Introduction: The aim is to analyze the new anatomical variant of caudate lobe.
Materials and methods: 59 formalin fixed livers were collected from Department of Anatomy, Cochin, Kerala, India. Size, shape, accessory fissures, caudate process and papillary process of caudate lobe were noted.
Results: Rectangular shaped caudate lobe in 57.6 % (photo 1), bicornuate in 12% (photo2), pyriform in 18.6% (photo 3), inverted pyriform in 3.4%(photo 4), globular(photo 5) or heart shaped (photo 6) in remaining 10.2%. Vertical fissure extending upwards (photo 7) from lower boarder of caudate lobe was seen in 5.1%.Prominent papillary process (photo 8) was found on 3.4% cases. Oblique fissure on caudate lobe of the liver (photo 9) were found.
Conclusion: The findings of our study may be helpful for surgeons and radiologist to avoid possible errors in interpretations and subsequent misdiagnosis, and to assist in planning appropriate surgical approaches.
