OBJECTIVE: Our aim is to evaluate the usefulness of fluid-attenuated inversion recovery(FLAIR) magnetic resonance(MR) imaging for detection of acute intraventricular hemorrhage(IVH) compared with pre-contrast computed tomography(CT). METHODS: Twenty-eight patients with acute IVH were evaluated with FLAIR MR imaging and precontrast CT. All MR and CT examination were performed within two days from symptom onset. One neurosurgeon and one radiologist evaluated the detectability and conspicuity of acute IVH on FLAIR MR imaging and pre-contrast CT. RESULTS: Acute IVH was detected in all patients on FLAIR MR imaging and in 23(82%) of 28 patients on pre-contrast CT. The conspicuity of IVH on FLAIR MR imaging was as good as or better than that on pre-contrast CT in 28 patient. CONCLUSION: It is suggested that FLAIR MR imaging is superior to pre-contrast CT in the diagnosis of acute IVH.

This study is a retrospective clinical analysis of two hundred forty-four consecutive cases of acute subdural hematoma which were confirmed by operation during the last five years at the Department of Neurosurgery of the Dong-guk University Hospital. The authors have attempted, through this analysis to identify the factors affecting the outcome of acute subdural hematoma. A favorable outcome occurred in 40%, and an unfavorable outcome in 21% of patients at the time of discharge while a death ocurred in 39% of the cases. We have concluded that initial GCS, pupillary status, systolic arterial blood pressure, FDP vaules, presence or absence of skull fracture. IICP findings on brain CT, hematoma amount, and associated intracranial lesions are all prognostic factors, although the timing of operation did not reflect a significant difference in the outcome, however the sooner the intracranial hematoma lesion is evacuated, the better the outcome will be.

PURPOSE: To evaluate the efficacy of superselective intra-arterial fibrinolysis for acute cerebral stroke and the usefulness of pre- and postfibrinolysis diffusion-weighted MRI (DWI). MATERIALS AND METHODS: In 41 patients with acute ischemic stroke whose treatment involved intra-arterial fibri-nolysis, the occlusion site, degree of recanalization, and clinical results were compared. In 12 patients, diffusion weighted MRI was performed before fibrinolysis, and eight of these also underwent diffusion-weighted MRI after fibrinolysis. Using diffusion-weighted MRI, neurological outcomes were compared with signal intensity ratio (SIR, or the average signal intensity within the region of interest divided by that in the contralateral, nonischemic, homologous region). RESULTS: Twenty patients showed complete recanalization, nine partial recanalization, and in twelve there was no recanalization. Fourteen patients (34 %) improved neurologically. No relationship existed between occlusion sites, degree of recanalization, and clinical outcome. Among 12 patients who underwent DWI before fibrinolysis, complete recanalization was noted in eight. Neurological improvement was seen in four patients with low SIR(<1.55),while in four with high SIR(>1.7 ), neurological outcome was poor despite complete recanalization. CONCLUSION: Although superselective intra-arterial fibrinolysis for acute cerebral stroke is a good therapeutic method for recanalization, the clinical outcome can be disappointing. We therefore suggest that in cases of acute cerebral ischemic infaret, SIR-as seen on DWI-might be useful for predicting the benefits of recanalization. In such cases, further investigation of the use of DWI prior to fibrinolysis is therefore needed.

Surgical clips can migrate into the biliary tract and act as a nidus for stone formation. We report a case of common bile duct stone developed due to a surgical clip in a 48-year-old man. Endoscopic retrograde cholangiogram revealed a common bile duct stone a with metallic clip in it. He had laparoscopic cholecystectomy 10 years ago. The stone was removed endoscopically. The use of resorbable clips during laparoscopic cholecystectomy is recommended to avoid this type of complication.

OBJECTIVE: The goal of this study is to evaluate the incidence and factors of hematoma enlargement in patients with spontaneous intracerebral hemorrhage(ICH). METHODS: We analyzed 149 cases with spontaneous ICH who underwent computerized tomography (CT) scans from January, 1995 to December, 1998. The clinical characteristics, past medical history, laboratory findings, time intervals between onset of ICH and CT scan, CT findings and results of treatment were reviewed. RESULTS: Of the total 149 patients, 28(18.8%) had hematoma enlargement, of whom 24(85.7%) underwent a first CT scan within 3 hours after onset of ICH. The incidence of hematoma enlargement significantly decreased in patients who had CT scans 3 hours later after attack. Age, sex, and site of hematoma were not related to hematoma enlargement. Patients with an irregularly shaped hematoma, inhomogenous hematoma and large hematoma had a high risk of hematoma enlargement. Hematoma enlargement was associated with a poor clinical outcome and high mortality(46.7%). CONCLUSION: Patients admitted to a hospital within 3 hours of onset of ICH, and patients with inhomogenous hematoma on CT scan, irregularly shaped hematoma, or large hematoma should be closely observed for hematoma enlargement.

Intussusception frequently occurs in children as the main causes of intestinal obstruction in childhood but relatively rare in adult. A 65-year-old male visited our hospital because of abrupt onset right lower quadrant pain with tenderness for three days. He had a previous history of appendectomy and alcoholic liver cirrhosis. On physical exam, bowel sound was decreased. Abdomen ultrasonography showed a kidney like mass and abdominal computed tomography revealed the typical target lesion in the ileocecal area. Colonoscopy was performed which failed to find any lesion leading to intussusception. After the colonoscopy, the abdminal pain had disappeared, and we would not find any intussusception sign by abdominal ultrasonography. Colonocopy was done two weeks later. No pathologic lesion was found, then. We report a case of adult idiopathic ileocecal intussusception reduced by colonoscopy.
