Fluorodeoxyglucose (FDG) hepatic superscan refers to the diffuse intense uptake of 18F-FDG in the liver on positron emission tomography (PET), with reduced physiological activity in the brain and heart. The common causes include lymphoma and metastasis. In this case report, we describe the imaging features of tuberculosis as a rare cause of FDG hepatic superscan. PET imaging may be the only clu...

Sjögren's syndrome (SS) has the highest incidence of malignant lymphoproliferative disorders transformation among autoimmune diseases. We present a case of extranodal high grade lymphoma of the liver in a 52-year-old patient with long history of SS. Lymphoma manifested with sharp significant pain in the right hypochondrium, weakness, and profuse night sweats. Contrast-enhanced computed tomograp...

Primary hepatic malignancies are less common than metastatic diseases, but a recognition of these lesions is important for diagnosis and treatment planning. Magnetic resonance imaging (MRI) provides the most imaging information to diagnose lesions noninvasively and to narrow differential diagnoses. This paper reviews the imaging findings of chronic liver disease and primary hepatic malignancies...

CONTEXT Diffuse large B-cell lymphoma is the commonest form of non-Hodgkin lymphoma. Gastro-intestinal tract and bone marrow are common extra-nodal sites of lymphomatous involvement. CASE REPORT A 54-year-old woman presented with acute onset epigastric pain. On evaluation, raised serum amylase and radiological features of acute pancreatitis were detected. Gastroscopy revealed thickened folds ...

We explored the protective effect of ischemia preconditioning (IP) on ischemia-reperfusion injury in rat liver transplantation. An orthotopic liver transplantation model was utilized in the study. A total of 54 Sprague-Dawley rats were divided into a control group (group A, no liver transplantation), liver transplantation group (group B, heparin Ringer's lactate solution was perfused via the po...

Primary hepatic lymphoma represents <1% of extranodal lymphoma and predominantly seen in men older than 50 years of age. Exact etiology for these tumors is not certain yet, but presumed to be caused by certain viruses like Epstein-Barr virus and hepatitis C virus due to the frequent association of these viruses with disease. Most of these tumors are diffuse large B cell non-Hodgkin lymphoma. Di...

BACKGROUND Non-Hodgkin lymphoma (NHL) is a well-known hematologic malignancy. The gastrointestinal (GI) tract is the most commonly involved extra nodal site. MALT lymphomas are uncommon, accounting for 5% of all NHL. Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is the prototype seen in association with Helicobacter pylori. Colonic MALT lymphoma is rare and comprises only 2.5% of th...
