Osteoid osteoma is characterized by an intracortical nidus with a variable amount of calcification, as well as cortical thickening, sclerosis, and bone marrow edema. When these findings are present, a diagnosis of osteoid osteoma is easily made. However, osteoid osteoma may display imaging findings that can be misleading, and it can be difficult to(More)
BACKGROUND & AIMS Transarterial chemoembolization (TACE) is an important palliative treatment for unresectable hepatocellular carcinoma (HCC), but TACE-induced ischemic injury can upregulate angiogenic factors and is associated with poor prognosis. The aim of this study was to evaluate the safety and efficacy of concurrent conventional TACE and sorafenib in(More)
OBJECTIVE The purpose of this study was to propose a new MRI grading system for cervical canal stenosis and to evaluate the reproducibility of the system. MATERIALS AND METHODS Cervical canal stenosis was classified according to the T2-weighted sagittal images into the following grades: grade 0, absence of canal stenosis; grade 1, subarachnoid space(More)
Several studies have reported that ABO blood group, hepatitis B virus (HBV) and hepatitis C virus (HCV) infection contribute to the development of pancreatic cancer. The aim of this study was to evaluate the association between these factors and pancreatic cancer in the Korean population. We retrospectively recruited 753 patients with pancreatic cancer and(More)
OBJECTIVES Chronic hepatitis B virus (HBV) infection is the most common cause of hepatocellular carcinoma (HCC) in South Korea, but a high prevalence of metabolic diseases may result in increases in the incidence of cryptogenic HCC (cHCC). We studied characteristics of the cHCC in a single-center cohort. METHODS A cohort of 1,784 HCC patients newly(More)
BACKGROUND A standard treatment for unresectable advanced-stage intrahepatic cholangiocarcinoma (IHCC) has not yet been established. Although neoadjuvant concurrent chemoradiotherapy (CCRT) and liver transplantation are associated with long-term survival in select patients, the outcomes of CCRT for advanced-stage unresectable IHCC remain unclear. The aim of(More)
OBJECTIVES This study aimed to provide further insights into the indications for adjuvant therapeutic strategies via analysis of the sites of initial recurrence after resection of gallbladder cancer (GBC) and intrahepatic (IHC) and extrahepatic cholangiocarcinoma (EHC). METHODS Patients with biliary tract cancer who underwent potentially curative(More)
BACKGROUND With the widespread use of PET/CT, incidental hypermetabolic foci unrelated to the known malignancy have been described with increasing frequency. PURPOSE To determine the frequency and clinical significance of incidental focal hypermetabolic uptake in the breast as detected by 18F-FDG PET/CT, and to explore factors differentiating benign and(More)
Lemierre's syndrome is an uncommon septic thrombophlebitis of the internal jugular vein. The authors present the case of a 52-year-old woman with literature review. She developed flu-like symptoms and fever, and then painful swelling of the left side of her neck and left arm. Contrast-enhanced computed tomography of the neck revealed thrombosis in the left(More)
The effects of bone turnover rate on subchondral trabecular changes and cartilage destruction were evaluated in an iodoacetate-induced osteoarthritis rat model. Thirty female rats were randomly divided into three groups as the ovariectomized group, the no-treatment group and the bisphosphonate medication group. Arthritis was induced by a single(More)
