Mesenchymal hamartoma of the liver (MHL) is a rare benign lesion occurring primarily in the pediatric population. While the precise pathogenesis of the tumor is not certain, the most common theory relates to aberrant mesenchyme development in the portal tract likely related to the bile ducts. A 53-year-old female was ...

Non-parasitic hepatic cysts are benign entities, occur rarely (5% of the population), and in the majority of cases, are asymptomatic. Cysts can cause symptoms when they become large and produce bile duct compression or portal hypertension, and also when complications such as rupture, infection or hemorrhage take place. We present ...

Hypervascular hepatocellular lesions include both benign and malignant etiologies. In the benign category, focal nodular hyperplasia and adenoma are typically hypervascular. In addition, some regenerative nodules in cirrhosis may be hypervascular. Malignant hypervascular primary hepatocellular lesions include hepatocellular carcinoma, fibrolamellar carcinoma, and peripheral cholangiocarcinoma. Vascular liver lesions often appear hypervascular ...

Liver biopsy remains the gold standard for diagnosing nonalcoholic steatohepatitis (NASH). We have recently demonstrated that plasma cytokeratin 18 (CK-18) fragment levels correlate with the magnitude of hepatocyte apoptosis and independently predict the presence of NASH. The goal of this study was to validate the use of this biomarker for ...

The caudate lobe can be the origin of primary liver tumours or the sole site of liver metastases. This lobe is anatomically divided into 3 parts: Spiegel's lobe (Couinaud's segment 1), paracaval portion (Couinaud's segment 9), and the caudate process. In this series of 4 cases, we provide a step-by-step ...
