Intra- and extrahepatic bile duct can be invaded by hepatocellular carcinoma (HCC). This is infrequent in HCC, but it can directly affect the clinical manifestation and prognosis. We present eight cases of HCCs with emphasis on the incidence and features of bile duct invassion on computed tomography (CT). Over a period of 22 months, abdominal CT was performed in 186 with HCC patients. Out of these, five cases of bile duct invasion by HCC were confirmed in our hospital and three in other hospitals. The eight cases were evaluated for the type, size and location. CT features of intraductal mass and ductal dilatation were evaluated. The incidence of bile duct invasion in HCC was 2.6%. Infiltrative type of HCC was seen in seven cases and six of these had mass 5-11 cm in size. The characteristic CT findings of bile duct invasion in HCC are mass in common hepatic duct with bulging contour(8/80, multiple intraductal masses in the intrahepatic ducts (5/8), and diffuse dilatation of intrahepatic ducts (7/8).

PURPOSE: To analyze the risk factors for postoperative lymphocele, for predicting and preventing complications. METHODS: We evaluated 92 kidney transplant recipients with multidetector CT (MDCT) at 1-month posttransplantation. From admission and 1-month postoperative records, data including diabetes, dialysis type, immunosuppressant use, steroid pulse therapy, and transplantation side were collected. Lymphocele volume was measured with 3-dimensional reconstructed, nonenhanced MDCT at one month postoperatively. The correlations between risk factors and lymphocele volume and between risk factors and symptomatic lymphocele (SyL) were analyzed. The cutoff was calculated by using the receiver operating characteristic (ROC) curve for SyL volume. RESULTS: Among 92 recipients, the mean volume was 44.53 ± 176.43 cm³ and 12 had SyL. Univariable analysis between risk factors and lymphocele volume indicated that donor age, retransplantation, and inferiorly located lymphocele were statistically significant. The ROC curve for SyL showed that 33.20 cm³ was the cutoff, with 83.3% sensitivity and 93.7% specificity. On univariable analysis between risk factors and SyL, steroid pulse, inferiorly located lymphocele, and >33.20 cm³ were statistically significant. Multivariable analysis indicated that steroid pulse, >33.20 cm³, and serum creatinine level at one month were significant factors. CONCLUSION: Risk factors including donor age, retransplantation, steroid pulse therapy, and inferiorly located lymphocele are important predictors of large lymphoceles or SyL. In high-risk recipients, careful monitoring of renal function and early image surveillance such as CT or ultrasound are recommended. If the asymptomatic lymphocele is >33.20 cm³ or located inferiorly, early interventions can be considered while carefully observing the changes in symptoms.

PURPOSE: Plasma fibrin D-dimer (D-dimer) has been suggested as a potential screening marker of acute aortic syndrome (AAS) in the emergency department (ED). However, the appropriate thresholds of D-dimer for AAS have not yet been defined. Moreover, studies reporting determinants of D-dimer concentrations in AAS are scarce. METHODS: Data were collected retrospectively on patientsfor whom a D-dimer assay and enhanced computed tomography (CT) had been performed for differential diagnosis in the ED. The D-dimer assay used during the study was the quantitative latex agglutination assay. The study was conducted in a university ED with an annual census of 67,500 between March 2004 and February 2006. A receiver operating characteristics curve was used to find the optimal cutoff of the D-dimer to predict AAS in the ED. A multivariable linear regression analysis was used to identify factors associated with increased D-dimer concentrations in AAS. RESULTS: The enrolled patients (n=105) were divided into 2 groups according to enhanced CT findings: an AAS group (n=65) and a non-AAS group (n=40). The mean D-dimer level was higher in the AAS group (10.7+/-12.8 ug/mL) than in the non-AAS group (0.6+/-0.3 ug/mL)(p<0.001). The Ddimer test showed a 92.3% sensitivity, an 85.0% specificity, a 90.9% positive predictive value, an 87.2% negative predictive value, and a 90.5% accuracy for detection of AAS at a discriminate level of 1.0 ug/mL. Stratified age, smoking, extent of AAS, complications associated with AAS, and the time interval from symptoms to D-dimer testing were independently associated with D-dimer concentrations in AAS. CONCLUSION: At a discriminate level of 1.0 ug/mL, the Ddimer assay is a sensitive and specific test for the detection of AAS in the ED. D-dimer concentrations in AAS were significantly associated with stratified age, smoking, extent of AAS, complications associated with AAS, and the time interval from symptom onset to testing.
