We decribe the CT findings in a case of mediastinal hemangioma. Precontrast enhanced CT demonstrated a homogeneous soft tissue mass with weveral nodular calcifications indicating phleboliths. Contrast enhanced CT revealed some areas of enhancement similar to that of adjacent vascular structures. Hemangiomas of the mediastinum, although rare, should be included in the differential diagnosis of enhancing mediastinal masses.

OBJECTIVES: The purpose of this study was to determine the clinical significance of residual amniotic fluid volume, as measured by the amniotic fluid index(AFI), on the prediction of latency period and perinatal outcomes in patients with preterm premature rupture of the membranes(PPROM). METHODS: Study population consisted of 103 singleton pregnancies with PPROM between 24 and 34 weeks' gestation. Amniotic fluid index was determined using transabdominal ultrasound at admission. Latency period was defined as time interval in hours between admission and delivery. All medical records of mothers and neonates were reviewed. Spearman's rho rank correlation, receiver-operator characteristic(ROC) curve analysis, survival analysis and Cox's proportional hazard model were used for statistical analysis. RESULTS: There was a statistically significant correlation between latency period and AFI at admission. ROC curve analysis showed that AFI at admission had a significant predictive value in the prediction of latency period < 48 hours. Survival analysis demonstrated that AFI < 5.0 was strongly associated with the likelihood of shorter latency period, Cox's proportional hazard model indicated that AFI < 5.0 was a significant independent predictor for the occurrence of latency period < 48 hours even after adjustment of other independent variables. The patients with AFI <5.0 had a higher rate of cesarean section due to fetal distress than those with AFI > 5.0 but the incidence of chorioamnionitis was not significantly different between two groups. Comparing the perinatal mortality and neonatal morbidity including infectious morbidity between the neonates born to mothers with AFI <5.0 and those with AFI > 5.0, there was no significance after adjustment of gestational age at birth. CONCLUSION: AFI at admission has a significant correlation with latency period and predictive value in prediction of latency period in the patients with PPROM. AFI <5.0 is a independent predictor for the shorter latency period.

We reviewed forty five cases of intracranial arteriovenous malformation (AVM) who were admitted in Seoul National University Hospital within recent 7 years; thirty one patients revealed intracerebral hemorrhage and fourteen patients showed seizure or progressived focal neurologic deficit as an initial presentation. To evaluate the natural history of AVM after initial hemorrhage, out of these 45 cases, we selected 22 cases who were, operated or not, observed naturally for at least 1 year. To know the post operative course, we also selected 18 cases who were operated on. Thses two groups were compared with respect to the mortality, morbidity, frequency of rebleeding or seizure, which were 9%, 27%, 55%, 27%, in the former, and 0%, 17%, 0%, and 28% in the latter. Among the 14 patients whose initial presentation was not intracranial bleeding, 9 had seizure, 5 had progressive focal neurologic deficit, and 4 had both. During the follow-up period (average 5 years), only one patient had intracranial bleeding. Seizures in this group were relatively well controlled by regular antiepileptic regimen. Out of the 2 cases who were operated for seizure control, one had considerable degree of neurologic deficit after operation. From above evidences, we tentatively conclude that the AVM with initial bleeding should be better operated on if accessible, whereas the AVM without initial bleeding should be best managed conservatively. For a more definite conclusion, large, radomized controlled studies should be done again which, however, may meet ethical problems.

BACKGROUND/AIMS: As a tumor marker, alpha-etoprotein is widely used. Diagnositic cut-ff value is known as 400 ng/mL in sera. This study is aimed to determine the clinical features of hepatocellular carcinoma (HCC) with reference to serum AFP levels in Korean patients. METHODS: From May 1990 to March 1998, 367 patients diagnosed as HCC, hospitalized and followed-p at Hanyang University Hospital, have been retrospectively analyzed with special reference on serum AFP level at time of diagnosis. The differences in clinical, hematological, and radiological features of HCC, as well as the survival rate in the two groups have been compared. Group 1 (N=182) was defined as an AFP level lower than 400 ng/mL, group 2 (N=185) was defined as an AFP level greater than 400 ng/mL. Comparisons were made by student's t test or chi-quare test. Survival rate was calculated from the time of diagnosis by Kaplan-eier method. Survival curves were also compared using log-ank test. P values less than 0.05 were considered significant. RESULTS: The patients with serum AFP levels above 400 ng/mL showed (1) a lower mean age; (2) a higher level of AST; (3) a higher level of AST/ALT ratio; (4) a high incidence of liver cirrhosis; (5) a high incidence of portal vein thrombosis; (6) a high incidence of positive HBsAg; (7) a low incidence of anti-CV; (8) a low incidence of small HCC but high incidence of large HCC; (9) a high incidence of more advanced TNM stage; (10) a low incidence of single nodular type and high incidence of diffuse type. CONCLUSIONS: Depending on the value of AFP, HCC has some clinical features. In hepatocellular carcinoma, high levels of AFP represent young age, HBV infection more than HCV infection and advanced disease state.

Percutaneous catheter drainage of pancreatic pseudocyst is an effective and safe method of treatment. Various approaches to the pseudocyst have been used. We experienced one case of successful treatment of pancreatic pseudocyst with percutaneous catheter drainage through the kidney without complication.

The authors retrospectively reviewed the efficacy of percutaneous catheter drainage in treatment of abdominal abscess associated with fistulas. One hundred sixty four consecutive patients with abdominal abscesses drained percutaneously since 1985 at department of Radiology, Wonkwang University Hospital were studied. Among these, 13 patients were found to have fistulous communications to the biliary duct, the intestinal tract, or the renal calyx. Eleven patients (85%) were successfully treated without surgical intervention while two patients (15%) needed surgical drainage and fistulectomy. The duration of drainage ranged from 7 days to 9 months. Initial drainage of abdominal abscess was performed in the hospital, but 5 of 13 patients were discharged with a tube in place and were followed up as outpatients. In conclusion, percutaneous catheter drainage is an effective and safe means of treating abdominal abscesses with fistulas.
