PURPOSE To retrospectively compare absolute and relative washout of adrenal metastases in patients with renal cell carcinoma (RCC) and hepatocellular carcinoma (HCC) to that of adrenal adenoma. MATERIALS AND METHODS Between November 1994 and August 2011, in this institutional review board-approved study (with waiver of informed consent), 16 patients with(More)
BACKGROUND/AIMS The goal of this study was to estimate the growth rate of hepatocellular carcinoma (HCC) and identify the host factors that significantly affect this rate. METHODS Patients with early-stage HCC (n=175) who underwent two or more serial dynamic imaging studies without any anticancer treatment at two tertiary care hospitals in Korea were(More)
OBJECTIVE The purpose of this article is to evaluate the utility of diffusion-weighted imaging (DWI) and blood oxygenation level-dependent (BOLD) MRI for characterizing renal cell carcinoma (RCC) subtypes at 3 T. MATERIALS AND METHODS Seventy-seven patients underwent 3-T DWI and BOLD MRI. Apparent diffusion coefficient (ADC; × 10(-3) mm(2)/s) and rate of(More)
Renal lymphangioma typically manifests as a unilocular or multilocular cystic mass in the parapelvic or perirenal spaces. A solid mass-like lymphangioma rarely occurs and thus is hard to differentiate from a renal cell carcinoma. We encountered a case of a solid mass-like renal lymphangioma that was confirmed using percutaneous biopsy. The purpose of our(More)
PURPOSE To assess the impact of latanoprost on central corneal thickness (CCT) after ceasing medication in patients with normal tension glaucoma (NTG). METHODS A total of 46 eyes from 46 NTG patients, and 44 eyes from 44 individuals with glaucoma suspect (controls), were included in this retrospective study. Newly diagnosed early NTG patients (visual(More)
A pulmonary mucinous cystadenocarcinoma is an extremely rare tumor that is considered to be a cystic variant of mucin-producing lung adenocarcinoma. We present a case of pulmonary mucinous cystadenocarcinoma in a 54-year-old woman. Chest CT scans showed a 4.3-cm-sized, lobulated, well-defined, and homogeneous mass in the right middle lobe with peripheral(More)
