The role of the long head of biceps brachii tendon in the stahilization of the head of the humerus is a highly interesting issue in recent studies. But, it is not well understood. Congenital absence of biceps long head tendon ot the hilateral shoulder joint is very rare and on review of literatures, we could not find any case reported. We experienced one case which was confirmed by magnetic resonance imaging and arthroscopic examination of the shoulder, and report it with review of literatures.

Aortoiliac aneurysm is a rare cause of ureteral obstruction. We report a case of perianeurysmal fibrosis(PAF) associated with aortoiliac aneurysm resulting in hydronephrosis. CT and MRI findigns of PAF are presented. In patient with hydronephrosis of unknown cause, PAF should be included among the differential diagnosis. The diagnosis of PAF is easily made with CT and MRI findings.

PURPOSE: The purpose of this study is to compare CO2 DSA and nonionic contrast media angiography in respect to the quality of the opacification of collaterals and incidence of side-effects in peripheral occlusive arterial disease. MATERIALS AND METHODS: Sixteen patients who were suspected to have peripheral occlusive arterial disease were performed angiography with nonionic contrast media and CO2 at the same location with the same catheter. The causes of the lesions were atherosclerosis(n=7) and Buerger's disease(n:9). CO2 DSA was compared with nonionic contrast media angiography in respect to the quality of image in the diagnosis of the lesions, opacifications of collaterals and side-effects. RESULTS: In atherosclerosis;quality of the images of CO2 DSA was same as that of nonionic contrast media angiography in 6 patients and was poor in 1 patient;opacifications of collaterals of CO2 DSA were same as that of nonionic contrast media angiography in 5 patients and was poor in 2 patients. In Buerger's disease;quality of the images of CO2 DSA was same as that of nonionic contrast media angiography in 2 patients and was poor in 7 patients;opacifications of collaterals of CO2 DSA were same as that of nonionic contrast media angiography in 1 patient and was poor in 8 patients. Leg pain was the only side-effect after CO2 injection occuring in 4 out of 16 patients. CONCLUSION: CO2 could be used as safe contrast media in patient with risk factors for nonionic contrast media and for diagnosis of the atherosclerosis in lower extremity. For the procedures such as vascular intervention reguiring large amount of contrast media CO2 could effectively replace nonionic contrast media.

PURPOSE: To evaluate clinical usefulness of magnetic resonance angiography(MRA) as a diagnostic modality and for treatment planning of intracranial arteriovenous malformations(AVM). METHODS AND MATERIALS: In 14 patients with intracranial AVM which were confirmed by operations, radiologic studies and clinical evaluations, magnetic resonance imaging(MRI), MRA and conventional angiography(CA) were retrospectively reviewed with specific regards to nidus depiction, detectability of feeding arteries and draining veins, and number and anatomic consistency of these vessles. MRA was obtained by 3 D TOF, 2 D PC, and 3 D methods with adequate VENC selection. RESULTS: Nidus of AVM was well demonstrated in MRI and MRA, and no remarkable difference in detection and size estimation of nidus among MRI, MRA and CA except 2 cases of associated intracranial hemorrhage, in which 3 D PC MRA well depicted nidus that were not visualized on MRI because of subacute hemorrhage. Feeding arteries were well demonstrated on 3 D TOF and 3 D PC MRA. Dilated draining veins were well depicted on 3 D PC MRA by scannig with adequate VENC selection, and the results were no remarkable difference compared with the ones on CA. CONCLUSION: MRA of a consecutive scan after MRI is a excellent modality for evaluation and treatment planning of intracranial AVM, and possible substitutive method for CA except for radiotherapy or transarterial embolization.

The computed tomographic(CT) findings of fourteen patients with inflammatory disease and 28 with neoplasm who had an abnormal colonic wall thickening, were retrospectively studied to establish CT criteria for each disorder in differentiating inflammatory from neoplastic lesions. According to homogeneity, density and contour of mural thickening and pericolic inflammatory change in enhanced CT scans, we classified colonic wall abnormalities into 6 patterns: I) multilayering with inner and outer hyper- and middle hypodensities, II) homogeneously hyperdense with pericolic inflammatory change, III) heterogeneously hyperdense with pericolic inflammatory change, IV) homogeneously heperdense with lobulated contour, V) heterogeneously hypodense with lobulated contour and VI) heterogeneously mixed densities with irregular lobulated contour. Type I, II and III were distinctively identified in inflammatory disease, type IV, V in neoplasm, and type VI in boty diseases. We conclude that enhanced CT could be helpful in the initial diagnosis and/or suggestion of abnormal colonic wall disease and differentiation of inflammatory from neoplastic diseases.

PURPOSE: The purpose of this study was to evaluate the utility of the CT cholangiography by using helical CT with multiplanar reformation in patients with extrahepatic biliary obstruction. MATERIALS AND METHODS: Helical CT was performed in 36 patients of extrahepatic biliary obstruction confirmed by operation or invasive cholangiography(percutaneous transhepatic cholangiography or endoscopic retrograde cholagiopancreatography). The cause of obstructions were 18 benign diseases(11 common bile duct stones, four choledochal cysts, three pancreatitis) and 18 malignant diseases(seven common bile duct carcinomas, seven pancreatic head carcinomas, three ampullary carcinomas, one periampullary duodenal carcinoma). After helical scanning through the extrahepatic bile duct, retrospective reconstruction of the helical data was performed. And then, CT cholagiogram was obtained with multiplanar reformation. We evaluated the technical success rate and the accuracy in determinating the level and the cause of the obstruction. We compared findings of the CT cholangiogram with that of operation or invasive cholangiography. RESULTS: In 100%(36/36) of cases, CT cholangiography could be obtained successfully. The accuracy of the CT cholangiography in determinating the level of the obstruction was 100%(11 cases of suprapancreatic duct, 13 cases of intrapancreatic duct, 13 cases of infrapancreatic duct and ampulla), and the accuracy in determinating the cause of the obstruction was 91.7%(all cases of 18 benign diseases, and 15 cases of 18 malignant diseases). CONCLUSION: In evaluating the obstruction of extrahepatic bile ducts, the CT cholangiography by using helical CT with multiplanar reformation is an useful noninvasive method in determinating the level.and the cause of biliary obstruction and therefore could replace t~e invasive cholangiography.

Thoracic epidural analgesia is the most effective method of managing post-thoracotomy pain. However, the catheter may be misplaced into the intrapleural, intercostal, subarachnoid, or intravascular space. Intravascular misplacement of a catheter can be detected by aspiration of blood or administration of a test dose of local anesthetic; however, these methods may result in a false-negative response. Moreover, a catheter placed in the epidural space may migrate into a blood vessel during the intraoperative period. Thus, the location of the catheter tip should always be determined before local anesthetic is administered. We report a case of intraoperative intravascular migration of a thoracic epidural catheter in a 32-year-old male who underwent left thoracotomy.

Gap junctions, which mediate rapid intercellular communication, consist of connexins, small transmembrane proteins that belong to a large family of proteins found throughout the species. Mutations in the GJB2 gene, encoding Connexin 26, can cause nonsyndromic autosomal recessive or dominant hearing loss with or without skin manifestations. A 3-yr-old Korean female and her mother presented to our clinic with diffuse hyperkeratosis of the palms and soles (May 3, 2007). Skin biopsies from the soles of both patients demonstrated histopathological evidence of palmoplantar keratoderma. The patient and a number of her maternal family members also had congenital hearing loss. The combination of congenital hearing loss and palmoplantar keratoderma, inherited as an autosomal dominant trait, led us to test for a mutation in the GJB2 gene in both patients. The results showed the R75W mutation of the GJB2 gene in both. In conclusion, the simultaneous occurrence of a GJB2 mutation in a mother and daughter suggests that R75W mutation cause autosomal dominant hearing loss presenting with palmoplantar keratoderma. To the best of our knowledge, this is the first report of a GJB2 mutation associated with syndromic autosomal dominant hearing loss and palmoplantar keratoderma in a Korean family.
