Inflammatory Myofibroblastic Tumor: a Possible Complication of Percutaneous Radiofrequency Ablation for Hepatocellular Carcinoma
نویسندگان
چکیده
An inflammatory myofibroblastic tumor (IMT) is an uncommon, benign lesion characterized by the mesenchymal proliferation and infiltration of inflammatory cells composed primarily of lymphocytes and plasma cells. A percutaneous radiofrequency ablation (RFA) is an effective and safe therapeutic modality used for the management of liver malignancies. Here we report, for the first time, a case of IMT as a complication of RFA for hepatocellular carcinoma in a 61-year-old man with a Child's class A hepatitis B-related liver cirrhosis. Gastrohepatic fistula formation was pathologically proven and associated with the RFA. Such a longstanding inflammation of the fistula might have been a possible cause of the development of IMT in this case.

Drop metastasis from hepatocellular carcinoma after percutaneous radiofrequency ablation therapy
For treating hepatocellular carcinoma (HCC), radiofrequency ablation (RFA), a nonsurgical locoregional therapy, is frequently chosen as the first treatment modality because it is effective and less invasive, with preservation of the remnant hepatic parenchyma. Tumor implantation along needle tract or on other sites is a rare complication of RFA. We present a patient with HCC who developed a dro...

Purpose: To evaluate the utility of artificial ascites induction for radiofrequency ablation (RFA) of peridiaphragmatic hepatocellular carcinoma (HCC) through retrospective cohort analysis comparing characteristics and complications of peridiaphragmatic HCC without the use of artificial ascites to non-peridiaphragmatic HCC. Materials and Methods: IRB approval was obtained. From September 2003 t...

A 71-year-old man was referred to us for investigation of a liver mass and adenomyomatosis of gallbladder. Findings on ethoxybenzyl diethylenetriamine-enhanced MRI (EOB-MRI) led to a presumptive diagnosis of a 1.5 cm hepatocellular carcinoma (HCC) in the right posterior lobe of the liver. Transcatheter arterial chemoembolization and radiofrequency ablation of the tumor were attempted. After 2 m...

Worldwide, hepatocellular carcinoma (HCC) is a common, refractory, malignant tumor. Surgical resection is feasible in only a few patients, because of limited hepatic reserve and multifocality of tumors at diagnosis. Percutaneous ablation therapies, including injection of ethanol (PEI) or acetic acid (PAI), radiofrequency ablation (RFA), and microwave coagulation therapy (MCT), have been the maj...
متن کاملRadiofrequency ablation combined with percutaneous ethanol injection in the treatment of hepatocellular carcinoma and portal vein neoplastic thrombosis.
In the last ten years new techniques, such as percutaneous ethanol injection (PEI) and radiofrequency ablation (RFA), have been developed for the treatment of hepatocellular carcinoma (HCC). Portal vein involvement is a complication of HCC and the role of surgical resection for HCC with tumor thrombi in the portal veins is controversial. Here we present the case of a 58-year-old man, with Child...
