We experienced 3 cases of intrahepatic duct stones detected on plain radiographs. The patients had history of multiple episodes of recurrent cholangitis. Radiographic characteristics of these stones included multiple, round or rectangular radioopaque densities surrounded by calcified rim; these densities showed a branching pattern along the intrahepatic ducts.

PURPOSE: Abdominal CT scans in patients with intraperitoneal fluid were retrospectively studied to identify characteristic features useful for differential diagnosis of various causes. MATERIALS AND METHODS: One hundred and seventy patients with intraperitoneal fluid collection were classified as categories of hepatic disease, carcinomatosis, and infectious disease. We analyzed sites of fluid collection, the presence of peritoneal thickening, omental and mesenteric fat infiltration, and lymph node enlargment. RESULTS: Intraperitoneal fluid was present in subhepatic space, subphrenic space, paracolic gutter, mesentery, and fossa of the gallbladder in decreasing order of frequency. Fluid in the gallbladder fossa was the most frequent in hepatic diseases. The fluid collection in subhepatic and subphrenic space was less frequent in infectious diseases. Peritoneal thickening was noted in infectious diseases, and carcinomatosis. Omental fat infiltration and enlarged lymph nodes were the most frequent in carcinomatosis (58% and 44%, respectively), whereas, mesenteric fat infiltration and enlarged lymph nodes were the most common in infectious diseases (61%, and 26%, respectively). CONCLUSION: The location of peritoneal fluid collection showed some lesion specific characteristics, and CT features of fat infiltration and enlarged lymph nodes of peritoneum, omentum, and mesentery were helpful for differential diagnosis between carcinomatosis and infectious diseases.

PURPOSE: Automated oscillometric blood pressure measurement is not used universally, but has a tendency to be used more frequently in pediatric areas. Reference values of blood pressure by this method were not reported on infants and children under 5 years of age in Korea. This study was performed to study normative blood pressure values by using oscillometric method, presenting 95 percentites on Korean infants and children by age, sex, and weight. METHODS: The subjects were 2,989 normal infants and children from birth to 11 years of age. Blood pressure was measured three times by automated oscillometric method. Percentile values of systolic and diastolic blood pressure were presented according to age, sex and weight. RESULTS: There were no differences in systolic and diastolic blood pressure between male and female in these age groups. Systolic and diastolic blood pressure values increased significantly with increasing age and also with increasing weight. Blood pressure was more correlated with weight than with age. CONCLUSION: Oscillometric blood pressure values in infants and children were presented by age, sex and weight. These normal blood pressure values may be useful in identifying hypertension in Korean children.

PURPOSE: We evaluated the CT criteria useful for the diagnosis of the site of bowel perforation in patients with this or mesenteric injury caused by blunt abdominal trauma. MATERIALS AND METHODS: CT findings of 26patients with blunt abdominal trauma were retrospectively analyzed by two observers who were unaware of operative findings, and the results of their analysis were compared with those findings. Twenty cases of bowel perforation found at the jejunum (8), ileum (9), and colon (3), and six cases of mesenteric injuries were confirmed byoperation. We evaluated CT findings of 1) segmental bowel wall thickening, b) focal mesenteric fat infiltration, c) loculated fluid collection and d) extraluminal air adjacent to the bowel, and in addition analyzed the locations of ascites and free air, and the associated injuries of solid organs. RESULTS: The most common finding at the site of bowel perforation was segmental bowel wall thickening (17 cases), followed by focal mesenteric fatinfiltration (12 cases), loculated fluid (12 cases) and extraluminal air ajacent to the bowel (9 cases). Segmental bowel wall thickening was present at 34 sites, and the perforations were confirmed at 17 of these(50%). Focalmesenteric fat infiltration was present at 19 sites ; the perforations were proven at 12(63%). Loculated fluid collections were confirmed at 12/20 sites(60%), and extraluminal air adjacent to the bowel at 9/12(75%). Thepositive predictive value of criteria a, b, d, c) was 100%, and the positive predictive values of a, b, c) and a,d) were 60 and 67%, respectively. We observed ascites in 16 cases and intraperitoneal free air in 8 cases, the locations of ascites and free air did not, however, significantly correlate with the perforation sites. CONCLUSION: Extraluminal air adjacent to the bowel was the most specific criterion, and segmental bowel wall thickening wasthe most sensitive criterion. of all criteria, the finding 'a, b, c, d' most accurately predicted the site ofbowel perforation.

The purpose of this study was to identify how students majoring in nursing perceive cause of cancers and the effects of diet for preventing cancers. Data for the study were collected by 651 nursing students, who were registered in the second and third year in three technical colleges and third and fourth year in two universities. The research instruments included items on general characteristics of subjects, items about the degree of perception of the frequency of cancer onset and items on the perception of mortality, risk factors, preventive diets, knowledge, and high risk factor for cancer in specific body areas. The findings of this study are as follows : 1. Almost all subjects(92.8%) reported that the frequency of cancer onset increases and that it is 93.9% for people over 40. Degree of perception about cancer mortality was low at 33.0%. 2. As far as the perception of risk factors for cancer onset was concerned, smoking, stress, heredity, family history, and alcohol were rated high, over 80.0%. Risk factor in clouding, virus, hormones, pesticides were rated as low. 3. As to the perception of risk factor for body area as associated with diet salted and scorched food were rated at 44.5% for stomach cancer, alcohol, 50.4% for liver cancer, smoking, 72.8% for lung cancer, pregnancy times, 25.3%, and marriage age, 23.0% for uterine cancer, and no delivery experience, 40% for breast cancer. 4. The knowledge score for cancer was between 12 and 36, with a mean score of 26.75(SD=4.13). There was a statistically significant difference between experience in caring for cancer patients during clinical practice and knowledge score(t=3.09, p=.002).

We report an unusual case of ectopic pancreas that appeared on radiologic images as a lobulated, submucosal mass enclosed by fat component in the gastric lower body. Although, ectopic pancreas including fat component is extremely rare, in the setting of gastric submucosal mass with containing perilesional fat, these findings should be considered in ectopic pancreas as part of the differential diagnosis.

We present a case of 44-year-old male with spontaneous right vertebral arteriovenous fistula associated with neurofibromatosis type 1. The symptom of this patient was myeloradiculopathy of which was due to compressed cervical spinal cord by enlarged epidural vein. Complete occlusion of the fistula using coils resulted in relief of the patient symptom and complete disappearance of enlarged epidural vein on follow-up MR image one month later.

Eight cases of chondroblastoma were studied by analyzing the clinical and pathologic findings. The age of eight cases ranged from 17 to 38 years old(median age, 22.7 years old). The tumors developed in the femur (3 cases), patella (2 cases), tibia( 1 case), fibula (1 case), and ulna (1 case). The mean diameter of tumors was 4.0 cm (range, 1.5 to 8.0 cm). Grossly, tumors showed grayish brown solid area with foci of secondary aneurysmal bone cyst. Histologically, the tumor cells were round or polygonal in shape with nuclear groove. And there were chondroid differentiation(7 cases), mitosis(3 cases), calcific deposits(3 cases), secondary aneurysmal bone cyst(4 cases), hemosiderin deposits(4 cases), necrosis(3 cases), vascular invasion(1 caes) and foamy histiocytes and cholesterol cleft(1 cases). All cases showed no metastasis to lymph node and distant organ. Seven cases (87.5 %) were immunoreactive for S-100 protein. None were immunoreactive for cytokeratin.

PURPOSE: To evaluate CT findings for the differential diagnosis of mechanical bowel obstruction and paralytic ileus. MATERIALS AND METHODS: Without information relating to clinical or operative findings, we retrospectively analyzed the CT scans of 24 patients with mechanical bowel obstruction and 19 patients with paralytic ileus. Final diagnosis was confirmed by operation (n=26), or by clinical symptoms, radiologic findings and follow-up study CT findings were obtained : 1) the diameter of the most dilated part of the small bowel, and the thickness and enhancing pattern of the dilated small bowel wall; 2) the diameter of the most dilated part of the descending colon and the ratio of the diameter of the small bowel to that of the descending colon; 3) the number of transitional zones, length and thickness. and 4) associated ascites and its location. RESULTS: The mean diameters of the most dilated part of the small bowel in mechanical bowel obstruction and paralytic ileus were 3.6cm and 2.9cm, respectively. The diameter of the small bowel in mechanical bowel obstruction was significantly greater than in paralytic ileus(p< .05). The mean thickness of dilated small bowel wall was 4.0mm in mechanical bowel obstruction and 2.4mm in paralytic ielus, and target-like enhancement was prominent in mechanical bowel obstruction (46%) (p< .05). he mean diameter of the most dilated part of the descending colon was not significantly different to that of the most dilated part of the small bowel, but the ratio of the diameter of the small bowel to that of the colon was 2.9 in mechanical bowel obstruction and 1.9 in paralytic ileus, respectively, which was statistically significant (p< .05). A transitional zone was seen in 23 cases (96%) of mechanical bowel obstruction and in nine (47%) of paralytic ileus. In mechanical bowel obstruction, mean transitional zone length was 2cm, shorter than that of paralytic ileus (3.4cm) (p< .05) The thickness of transitional zone and the presence of ascites and its locations were not significantly different between mechanical bowel obstrction and paralytic ileus. CONCLUSION: In the differential diagnosis of mechanical bowel obstruction and paralytic ileus, the following CT findings were considered useful : diameter of the most dilated part of the small bowel ; thickness and target-like enhancing pattern of dilated small bowel wall ; ratio of the diameter of the small bowel to that of the descending colon ; and the number of transitional zones, and their length.
