Agenesis of the right lobe of the liver is a rare anomaly which may be associated with stone diseases, portal hypertension, and other congenital anomalies. The radiological differential diagnosis includes lobar atrophy due to cirrhosis or hilar cholangiocarcinoma. We present a case of agenesis of the right lobe of the liver with characteristic clinical and radiological findings.

Idiopathic noncirrhotic portal hypertension is a poorly defined clinical condition of unknown etiology. Patients present with signs and symptoms of portal hypertension without evidence of cirrhosis. The disease course appears to be indolent and benign with an overall better outcome than cirrhosis, as long as the complications of portal hypertension are properly managed. This condition has been recognized in different parts of the world in diverse ethnic groups with variable risk factors, resulting in numerous terminologies and lack of standardized diagnostic criteria. Therefore, although the diagnosis of idiopathic noncirrhotic portal hypertension requires clinical exclusion of other conditions that can cause portal hypertension and histopathologic confirmation, this entity is under-recognized clinically as well as pathologically. Recent studies have demonstrated that variable histopathologic entities with different terms likely represent a histologic spectrum of a single entity of which obliterative portal venopathy might be an underlying pathogenesis. This perception calls for standardization of the nomenclature and formulation of widely accepted diagnostic criteria, which will facilitate easier recognition of this disorder and will highlight awareness of this entity.

Accessory hepatic lobe is noted as and considered a rare disease in children. It can manifest with various symptoms and complications depending on the location, volume, type and position of the disease as presented on a child. The patient presented as a 14-month-old girl who was seen with a notable hepatosplenomegaly and portal hypertension. A diagnosis was made after taking an extensive medical history, observation and radiological examinations. The formal diagnosis was a prehepatic portal hypertension associated with accessory hepatic lobe.

Chronic liver disease is a major disorder worldwide. A better understanding of anatomy, blood flow, and pathophysiology may be a key issue for their proper management. Ultrasound (US) is a simple and non-invasive diagnostic tool in the abdominal field. Doppler mode offers real-time hemodynamic evaluation, and the contrast-enhanced US is one of the most frequently used modalities for the detailed assessment. Further development in digital technology enables three-dimensional (3D) visualization of target images with high resolution. This article reviews the wide ranges of application in the abdominal US and describes the recent progress in the diagnosis of chronic liver diseases.

A case of portopulmonary hypertension characterized by repeated syncope was retrospectively analyzed. Intrahepatic or extrahepatic factor-induced portal hypertension complicated with metabolic disorder of vasoactive substances, vascular pressure, inflammation, etc. may result in systolic and diastolic dysfunction of pulmonary arteries and systemic hyperdynamic circulation, the long-term effect of which can induce vascular remodeling and consequently, pulmonary hypertension. The pathogenic process is rather insidious. Pulmonary hypertension is clinically characterized by the raised average pulmonary artery pressure, normal pulmonary capillary wedge pressure and high pulmonary vascular resistance. Currently available therapeutic approaches include drug therapy targeting on pulmonary hypertension and liver transplantation.

Vitelline veins are a pair of embryonic structures. The veins develop the portal vein system. Serious problems occur if the vitelline vein does not regress and becomes an aneurysm. Thrombus formation in the vitelline vein aneurysm could lead to portal vein thrombosis and portal hypertension unless promptly and correctly treated. Though vitelline vein aneurysm is an extremely rare anomaly, it rapidly progresses to portal vein thrombosis that requires prompt diagnosis and treatment. We reported a case of neonatal vitelline vein aneurysm and thrombosis that was cured by prompt operation.
