A 15-year-old spayed female Yorkshire Terrier was presented to our hospital with a history of anorexia, depression and abdominal pain. Diagnostic procedures including blood test, radiography and ultrasonography were performed. Abdominal ultrasonography revealed multiple hypoechoic cysts in the left lobe of the liver. Over time, the cysts increased in size and became more echogenic. Four days later, the rupture of the largest cyst was suspected, and hepatic abscesses with bacteria were confirmed by aspiration of the cyst. Despite surgical resection of the abscessed liver lobe, antibiotic administration, and supportive therapy, the dog died 9 days after presentation to the hospital and 4 days after the surgical procedure. The present case report described the overall diagnostic and therapeutic approaches for liver abscesses in a dog.

We'd experienced a case of primary hepatoma at medical department, Dae han Kyoyuk Ins. Company January 1985. As it was found very early stage, we made out the case long term-survival possibility unexpectedly. The conclusions we gained, making comparative-analysis of ultrasonic view and operation's view are as follows; 1. By ultrasonography, echogenicity of tumor was increased type as compared with liver parenchyme. 2. The margin of the primary hepatoma by ultrasonography encapsulated well and the extraction after operation was same. 3. The boundary of tumor was clear. 4. The space-occupying lesion in liver was solitary. 5. The affected site was left lobe of the liver. 6. We couldn't discover a little fluid echo in upper abdomen on the ultrasonography, but could see in the cul-de-sac area and it accorded with the gross finding during laparotomy. 7. The case was cholangiocarcinoma in view of pathologic histology. 8. After the operation of lobectomy. the prognosis which was passed a months was very satisfactory and she exists until present.

초음파 검사는 복강내 장기를 검사하는 대표적인 영상의학검사의 한 분야이며. 혈액검사는 체내 이상 징후를 임상화학적으로 검사하는 대표적인 방법이다. 지방간의 진단은 주로 복부초음파 검사와 혈액검사를 동시에 실시하여 수행하며 두 검사의 결과를 바탕으로 진단을 하게 된다. 이 경우에 실시하는 혈액검사의 기준은 TBIL, TC, AST, ALT, ALP, GGT, TG, HDL-C, GLU의 값이다. 본 연구에서는 초음파 영상에서 지방간 진단을 받은 환자의 혈액검사 정확성을 분석하여 두 종류의 검사간 정확도를 분석하고자 하였다. 2012년 1월부터 3월간 종합검진으로 복부초음파검사와 혈액검사를 동시에 받은 환자 1350명 중 초음파 검사상 지방간 판정을 받은 459명을 대상으로 초음파 검사와 혈액검사 결과가 동일한 경우는 459명 중 280명으로 약 60.8% 이며, 초음파 검사와 혈액검사의 결과가 서로 다른 경우는 179명으로 39.2%로 밝혀져 초음파 검사와 혈액검사의 진단 정확도는 60.8% 이었다. 이는 지방간의 초음파 진단시 종사자의 주관적 능력이 병변의 진단에 큰 영향을 미친 것으로 생각되어 지속적인 초음파 임상 교육이 필요할 것으로 사료된다.

Background/Aims The liver funtion tests(LFTs), such as aspartate aminotransferase(AST), alanine amino-transferase(ALT), r -glutamyl transferase( r -GT), have been widely used for screening tests but their low positive predictive value can cause many false positive results. To evaluate the clinical usefulness of these tests, we analyzed serial LFT results of single factory workers and compared the risk factor's in groups divided by the serial LFT results. Methods From June 2001 to October 2001, 1223 consecutive healthy workers in a single factory were enrolled and questionnaire, LFT and liver ultrasonography were performed. Previous LFT results were collected from Annual Health Examination Survey. According to the abnormalities in serial LFT, participants were classified into three groups (abnormal-in-both, alternating normal-in-both) and the risk factors were compared among these groups using multiple logistic regression Results The prevalence of LFT abnormality in a single test was 16.8% but, in serial LFT, only 5% of participants showed consistent abnormality. The risk factors for abnormal-in-both group, compared with alternating group, were liver ultrasonography abnormality such as fatty liver(odds ratio, 2.2; p=0.026) and heavy alcohol intake (more than 210g/week) (odds ratio, 7.2;P=0.064). HBsAg was not significant risk factor for any of the three groups. ConclusionIn factory workers with serial LFT abnormality, alcoholic liver disease could be the principal cause of abnormal LFT. Even if HBsAg were positive in patients with abnormal LFT, there is a possibility of another causes for LFT abnormalities such as alcoholic liver disease and nonalcoholic steatosis or steatohepatitis

비알콜성 지방간에서 지방 간염으로 진행되는 확률이 높은 중등증 이상에서 적극적인 진단과 치료가 필요하다. 이에 본 연구에서는 비알콜성 지방간을 경도, 중등증, 중증으로 나누어 GLCM 알고리즘의 컴퓨터 분석기법을 이용하여 정량적인 방법으로 분류하였다. 또한 지방간 중에서 국소지방회피영역의 초음파영상의 특징을 알아보고자 하였다. 정상, 경도, 중등도, 중증지방간, 국소적 저지방영역, 각각 80증례를 대상으로 GLCM 알고리즘의 파라미터 중에 간초음파영상의 인식률이 높은 자기상관성, 편차의 제곱, 평균의 합, 분산의 합에 대한 값을 산출하였다. GLCM알고리즘의 파라미터 인식률의 결과는 평균 97.5%로 나타났다. 국소적 저지방 영상분석의 결과는 정상실질과 가장 유사한 값을 나타내었다. 초음파검사는 일차적인 선별검사법으로 쉽게 접근할 수 있지만 숙련도에 따라 검사방법의 정확도나 결과의 일치성 부분에서 차이가 있을 수 있다. GLCM알고리즘을 적용하여 지방간 정도를 정량적으로 분류할 수 있었으며, 국소적 저지방영역은 지방침착이 되지 않은 균질한 간실질임을 예측 가능하였다. 이러한 GLCM 컴퓨터영상분석이 지방간뿐만 아니라 다른 병변의 감별에도 중요한 정보를 제공할 것으로 판단한다.

Purpose: The aim of this study is to evaluate the relationship between abdominal subcutaneous fat thickness measured by ultrasonography (US) and serum lipid profile and liver transaminases in obese children. Methods: One hundred and sixty-six children diagnosed with obesity from May 2001 to December 2013 were included in this study. Data on serum lipid profile and liver transaminases were collected from clinical records. Abdominal subcutaneous fat thickness and grade of hepatic steatosis were evaluated by US. Results: Of the 166 children, 107 were diagnosed with hepatic steatosis by US, 46 with grade I, 56 with grade II, and five children with grade III. According to the grade of hepatic steasosis, the average values of midline abdominal subcutaneous fat thickness and right flank abdominal subcutaneous fat thickness measured $2.9{\pm}0.8cm$ and $1.9{\pm}0.7cm$ in the normal group, $3.3{\pm}0.8cm$ and $2.0{\pm}0.7cm$ in grade I, $3.8{\pm}0.8cm$ and $2.3{\pm}0.8cm$ in grade II, and $4.1{\pm}0.8cm$ and $2.8{\pm}1.4cm$ in grade III, respectively. Abdominal subcutaneous fat thickness correlated with grade of hepatic steatosis (p<0.01). In addition, abdominal subcutaneous fat thickness correlated with concentration of serum lipids and liver transaminases in the age group of 12-14 years (p<0.01). Conclusion: Abdominal subcutaneous fat thickness measured by US can be used as a reliable predictor of possible hyperlipidemia and steatohepatitis in children, especially during the adolescent stage.
