The pathology of caudate lobe of the human liver
Object of study. The importance of a diagnostic value of caudate lobe of human liver in cases of Budd-Chiari syndrome is presented. The data represents a 42 year-old patient who had a very rear paroxysmal nocturnal hemoglobinuria. The condition has progressed to a complication of Budd-Chiari syndrome, which reveals the enlarged caudate lobe of the liver. Material. 42 years female complained of pain in the right epigastric area, enlargement of the abdomen, swelling of legs, bleeding from nose, general weakness. Lupus erythematosus and Budd-Chiari syndrome was diagnosed a year ago. There was a hepatic circulation failure, narrowing of the inferior vena cava, enlarged caudate lobe and ascites in computer tomography. Conclusion. The most common pathology of caudate lobe is its enlargement. The caudate lobe usually increases in size in cases of primary cirrhosis or hepatic veins occlusion. There are more pathological findings of cirrhosis: atrophy of the right or left hepatic lobe, changes of hepatic margins, ascites and varicose. Obstruction of hepatic veins increases the blood circulation in caudate lobe leading to its enlargement, for example in case of Budd-Chiari syndrome. Similar changes of liver can be found in chronic heart failure. The enlargement of caudate lobe can narrow the retrohepatic part of inferior vena cava.
