Objective(s): In this study, we aimed to describe the characteristics of portal vein tumor thrombosis (PVTT), complicating hepatocellular carcinoma (HCC) in contrast-enhanced FDG PET/CT scan. Methods: In this retrospective study, 9 HCC patients with FDG-avid PVTT were diagnosed by contrast-enhanced fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT), which is a comb...

superior vena cava syndrome is a common presentation of bronchogenic carcinoma. the mechanism of obstruction is by compression of superior vena cava by the bronchogenic tumor itself or enlarged mediastinal lymph nodes. however obstruction due to intravascular thrombosis is extremely uncommon. here, we report a rare case of a 65-year-old male smoker who presented with superior vena cava syndrome...

OBJECTIVE To evaluate the safety and efficacy of transcatheter arterial chemoembolization (TACE) in patients with infiltrative hepatocellular carcinoma (HCC) and to identify the prognostic factors associated with patient survival. MATERIALS AND METHODS Fifty two patients who underwent TACE for infiltrative HCC were evaluated between 2007 and 2010. The maximum diameter of the tumors ranged fro...

Introduction: cerebral vein thrombosis is a rare complication of nephrotic syndrome (NS).We report a known case of NS with hemorrhagic thrombosis. Case report: A boy with previous history of NS was admitted with headache and decrease of level of consciousness and his brain images were revealed hemorrhagic thrombosis Conclusions: cerebral vein thrombosis must be considered in patients with...

Text-books of medicine and of pathology often refer to the coincidence of a malignant tumor of epithelial origin and venous thrombosis. One of the earliest observers to stress this relationship was Trousseau (1) in 1865. He was especially interested in the frequency with which thrombosis of one or more peripheral veins was the first indication of the presence of a malignant tumor. Since his ser...

Since the role of angiogenesis in cancer development has been recognized, the study of anti-angiogenic or anti-vascular therapeutic agents has become increasingly important for cancer treatment. Selective thrombosis is one approach towards this goal. Since many types of carcinoma accumulate large numbers of degranulating mast cells which will release heparin, intravenously injected protamine ma...

A 74-year-old man who had undergone transcatheter arterial embolization for hepatitis C virus-related hepatocellular carcinoma (Couinaud's segment III/IV) in April 2003 and percutaneous ethanol injection for recurrence at the same site in February 2006 was found to have dilation of the intrahepatic bile duct by computed tomography in October 2008. Contrast-enhanced computed tomography and magne...

Volume 2 • Issue 1 • 2013 Introduction A case of thrombosis associated with a malignant tumor was first reported by Trousseau in 1865 [1], which supposedly resulted from chronic disseminated intravenous coagulation. Later, malignant tumors were found to occasionally accompany arterial or venous thrombosis, pulmonary embolisms, or non-infectious endocarditis [2,3]. Trousseau syndrome is associat...

Anaplastic thyroid carcinoma is an uncommon, highly aggressive malignancy usually presenting in the elderly. An eighteen year old boy was recently diagnosed as anaplastic carcinoma of the thyroid. PET/CECT scan performed for staging, revealed a large FDG avid heterogeneously enhancing thyroid mass with bilateral jugular venous thrombosis, which also showed increased FDG uptake, thus pointing to...
