PURPOSE The aim of this study was to evaluate the tissue stiffness of solid pancreatic lesions by using acoustic radiation force impulse (ARFI) elastography to differentiate benign from malignant pancreatic lesions. METHODS ARFI elastography was performed in 26 patients who had 27 focal solid pancreatic lesions, including 8 benign lesions (mass-forming(More)
OBJECTIVE To evaluate the early clinical experience associated with radiofrequency (RF) ablation in patients with renal cell carcinoma (RCC). MATERIALS AND METHODS The RF ablation treatment was performed on 17 tumors from 16 patients (mean age, 60.5 years; range, 43-73 years) with RCC. The treatment indications were localized, solid renal mass,(More)
PURPOSE Laparoscopic liver resection (LLR) is now widely accepted and is being increasingly performed. The present study describes our experience with LLR at a single center over an eight-year period. METHODS This retrospective study enrolled 100 patients between October 2002 and February 2010. Forty-six benign lesions and 54 malignant lesions were(More)
PURPOSE Hepatobiliary surgery has changed dramatically in recent decades with the advent of laparoscopic techniques. The aim of this retrospective study was to compare survival rates according to stages, adjusting for important prognostic factors. METHODS A retrospective study of a 17-year period from January 1994 to April 2011 was carried out. The cases(More)
Differential diagnoses of hepatic nodules include hepatocellular carcinoma, focal nodular hyperplasia, hepatic adenoma, regenerative nodule, focal fatty changes, and hemangioma. However, differentiation of these nodules can often be difficult. Hemangiomas are frequently encountered during ultrasonogram incidentally and can be diagnosed easily because they(More)
BACKGROUND/AIMS The objective of our study was to identify useful computed tomography (CT) findings for differentiating fundal type adenomyomatosis from localized chronic cholecystitis involving the fundus of the gallbladder. METHODS We retrospectively identified cases of 41 patients with pathologically proven adenomyomatosis (n=21) or chronic(More)
We report a rare case of resected hepatic AML, which was misdiagnosed as hepatocellular carcinoma in a chronic hepatitis B carrier. A 45-year-old woman who was a carrier of hepatitis B virus infection presented with a hepatic tumor. Her serum alpha-fetoprotein level was normal. Ultrasonography revealed a round and well-circumscribed echogenic hepatic tumor(More)
BACKGROUND/AIMS This study was performed to investigate the correlation of sodium iodide symporter (NIS) expression with the functionality and loss of phosphatase and tensin homolog deleted on chromosome ten (PTEN) expression in human cholangiocarcinoma (CCA). METHODS Immunohistochemistry for the expression of NIS and PTEN was performed in 60 biopsy(More)
Cycloserine is a broad spectrum antibiotic used as a second drug for treatment of drug resistant tuberculosis. Inappropriate usage in excessive doses can give rise to neurological problems. We report a case who developed aphasia, anxiety and seizure during anti-tuberculosis medication. MRI of the brain showed reversible cytotoxic edema in dentate nuclei.(More)
