PURPOSE: To evaluate the diagnostic accuracy of T-tube cholangiography(TTC), selective cholangiography (SC) and noncontrast CT(NCT) in the evaluation of intrahepatic stone disease. MATERIALS AND METHODS: We retrospectively analyzed the radiological findings of these methods in thirty patients with intrahepatic stones proved by percutaneous removal. Findings of each procedure were reviewed and correlated with findings of stone removal procedure. RESULTS: Detection of stones was possible in 87. 0% for TTC, 90. 0% for SC, 96. 7% for NCT(p > 0.05). Selective cholangiography was as good as or superior to 1-I'C in determining the presence and extent of the stones in all patients(p < 0. 01). NCT was better than SC in 9;as good as SC in 18;inferior to SC in 3 patients in determining the extent and location of the stones(p > 0.05). Of 12 patients who had additional findings such as biliary cirrhosis or accompanied cholangiocarcinomas, only NCT could detect the lesions in 11 patients. CONCLUSION: Although there was no statistically significant difference between NCT and SC, one procedure sometimes gave valuable informations for interventional procedure which the other could not. Thus we conclude that both procedures are complementary studies and should be done in all patients who are subjected to biliary intervention.

Aspiratian of gastric contents during anesthesia is the most common cause of maternal anesthetic death. Particularly, the parturient is predisposed to the catastrophe of aspiration for many reasons. So, the effect of cimetidine premedication on gastric pH and volume were studied. 120 ASA Class I patients scheduled for elective obstetric and gynecologic surgery were randomly divided into six groups as follows: Class A(n=80) is pregnant women scheduled for elective cesarean section. In the class A, group 1(n=20)(control group) was received no cimetidine premedication, group 2(n=20) was received cimetidine 300 mg p.o. hs. group 3(n=20) was received cimetidine 300 mg p.o. 2hrs before anesthesia, and group 4(n=20) was received cimetidine 200 mg iv 2hrs before anesthesia. Class B (n=40) is 20-40 aged non-pregnant women scheduled for elective surgery. ln the class B, group 5(n=20)(control group) was received no cimetidine premedication and group 6(n=20) was received cimetidine 200 mg iv 2hrs before anesthesia. Immediately following induction of anesthesia, the gastric fluid was obtained by suction on a nasogastric tube and its volume and pH were measured. The results were as follows: 1) When cimetidine is not premedicated, number of patient with a gastric pH less than 2,5 and gastric volume greater than 25 ml was increased in the group 1 compared with group 5. 2) In the class A, there was significant increased gastric pH and decreased gastric volume in the group 2, 3, and 4 compared with group l. 3) In the class B, there was significant increased gastric pH and decreased gastric volume in the group 6 compared with group 5. In conclusion, it would seem that the risk of aspiration pneumonitis can be increased in the pregnant women compared with nonpregnant women. The authors recommend that the incidence of severe aspiration pneumonia can be decreased by cimetidine premedication before general anesthesia even though there is any gastric aspiration.

Choroidal metastatic carcinoma is very rare. We recently experienced a case of lung adenocarcinoma which presented to the clinic with ocular symptoms. This 57-year-old Korean male patient visited the department of ophthalmology due to decreased visual acuity and pain of the left eye. On MRI scan, a nodule was attached to the retina of the left eyeball. On simple chest radiograph, a large amount of pleural effusion was noted in the left pleural cavity. Emergency enucleation of the left eyeball was done with an impression of malignant melanoma causing an intractable ocular pain. Grossly, the lesion in the eyeball was rising from the choroid. On histologic examination, tumor cells formed many irregular, small gland-like structures. The tumor cells showed alcian blue-positive mucin in the cytoplasm and glandular lumens and were positive for CEA. Chest CT scan was performed postoperatively and showed a huge mass in the left lower lobe and multiple nodular opacities in both lung fields. Bronchoscopic biopsy revealed moderately differentiated adenocarcinoma similar to that of the eyeball.

It is important to predict the prognosis of patient with cancer. Well known parameters predicting the prognosis are staged and degree of differentiation. Recently, the prognostic and diagnostic significance of silver-stained nucleolar organizer regions(Ag-NORs) and flow cytometric DNA analysis are introduced. This study aims to detect the diagnostic significance of Ag-NORs in breast lesions, and to correlate the number of Ag-NORs and cellular ploidies in breast carcinoma. In addition, the existence of heterogeneity according to the sample in the same patient is studied Sixty six paraffin blocks(two primary lesions and the two metastatic lymph nodes in 13 patients, and one primary lesion and one metastatic lymph node I 10 patients) of breast carcinoma, 30 paraffin blocks of fibroadenoma and 23 paraffin blocks of normal breast are studied. The numbe of Ag-NORs increase from normal breast(mean 1.45) through fibroadenoma(mean 1.60) to carcinoma(mean 2.43). It was significantly different between each lsions(P<0.0005). The number of Ag-NORs increased in the aneuploidy carcinoma than that in the euploidy one(P<0.05). But, there was difference between the number of Ag-NORs and DNA index according to the sample area in the same patient with carcinoma. In conclusion, the number of Ag-NORs is diagnostically significant in breast lesions and is correlated with cellular ploidies in breast carcinoma. In addition, Ag-NORs and cellular ploidies are heterogenous in the same patient.

PURPOSE: The purpose of this study is to find helpful MR findings for predicting a naplastic oligodendrogl lomas. MATERIALS AND METHODS: Retrospective analysis of 46 MR images and 37 CT scans was performed for 46 patients with pathologically-proven cerebral oligodendrogliomas. A neuropathologist graded the tumors as one of low-grade (n=16), intermediate-grade (n=l2), or anaplastic oligodendroglioma (n=18). MR imaging features were retrospectively analysed with respect to histologic grading of the tumors. RESULTS: Contrast enhancement was observed always in anaplastic group (17 /17), in a portion of intermediate-grade group (4/10) but not in low-grade group (0/14). Peritumoral edema was observed infrequently in anaplastic group (4/18) or intermediate-grade group (1/12). Cystic changes (25/46) or calcifications on CT Scans (14/37) were not related with histologic grading. Grossly identifiable hemorrhage was rare in this series (2/46). Among the various imaging features, only tumor enhancement and peritumoral edema were statistically significant for trend test (p<0.05). CONCLUSION: When considering the diagnosis of oligodendrogliomas, the presence of contrast enhancement or peritumoral edema is a helpful features suggesting anaplastic oligodendrogliomas.

PURPOSE: To describe MR findings of cerebral venous sinus thrombosis. MATERIALS AND METHODS: We reviewed 11 MR images of six patients with cerebral venous sinus thrombosis. The MR images were retrospectively analyzed in terms of location and signal intensity of the thrombi, parenchymal lesions such as hemorrhage and edema, and changes in follow-up study obtained in 4 patients. RESULTS: The thrombus in venous sinus was visualized on MRI in all six patients. The most frequently involved sites were superior sagittal sinus(n=4) and left transvere sinus(n=4). Signal intensity of the thrombus was isointense or hyperintense on both T1 - and T2-weighted images with loss of normal signal void of the sinus on all sequences in all patients. Parenchymal lesion was present in five of six cases, manifested as local hemorrhage in three and edema in three cases(one case overlapped). Local edema seen in three patients was completely resolved on follow-up study of seven to 29 days intervals. CONCLUSION: It is concluded that iso- or high signal intensity with loss of signal void in venous sinus is virtually diagnostic of venous sinus thromosis. If there are local parenchymal lesions such as hemorrhage and/or edema of unknown causes, cerebral venous sinus thrombosis should be included in differential diagnosis.
