the presence of tumor thrombus in the right atrium is frequently the result of direct intraluminal extension of infra-diaphragmatic malignancy into the inferior vena cava (ivc) or supradiaphragmatic carcinoma into the superior vena cava (svc). right atrial tumor thrombus with extension into both svc and ivc has not been reported in the literature. we present a patient who presented with symptom...

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 t...

Background: Ewing's sarcoma/Primitive neuroectodermal tumor (PNET) is a group of tumors with small round cells that originate from nerve stem cells. They are generally more common in children and often occur in the soft or bony tissues of the limbs, trunk, head, and neck. Ewing's sarcoma is a rare disease in the kidney and its tumor thrombosis into Inferior Vena Cava (IVC) is assumed as a very ...

objectives this study aimed to evaluate the safety and effectiveness of transarterial ethanol ablation (tea) for the treatment of hcc with pvtt. methods patients were treated with tea for pvtt under cone-beam computed tomography and traditional transarterial chemoembolization (tace) with epirubicin for intrahepatic lesions. results seventeen men were successfully treated with tace plus tea. the...

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...

Platelets are critical to hemostatic and immunological function, and are key players in cancer progression, metastasis, and cancer-related thrombosis. Platelets interact with immune cells to stimulate anti-tumor responses and can be activated by immune cells and tumor cells. Platelet activation can lead to complex interactions between platelets and tumor cells. Platelets facilitate cancer progr...

background: hepatocellular carcinoma (hcc) is a primary liver cancer that frequently causes mortalities. transarterial chemoembolization (tace) is a new palliative treatment for advanced stages of hcc. in this study, we have assessed the results of tace on a group of iranian patients with advanced hcc treated at imam khomeini general hospital. materials and methods: this was a case series, coho...

OBJECTIVE To evaluate predictors of survival time in dogs undergoing adrenalectomy and identify risk factors associated with adrenal gland tumor metastasis and vein thrombosis. DESIGN Retrospective case series. ANIMALS 52 dogs with primary adrenal gland tumors. PROCEDURES Medical records were reviewed. Signalment, tumor features, and information from surgical procedures were evaluated to ...

Pulmonary vein thrombosis has been described in several patients including those with malignancy, pulmonary veno-occlusive disease, fibrosing mediastinitis, and after lung transplantation. 1-5 Although liposarcoma frequently metastasizes to the lungs, to our knowledge pulmonary venous (tumor) thrombosis with lung infarction has not been previously mentioned as part of this disease. We report a ...
