A metastatic liver carcinoma which developed from the pons hepatis and presented as an extrahepatic mass on ultrasonography and computed tomography is reported. There have been no other reports of hepatoma documenting the extrahepatic growth developed from the pons hepatis. Herein we study the frequency of the pons hepatis and classify the form of REX's recessus. Of 125 cases that underwent upper abdominal operation, 46 cases (38%) had nothing under REX's recessus (Type I), 48 cases (37%) had a fibrous tissue under REX's recessus (Type II), and 31 cases (25%) had a pons hepatis (Type III). In Type III, some cases suggested that the pons hepatis was ready to disconnect from side to side. We conclude that Type II is a modified form of Type III, and Type I is a modified form of Type II.

Background The liver, being the largest internal organ of the body shows a variety of gross morphological variations about lobes, fissures and processes which may be clinically significant. Among various anatomical variations, the most found is the variant fissure for ligamentum teres hepatis. The present study was done to classify, review, compare and discuss the literature for anomalies in fissures for ligamentum teres hepatis.

Article Synopsis
- The liver, the largest gland in the body, displays various surface features that are important for medical procedures and imaging.
- A study of 52 human cadaveric livers in Gujarat, India, found that while 53.84% appeared normal, many showed significant variations, such as small or unusually shaped lobes, grooves, and additional fissures.
- These findings highlight the need for awareness of liver morphology variations among medical professionals, as this knowledge can improve surgical outcomes and diagnostic accuracy.

Introduction With increasing dependence on laparoscopic procedures, precise knowledge of external variations of the liver is essential for good surgical and interventional outcomes, preventing imaging misdiagnosis, and curtailing complications. The present study aims to evaluate the gross anatomical variations of the liver. Materials and Methods The 40 adult cadaveric livers of age 60-80 years were removed during the routine dissection for undergraduate medical students and examined for morphological variations in the form of size, shape, and fissures.

Purpose: Liver is divided into four anatomical lobes presenting minor fissures and invisible major fissures. The prevalence of Accessory Fissures in liver ranges widely from 6 to 94%. The morphometric analysis of individual lobes is also scarce in literature.

- The study examines variations of the umbilical fissure (UF) in the liver based on cadaver dissections and classifies them into four types.
- The research found that 55.1% of cadavers exhibited UF variants, with type IV being the most common at 33.3%.
- These anatomical variations are important for clinical practices, as they can complicate imaging interpretations and liver surgeries.
