A technique for generating MRI-derived synthetic CT volumes (MRCTs) is demonstrated in support of adaptive liver stereotactic body radiation therapy (SBRT). Under IRB approval, 16 subjects with hepatocellular carcinoma were scanned using a single MR pulse sequence (T1 Dixon). Air-containing voxels were identified by intensity thresholding on T1-weighted, water and fat images. The envelope of the anterior vertebral bodies was segmented from the fat image and fuzzy-C-means (FCM) was used to classify each non-air voxel as mid-density, lower-density, bone, or marrow in the abdomen, with only bone and marrow classified within the vertebral body envelope...

AIM: To determine the prognostic factors associated with mortality in patients with gastric fundal variceal (GFV) bleeding. METHODS: In total, 42 patients were endoscopically diagnosed with GFV bleeding from January 2000 to March 2014. We retrospectively reviewed the patients' medical records and assessed their history, etiology of liver cirrhosis, disease conditions, treatment options for GFV bleeding, medications administered before and after onset of GFV bleeding, blood test results (hemoglobin, albumin, and bilirubin concentrations), and imaging results (including computed tomography and abdominal ultrasonography)...

Background High cumulative radiation dose in cancer patients warrants systemic examination of possible changes in bone marrow. Purpose To assess retrospectively changes in vertebral bone marrow diffusion and perfusion using intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) in hepatocellular carcinoma (HCC) patients after exposure to radiation from diagnostic imaging and interventional procedures. Material and Methods A total of 21 IVIM-DWI sets in 20 HCC patients, consisting of baseline and follow-up liver magnetic resonance imaging (MRI) with an interval less than 100 days, were reviewed after varying levels of radiation exposure from transarterial chemoembolization (TACE), multiphase liver CT, and abdominal radiography...

PURPOSE: To demonstrate and validate a technique for generating MRI-derived synthetic CT volumes (MRCTs) in support of adaptive liver SBRT. METHODS: Under IRB approval, ten hepatocellular carcinoma patients were scanned using a single MR sequence (T1 Dixon-VIBE), yielding inherently-registered water, fat, and T1-weighted images. Air-containing voxels were identified by intensity thresholding. The envelope of the anterior vertebral bodies was segmented from the fat image by fitting a shape model to vertebral body candidate voxels, then using level sets to expand the contour outward...

BACKGROUND/AIMS: The diagnosis and treatment plan for hepatocellular carcinoma (HCC) can be made from radiologic imaging. However, lesion detection may vary depending on the imaging modality. This study aims to evaluate the sensitivities of hepatic multidetector computed tomography (MDCT), magnetic resonance imaging (MRI), and digital subtraction angiography (DSA) in the detection of HCC and the consequent management impact on potential liver transplant patients. METHODS: One hundred and sixteen HCC lesions were analyzed in 41 patients who received an orthotopic liver transplant (OLT)...

BACKGROUND: Laparoscopic hepatectomy is a common procedure that has been reported frequently [1-3]. However, laparoscopic resection of tumors located in hepatic segments 5 and/or 8 remains a technically difficult procedure as it requires two transection planes [4]. Furthermore, there are a greater number of hepatic vein and glissonian pedicle branches that require a division as compared to other hepatectomy operations. In this report, we present a pure laparoscopic right anterior sectionectomy (RAS) for hepatocellular carcinoma (HCC)...

Myelolipoma is a rare tumor composed of fat and bone marrow components, most of which are located in the adrenal gland. Myelolipoma in the liver is extremely rare. To date, only 10 cases have been reported in the English-language medical literature. In one of these cases, the hepatic myelolipoma was found within a hepatocellular carcinoma (HCC). In the present study, we report the first case of the synchronous occurrence of hepatic myelolipoma and HCCs in different liver sections of one patient, a 26-year-old female who was admitted to our hospital because of a 4-d history of upper abdominal pain...

OBJECTIVES: To determine the value of a raw data-based metal artifact reduction (SEMAR) algorithm for image quality improvement in abdominal CT for patients with small metal implants. METHODS: Fifty-eight patients with small metal implants (3-15 mm in size) who underwent treatment for hepatocellular carcinoma were imaged with CT. CT data were reconstructed by filtered back projection with and without SEMAR algorithm in axial and coronal planes. To evaluate metal artefact reduction, mean CT number (HU and SD) and artefact index (AI) values within the liver were calculated...

Spontaneous rupture of hepatocellular carcinoma (HCC) is a life-threatening complication and its prognosis is significantly poor because of the high recurrence rate after initial hepatectomy. Resection of isolated extrahepatic metastasis of HCC has been advocated to obtain a possibility of long-term survival. However, it is a challenge for clinicians to detect implantation metastasis of spontaneously ruptured HCC. Accurate re-staging plays the most important role in making a decision on isolated metastasis resection...

A 29-year-old woman who underwent the Fontan procedure at 10 years of age had an incidental finding of liver masses on abdominal ultrasonography. Subsequent gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid magnetic resonance imaging showed a 15 mm hypervascular mass with washout in the hepatobiliary phase in liver segment 4 (S4), and an 18 mm hypervascular mass without washout in the hepatobiliary phase in liver segment 2 (S2). The S2 liver mass was pathologically diagnosed to be a regenerative nodule by an ultrasound-guided needle biopsy, and the S4 liver mass was pathologically diagnosed as a poorly differentiated hepatocellular carcinoma after partial hepatectomy...

BACKGROUND & AIMS: Surveillance of patients with cirrhosis increases early detection of hepatocellular carcinoma (HCC) and prolongs survival. However, its effectiveness is limited by underuse, particularly among racial/ethnic minorities and individuals of low socioeconomic status. We compared the effectiveness of mailed outreach strategies, with and without patient navigation, in increasing the numbers of patients with cirrhosis undergoing surveillance for HCC in a racially diverse and socioeconomically disadvantaged cohort...

PURPOSE: Dynamic volume perfusion CT (dVPCT) provides valuable information on tissue perfusion in patients with hepatocellular carcinoma (HCC) and pancreatic cancer. However, currently dVPCT is often performed in addition to conventional CT acquisitions due to the limited morphologic image quality of dose optimized dVPCT protocols. The aim of this study was to prospectively compare objective and subjective image quality, lesion detectability and radiation dose between mean temporal arterial (mTA) and mean temporal portal venous (mTPV) images calculated from low dose dynamic volume perfusion CT (dVPCT) datasets with linearly blended 120-kVp arterial and portal venous datasets in patients with HCC and pancreatic cancer...

Gallbladder varices are a rare form of collateralization that develop in patients with portal hypertension. We present here a case of gallbladder varices accurately diagnosed by contrast enhanced CT imaging of the abdomen and confirmed by Color Doppler Sonography. A 76-year-old patient with hepatocellular carcinoma developed portal vein thrombosis due to tumor extension during the course of treatment and was incidentally discovered to have gallbladder varices. While most commonly asymptomatic, gallbladder varices are associated with increased risk of massive bleeding, either spontaneously or during cholecystectomy...

Port-site metastasis of hepatocellular carcinoma (HCC) is extremely rare, and only one case has been reported in the English-language literature. Contamination with malignant cells along the needle tract during percutaneous biopsy or radiofrequency ablation is a well-recognized cause of HCC recurrence. Here, we describe a case of port-site metastasis after laparoscopic liver resection of HCC. The patient, who had undergone laparoscopic partial resection of the left lateral segment of the liver 18 months earlier, was diagnosed with HCC...

INTRODUCTION: The Fontan procedure (FP) has become the standard operation for patients with single ventricle physiology. However, a long period of elevated systemic venous pressure and low cardiac output after the procedure result in chronic inflammation and liver cirrhosis, which may eventually lead to the occurrence of hepatocellular carcinoma (HCC). CLINICAL FINDINGS: We described the case of a 16-year-old female who developed HCC after the FP. At 21 months, the patient received a lateral tunnel FP, and 14 years later, she began complaining of abdominal distension, telangiectasia, and fatigue...

Our objective was to study nonalcoholic fatty liver disease (NAFLD) as a relevant risk factor associated with hepatocellular carcinoma (HCC) in patients with and without cirrhosis. HCC is a common cancer worldwide that predominantly involves patients with hepatic cirrhosis. HCC has recently been linked to NAFLD, the hepatic manifestation of obesity and related metabolic disorders. This association is alarming due to the high prevalence of NAFLD globally, which may contribute to the rising incidence of HCC. A 31-year-old female with a history of dyslipidemia, hypertension, and diabetes mellitus presented with abdominal pain that persisted for six months...

Solitary extramedullary plasmacitomas (SEMP) of the liver are very rare. We report the case of an elderly woman with a huge symptomatic SEMP of the liver mimicking hepatocellular carcinoma (HCC). The patient was a 89-year-old woman who presented with severe abdominal pain and a huge solid mass in the right hypochondrium. The laboratory data on admission revealed normal liver function tests. A multiphasic computed tomography (CT) showed a huge solid mass of the left hemiliver, hypoattenuating on noncontrast images, dishomogeneously hyperenhancing in the late arterial phase, with washout in the portal venous and equilibrium phases...

Advanced hepatocellular carcinoma (HCC) with tumor thrombi invading the portal vein and extending into the right atrium (RA) through the hepatic vein is regarded as a terminal-stage condition. Intracardiac tumor thrombus and treatment via liver resection has been reported in the current literature, but results from this therapeutic approach remain unsatisfactory. The present study describes a rare case of HCC with metastatic portal vein, middle hepatic vein, inferior vena cava (IVC) and RA tumor thrombi, and pulmonary metastases...

Hereditary haemochromatosis is a multisystem disorder of iron metabolism. Hepatic manifestations include hepatomegaly, cirrhosis and hepatocellular carcinoma. Hepatocellular carcinoma is almost always preceded by cirrhosis. We present a case of an 83-year-old man without history of liver disease or iron overload who presented with abdominal pain. Workup revealed mildly elevated transaminases, ferritin of 3996 and a solitary liver tumour. Biopsy was consistent with hepatocellular carcinoma in a background of haemosiderosis without cirrhosis...
