An occasional patient has both a pressing need for visualization of the biliary system in spite of a past history of reaction to iodinated contrast media. We report a patient, who had reacted adversely to contrast media, underwent ERCP using barium sulfate in order to opacify the biliary and pancreatic duct without side effect successfully. In conclusion, ERCP using barium sulfate as a contrast material is of value in patients who are intolerant of the iodinated contrast media.

Journal of the Korean Radiological Society 1993;29(1):39-45
Six patients with twenty histologically proven neurilemmomas of the extremities were studied using magnetic resonance(MR) imaging. The size, number, signal intensity on spin-echo T1WI(TR 500-650ms/TE 14-25ms)and gradient -echo (TR 200-600ms/TE 14-20ms; flip angle 25-30)image, enhancement pattern, detectability of nerve of origin, nerve-lesion relationship, and presence of a capsule were analyzed. The masses ranged from 1 to 12cm in longitudinal diameter and originated from the median nerve, ulnar nerve, sciatic nerve, radial nerve, and tibial nerve. All the nerve tracts except for those of 5 lesions, which could not be detected due to their small diameter, were visualized as low intensity tubular structures. All visible nerve tracts were situated along the periphery of the lesion and this finding was considered to be specific for neurilemmona. All neurilemmomas were isointense with the surrounding muscle on spin-echo T1WI and hyperintense on gradient-echo image. After a GD-DTPA injection, all masses showed moderate or marked enhancement and more prominent inhomogeneity than that on nonenhanced scan. In 19 out of 20 lesions(95%), a low signal intensity capsule surrounding the masses could be seen. Four of the six patients showed multiple masses, which was unusual as neurilemmoma usually arises as a solitary mass. In conclusion, the MR findings, especially the eccentric location of the mass lesion from the nerve of origin and the presence of a capsule, were useful in making a diagnosis of neurilemmoma of the extremity and that multiple neurilemmomas were not uncommon.

Most instances of choriocarcinoma of the ovary are gestational in origin. In contrast, nongestational choriocarcinoma of the ovary is an exceedingly rare primary germ cell neoplasm that has worse prognosis than gestational neoplasm. We report a case of pure nongestational choriocarcinoma of the ovary in view of the rarity of its kind. The patient was a 35-year-old Korean unmarried woman who had suffered from vaginal bleeding and feeling of abdominal inflation for two months. The X-ray studies and CT scanning revealed a child head sized cystic mass on the right pelvic cavity and multiple nodular densities in both lung fields and the liver. The mass in pelvic cavity was excised and histologically confirmed to be a nongestational pure choriocarcinoma, arising from the right side ovary.

PURPOSE: To evaluate normal variations and thus to avoid confusion in differentiation from lesions of the accessory structures (rhomboid fossa, foramen for supraclavicular nerve, conold tubercle) of the clavicle in chest radiographs. MATERIALS AND METHODS: We studied the variations of the clavicle in 300 chest radiographs (134 men, 166 women) and 355 dry bones (right 166, left 189; 151 men, 74 women, 130 unknown sex). RESULTS: In chest radiographs, the incidence of the depressed rhomboid fossa was 229 cases (39.5%;male 52.0%, female 29.9%);the flat type was 329 cases (56.9%;male 45.7%, female 65.7%);and the elevated type was 20 cases (3.5%; male 2.4%, female 4.3%). In the dry bones, the incidence of the depressed thombold fossa was 129 cases (57.3%;male 59.6%, female 52.7%);the flat type was 65 cases (28.9%;male 24.5%, female 37. 8%) ;and the elevated type was 31 cases (13.8%;male 15.9%, female 9.5%). The incidence of the foramen for supraclavicular nerve was 0.8% in chest radiographs, and 1.4% in the dry bones. The incidence of the elevated conold tubercle was 65.1% (male 64.0%, female 65.9%) in chest radiographs, and 96.9% (male 95.4%, female 100.0%) in the dry bones. CONCLUSIONS: The incidence of the depressed rhomboid fossa in chest radiographs was higher in men and the right clavicle. The incidence of flat rhombo~d fossa in chest radiographs decreased according to increase of age. The foramen for supraclavicular nerve was occasionally found (0.8% in chest radiographs; 1.4% in the dry bones).

Sjogren's syndrome has been considered to be an autoimmune disease affecting various organs including salivary and lacrimal glands. It occurs most commonly in middle-aged women, and less than 20 cases with primary Sjogren's syndrome have been reported in children. An 11-yim-old boy presented with recurrent annular erythema on the face that had been present for 2 years. A schirmers test showed a positive result. ANA was detected at a dilution of 1:640. Anti-Ro/SSA and anti-La/SSB antibodies were also detected. On histological examination, lymphocytes were infiltrated in the periappendegeal areas as well as the papillary and reticular dernis. The skin findimg is uncommon in children, but has become a characteristic feature of childhood Sjogrens syndrome with anti-Ro and/or anti-La antibodies.

The purpose of this study was to find the distribution and measurement of compressive and tensile stress when intrusi- on arch wire is forced engage with upper canine and to analysis stress at each section through FEM. And we compare compressive and tensile ratio at each section. The results were as follows. 1. At FA point and cemento-enamel junction of upper canine, compressive and tensile force ratio is about the same. 2. At apex, compressive force is the four times as tensile force. ; In intrusion, we show root resorption at apex. 3. At Cemento-enamel junction, the compressive and tensile force show the maximun value except FA point.

Postcholecystectomy syndrome is the persistence or recurrence of symytom complex following cholecystectomy, The majority of the patients have mild symptoms. However, the cause of recurrent symptoms is often obscure and as a consequence, a plan of management is difficult to formulate. Recently ERCP has proved to be increasingly helpful in the investigation of postcholecystectomy patients. The purpose of this study was to test the effectiveness of the ERCP in the evaluation of patients with postcbiolecystectomy syndrorae. The results are as follows 1) 102 postcholecystectomy patients were studied by endoscopic retrograde cholangiopancreatography and successful cannulation with demonstration of at least one duct was achieved in 49 of 50 jaundiced patients and in 49 of 52 non-jaundiced patients. The overall success rate was 96. 1%. 2) The results of ERCP were normal in 26 patients(26.5%) and abnormal in 72 patients (73.5%), Only 3 of 50 jaundiced patients were normal, but 23 of 52 non-jaundiced patients showed no abnormal findings. 3) The most common abnormality was biliary stone in common bile duct and intrahepatic duct which were present in 51 patients(50%). Cholangitis without stone was next common finding which was in 13 patients(13%). Of the remaining patients have air biligram, 2 CBD stricture, 1 CBD aseariasis & 1 chronic pancreatitis. 4) Time lapse between onset of symptoms and cholecystectomy was variable. 31 patients were studied less than 2 years after cholecystectomy. 18 of these patients had jaundice and 13 had no jaundice. Within 2 years afte chklecystectomy, the biliary stone was most common finding which were present in 14 out of 31 patients.
