delineated the quadrate lobe. The right and left arms of the Y-shaped fissure terminated in the porta hepatis. Congenital anomalies of the adult liver are rare; therefore continued documentation of such anomalies remains to be important in medical sciences and in the understanding of liver ontogeny.
