OBJECTIVE: To assess the value of applying MultiVane to liver T2-weighted imaging (T2WI) compared with conventional T2WIs with emphasis on detection of focal liver lesions. MATERIALS AND METHODS: Seventy-eight patients (43 men and 35 women) with 86 hepatic lesions and 20 pancreatico-biliary diseases underwent MRI including T2WIs acquired using breath-hold (BH), respiratory-triggered (RT), and MultiVane technique at 3T. Two reviewers evaluated each T2WI with respect to artefacts, organ sharpness, and conspicuity of intrahepatic vessels, hilar duct, and main lesion using five-point scales, and made pairwise comparisons between T2WI sequences for these categories. Diagnostic accuracy (Az) and sensitivity for hepatic lesion detection were evaluated using alternative free-response receiver operating characteristic analysis. RESULTS: MultiVane T2WI was significantly better than BH-T2WI or RT-T2WI for organ sharpness and conspicuity of intrahepatic vessels and main lesion in both separate reviews and pairwise comparisons (p < 0.001). With regard to motion artefacts, MultiVane T2WI or BH-T2WI was better than RT-T2WI (p < 0.001). Conspicuity of hilar duct was better with BH-T2WI than with MultiVane T2WI (p = 0.030) or RT-T2WI (p < 0.001). For detection of 86 hepatic lesions, sensitivity (mean, 97.7%) of MultiVane T2WI was significantly higher than that of BH-T2WI (mean, 89.5%) (p = 0.008) or RT-T2WI (mean, 84.9%) (p = 0.001). CONCLUSION: Applying the MultiVane technique to T2WI of the liver is a promising approach to improving image quality that results in increased detection of focal liver lesions compared with conventional T2WI.

3.A case of peripheral gangrene and osteomyelitis secondary to terlipressin therapy in advanced liver disease.
Clinical and Molecular Hepatology 2013;19(2):179-184
Variceal bleeding and hepatorenal syndrome (HRS) are serious and life-threatening complications of advanced liver disease. Terlipressin is widely used to manage both acute variceal bleeding and HRS due to its potency and long duration of action. The most severe (though rare) adverse event is ischemia. The present report describes the case of a patient with gangrene and osteomyelitis secondary to terlipressin therapy. A 71-year-old male with alcoholic liver cirrhosis (Child-Pugh B) and chronic hepatitis C was admitted due to a drowsy mental status. The patient had several experiences of orthopedic surgery. His creatinine level had gradually elevated to 4.02 mg/dL, and his urine output decreased to 500 mL/24 hr. The patient was diagnosed as having grade III hepatic encephalopathy (HE) and type II HRS. Terlipressin and albumin were administered intravenously to treat the HRS over 11 days. Although he recovered from the HE and HRS, the patient developed peripheral gangrene and osteomyelitis in both feet. His right toes were cured with the aid of rescue therapy, but his left three toes had to be amputated. Peripheral gangrene and osteomyelitis secondary to terlipressin therapy occur only rarely, and there is no specific rescue therapy for these conditions. Thus, attention should be paid to the possibility of ischemia of the skin and bone during or after terlipressin therapy.

Hepatic lymphangioma is a rare benign neoplasm. It usually occurs as a part of systemic lymphangiomatosis. Isolated hepatic lymphangioma is extremely rare. A 58-year-old woman with weight loss was referred for the evaluation of chronic renal insufficiency and hepatic mass. Abdominal computed tomography showed 3 cm sized multilobulated cystic lesion with calcification and thick septal enhancing focus in the segment V of the liver. On abdominal magnetic resonance imaging, the masses exhibited low signal intensity on the T1-weighted images and high signal intensity on the T2-weighted images. Malignant tumor could not be ruled out, and therefore, the patient underwent right anterior segmentectomy of the liver. Gross pathology reveraled a 3.0x2.2x1.5 cm mass with multichamber cyst, which was filled with mucoid material. Histologically the mass was composed of irregularly shaped vascular channels filled acellular homogeneous lymph fluids. The final diagnosis was hepatic isolated cavernous lymphangioma. Herein, we report a case of isolated hepatic lymphangioma and also review the existing literature.

BACKGROUND/AIMS: The aim of this study was to identify the parameters that could noninvasively predict the presence of esophageal/gastric varices and portal hypertensive gastropathy (PHG) in patients with chronic liver disease (CLD), and to determine the accuracy of those parameters. METHODS: We retrospectively analyzed 232 patients with CLD who underwent both upper endoscopy and liver CT within an interval of 3 months. The multidimensional index (M-Index) for spleen volume was obtained from the multiplication of splenic length, width, and thickness, as measured by computer tomography. RESULTS: The multivariate analysis revealed that platelet, albumin, and M-Index were independently associated with the presence of varices and PHG. We combined three independent parameters, and developed a varices and portal hypertensive gastropathy (VAP) scoring system (=[platelet count (/mm3)xalbumin (g/dL)]/[M-Index (cm3)]). The area under the receiver operating characteristic curve of the VAP score was 0.850 (95% confidence interval, 0.801-0.899). The VAP cut-off value of 861 had a sensitivity of 85.3%, a positive likelihood ratio of 3.17, and a negative predictive value of 86.4%. For predicting high-risk lesions for bleeding, with a cut-off value of 861 the sensitivity was 92.0%, the positive likelihood ratio was 2.20, and the negative predictive value was 96.4%. CONCLUSIONS: The VAP score can predict the presence of varices and PHG in patients with CLD and may increase the cost-benefit of screening endoscopy in the clinical practice setting. A prospective validation study is necessary in the future.

Hepatic peribiliary cysts (HPCs) are characterized by cystic dilatations of the peribiliary glands located throughout the branches of the biliary systems. Specifically, they are mainly located along the hepatic hilum and major portal tracts. The natural history and prognosis of HPCs are uncertain. In fact, almost all HPCs have been discovered incidentally during radiological examination or autopsy, and they are considered to be clinically harmless. Recently, several cases of HPCs associated with obstructive jaundice or liver failure were reported in patients with pre-existing liver disease in several studies. However, until now there have been no reports of such a case in Korea. Herein, we report a case of HPCs that show a disease course with a poor prognosis. These HPCs developed in a 47-year-old man with progressive alcoholic liver cirrhosis.

A 63-year-old man with a history of hepatitis-B-related hepatocellular carcinoma (HCC) in the left lateral portion of the liver received repeated transcatheter arterial chemoembolization (TACE) and salvage radiotherapy. Two months after completing radiotherapy, he presented with dysphagia, epigastric pain, and a protruding abdominal mass. Computed tomography showed that the bulging mass was directly invading the adjacent stomach. Endoscopy revealed a fistula from the HCC invading the stomach. Although the size of the mass had decreased with the drainage through the fistula, and his symptoms had gradually improved, he died of cancer-related bleeding and hepatic failure. This represents a case in which an HCC invaded the stomach and caused a hepatogastric fistula after repeated TACE and salvage radiotherapy.

BACKGROUND/AIMS: Transient elastography as performed using the Fibroscan(R) is a useful noninvasive method for evaluating hepatic fibrosis. However, recent studies have found that liver stiffness measurement (LSM) values are inappropriately elevated in acute hepatitis or in the acute flare state of chronic hepatitis, suggesting that the LSM value obtained by the Fibroscan(R) is not a reliable marker for fibrosis. We retrospectively evaluated the clinical factors influencing the LSM value obtained using transient elastography as performed using the Fibroscan(R) in patients with chronic liver disease. METHODS: A total of 298 patients who were followed in Kungpook National University Hospital from November 2007 to May 2008 due to previously established liver cirrhosis or chronic liver disease were investigated using the Fibroscan(R), laboratory test, ultrasound, and/or abdominal computed tomography. RESULTS: The 298 patients were aged 47.8+/-12.9 years (mean+/-SD). The cut-off value for a diagnosis of liver cirrhosis was 12.5 kPa (as used in previous studies). Thirty-six patients (15%) and 202 patients (85%) with chronic liver disease without clinical manifestation of cirrhosis had LSMs of >12.5 kPa and <12.5 kPa, respectively. Multivariate analysis revealed that LSM values were unusually increased in patients with chronic liver disease who were older (P=0.007) or who had increased gamma gultamyltranspetidase (GGT) (P=0.022), decreased albumin (P=0.015), or increased total bilirubin (P=0.009). CONCLUSIONS: This study reveals that age, GGT, and albumin are clinical factors influencing LSM values. This reinforces the need to interpret LSM values in the context of a defined diagnosis, biochemical data, radiologic examination, and other clinical findings.
