We report a case of ciliated hepatic foregut cyst which was incidentally found in a 64 year-old man. The cyst, 6 cm in diameter, was unilocular, solitary and was located in the medial segment of left lobe, just below the Glisson's capsule. Microscopically, the cyst wall consisted of 4 layers; pseudostratified ciliated columnar epithelium, subepithelial loose connective tissue, smooth muscle bundles and an outermost fibrous capsule. Although cartilage or subepithelial sero-mucous glands were absent, the morphologic features of the cyst correspond with those of an incomplete form of brochogenic cyst.

Autosomal dominant polycystic kidney disease is a systemic disorder with cystic manifestations in the kidneys, liver, pancreas, seminal vesicles, and meninges; its noncystic manifestations affect mostly the vascular, cardiac, and connective tissues. Cardiovascular abnormalities, including mitral and aortic valvular prolapse and regurgitation and annuloaortic ectasia, have been considered important extrarenal manifestations of autosomal dominant polycystic kidney disease. But there were no reports with dilated cardiomyopathy in patients with polycystic kidney disease yet. We have experienced a case of dilated cardiomyopathy that is associated by autosomal dominant polycystic kidney disease in 40 year old male patient. Abdominal ultrasonography revealed variable sizes of multiple cysts in both kidneys and echocardiography showed the marked dilatation of left ventricle and severely depressed left ventricular systolic function (ejection fraction=19%). He was treated with diuretics intravenously and orally. Then dyspnea and abdominal distension was improved. This is the first case of dilated cardiomyopathy with autosomal dominant polycystic disease in Korea.

BACKGROUND: The laryngeal mask airway(LMA) is a new type of airway that has many advantages compared with the tracheal tube, but its potential problem might be pulmonary aspiration. This study therefore was designed to investigate the risk of pulmonary aspiration during general anesthesia using LMA. METHODS: We studied 101 patients who received general inhalation anesthesia with LMA and mechanical positive pressure ventilation for gynecological operations. Methylene blue was poured into the oropharynx after the LMA was placed, and the presence or absence of the dye staining of the larynx, tracheal and main stem bronchi with fiberoptic bronchoscope through the LMA shaft lumen was observed one and/or two hour(s) after LMA placement. RESULTS: In two out of 101 patients there was staining of the larynx with methylene blue dye. One was one hour after and the other was stained two hours after LMA placement. CONCLUSIONS: Dye staining of the larynx suggests that even mechanical positive pressure ventilation with LMA placement have the risk of pulmonary aspiration. Therefore LMA is contraindicated if the stomach is not emptied.

To know the status of sparganum (plerocercoid of Spirometra erinacei) infection in the Korean wild life, several species of wild animals were captured in Gangwon-do and examined for their status of infection with spargana. From February to December 2011, a total of 62 wild boars, 5 badgers, 1 weasel, 1 Siberian chipmunk, and 53 wild rodents were captured, and their whole muscles were examined with naked eyes for the presence of spargana worms. From the weasel and 1 wild boar, a total of 5 spargana specimens were extracted. The weasel was for the first time recorded as an intermediate or paratenic/transport host of S. erinacei in Korea, and both the weasel (Mustela sibirica manchurica) and wild boar (Sus scrofa) were added to the list of wild animals carrying spargana.

About 15 to 20% of ovarian tumors are of germ cell origin, and about 95% of these are cystic teratoma. when the teratoma is composed either entirely or predominantly of thyroid tissue, it called struma ovarii. Struma ovarii represents about 2.7% of cystic teratoma. The incidence of malignant struma ovarii is probably much less than 5% of all struma ovarii. We have observed a case of malignant struma ovarii originated from the left ovary of a 46-year-old woman, and present this case with a brief review of concerned literatures.

OBJECTIVES: To compare the diagnostic performance of a high-resolution picture archiving and communications system (PACS) workstation directly interfaced with computed radiography(CR) with laser-printed CR films in chest diseases. MATERIALS AND METHODS: Chest radiographs with (n=91) and without (n=25) abnormalities were included. Atotal of 100 abnormalities from 91 radiographs consisted of irregular lines, pneumothoraces, nodules and consolidations (25 of each). Laser-printed hard copies with dynamic range compression (DRC) were produced. InPACS, soft copies of 1760 X 2140 X 10 bits CR images were displayed on 1536 X 2048 with 8 bit gray-scale monitors.The performance of four observers was compared between laser-printed hard copies and CR images displayed on a workstation according to receiver operating characteristic analysis. RESULTS: Overall, no significant difference sin observer performance were observed between laser-printed hard copies and CR images displayed on a workstation(p=.2454). Even though statistically not significant, the former was slightly superior to the latter for lesions of irregular lines, pneumothoraces, and consolidations, whereas for nodules, the latter was slightly better than the former. CONCLUSION: The diagnostic performance of a high-resolution PACS workstation in chest radiographs is acceptable and comparable to CR hard copies printed with DRC processing mode.

BACKGROUND: We observed several cases of rare vascular anomalies within the femoral triangle during varicose vein operations. METHODS: From among 2,093 patients who underwent stripping operations of the great saphenous vein between January 2002 and June 2016, 14 cases of rare vascular anomalies were enrolled in this study. RESULTS: Twelve cases of femoral artery and vein transposition (0.57%), 1 case of separate entrance of the great saphenous vein trunk and its tributaries (0.05%), and 1 case of separate entrance with femoral artery and vein transposition (0.05%) were observed. The preoperative diagnosis rate was 71% (10 of 14) using duplex ultrasound. In all cases of femoral artery and vein transposition, the saphenofemoral junction was located at the lateral or posterolateral side of the superficial femoral artery, corresponding to complete or incomplete transposition, respectively. Among the 12 cases of femoral artery and vein transposition, 5 cases were complete transposition and 7 cases were incomplete transposition. In 2 cases of separate entrance of the great saphenous vein trunk and its tributaries, the separated tributaries formed a common trunk before connecting to the femoral vein. CONCLUSION: The anatomy of the saphenofemoral junction may infrequently be altered in some individuals. Detailed preoperative sonographic examinations and meticulous groin dissection during the operation are necessary to prepare for unexpected anatomical variations.

Endomyocardial biopsy often fails to show myocardial inflammation for patients with clinically suspected myocarditis. The serum isoforms of troponin T (cTnT) level is a very sensitive marker of myocardial injury and it is elevated even in the absence of myocardial inflammation. We investigated the correlations for myocardial injury, virus titers and inflammation in acute viral infection. Using the murine coxsackievirus group B3 (CVB3) myocarditis model, the histopathologic findings and virus titers in mouse hearts were compared with the serum cTnT levels measured by ELISA at various time points. Viable virus titers in the hearts peaked at 3 days after infection (8.22+/-0.13 log10 PFU/100 mg of heart); they decreased at day 7 and no viable virus was detected from day 14. Myocardial inflammation was minimal at day 3, peaked at day 7 and markedly decreased at day 14. The individual serum TnT levels were significantly increased at day 3 (7.37+/-1.46 ng/ml), persisted to day 7 (0.73+/-0.08 ng/ml), and normalized at day 14. Serum cTnT levels were correlatable with virus titers in the heart (r=0.744, P <0.01), but the serum cTnT levels were not correlated with the degrees of inflammation. Using the less myocarditic strain of CVB3, similar relationships were observed between the changes for the serum cTnT levels and the heart virus titers. During the course of viral infection, myocardial injury precedes the pathologic evidence of inflammation, and the elevated cTnT levels provide evidence of myocardial injury even in the absence of any histologic findings of myocarditis.
