Characterization of Normal Caudate Lobe of the Liver in Adult Sudanese Population Using Ultrasonography

Abstract

This is cross sectional descriptive study done to evaluate normal caudate lobe of the liver by ultrasound in adult Sudanese population. The normal anatomy of the caudate lobe can create several pitfalls that may lead mistakenly to be diagnosed as a disease. Such as, the caudal margin of the caudate lobe often ends in papillary process that attaches to the caudate lobe by narrow connection. On transverse ultrasound scans the connection of the papillary process may be missed and the process thereby judged to be an enlarged lymph node or a pancreatic mass. The study was carried out in four month during the period from May to September 2016 in Abu Jubaiyha Education Hospital and Alrayan Medical Center, south kurdufan state, Sudan. The aim of this study was to characterize the normal caudate lobe shape, location, texture and size in adult Sudanese population using ultrasonography imaging. This study carried out in a sample of 50 patients (20males and 30 females) who underwent abdominal ultrasound examination for other reason without liver diseases. The data were first summarized into master sheet, and then analyzed by using statistical package SPSS version 15.0 . The main results of this study were that the caudate lobe measurements (right to left Diameter, antroposterior Diameter, caudate to right lobe ratio) and the right lobe diameter greater in male than female and increased with age and this indicate that the size of liver and caudate lobe increased as the age increased. And the most common shape of the caudate lobe was rectangular 90 %.
