Pleural involvement in paragonimiasis is relatively common, either unilateral or bilateral, and may occur without pulmonary parenchymal infiltrates. Common radiologic findings of pleural paragonimiasis are pleural effusion, pneumothorax, hydropneumothorax, empyema and pleural thickening. However, pleural calcification as a manifestation of paragonimiasis is a rare condition. We report two cases of paragonimiasis manifested only as pleural calcifications which were confirmed pathologically.

Gastric cancer is the most common gastrointestinal malignancy in Korea. Identification and evaluation ofgastric mass lesions and regional-distant metastases by abdominal CT scan are important for the treatment planningand prognostic implications of gastric cancer patients. Author reviewed CT scan are important for the treatemntplaning and prognostic implications of gastric cancer patients. Author reviewed CT scan of 61 cases of pathologyproven gastric cancer, retrospectively, for recent 20 months from July 1983 to Feb. 1985 at department ofradiology, Korea University, Hae Wha Hospital. The results were as follows: 1. There were 50 cases of advanced adenocarcinoma, 8 cases of early gastric cancer, 2 cases of leiomyosarcoma, and 1 case of lymphoma in total 61cases. 2. The sex ratio of male to female was 2:1. Age distribution was from 24 to 75 year old and peak incidencewas in 6th decade. 3. The most frequent site of involvement with gastric cancer was gastric antrum in 51%. 4. 48of the 50 patients with advanced gastric adenocarcinoma(96%) had a wall thickness greater than 1 cm, and all of 8cases of early gastric cancer had a wall thickness less than 1 cm. Regional lymph node tumor infiltration wasfound in 100% of gastric wall thickness greater than 2.0cm, in 64% of cases of 1.5 to 2.0cm, in 50% of cases of1.9 to 1.5cm, and 12.5% of cases of less than 1.0cm. 5. In a comparison of enlargement of reginal lymph node by CTscan to tumor infiltration of regional lymph node by histology, senitivity was 52%, specificity was 87%, and reliability was 66%. 6. The structures involved by distant metastases of these cases were the retroperitoneallymph node in 15, liver in 8, and pancrease in 3. 7. The diagnostic accuracy of CT staging was considered about68% by correlation of the surgical and histological findings. 8. The CT scan is one of the accurate and simpletool for evaluation of size, shape, extent, as well as distant metastases in the cases of gastric malignancies.

Perutaneous Transluminal Angioplasty(PTA) is an effective initial treatment modality in renovascularhypertension. For determination of PTA effect, the pulse pressure recording of renal artery is not simple ascompared with in femoral artery stenosis. We tried to evaluate the PTA effect of renal artery stenosis withtracing the pressure of distal renal artery. We used the cardiac catheterization apparatus(VR-12 Honeywell) as apressure monitor in two cases of focal renal arterial stenosis. The renal artery pressure was doubled after firstattempt of ballooning, and the pressure elevated up to 94% and 79% of aorta pressure in two cases, respectively,after third attempt. We believe that renal artery pressure monitoring is a good method of determination of PTAeffect in renovascular hypertension.

Intussusception is rare in adult and usually caused by organic lesions, although there is a singnificant numbeof so-called idiopathic cases. The diagnosis of intussusception have been made by pali abdomen, barium enema andsmall bowel series. But recently ultrasound and CT make a contribution to diagnose intussusception. CT is not theprimary means for evaluation a gastrointestinal tract abnormality but also provides yaluable informations inevaluating disorders affecting the hollow viscera of the alimentary tract. CT image of intussusception demonstratea whirl like pattern of bowel loops separated by fatty stripe correlating to the intestinal walls. Abdominal ultrasonogram was used as the initial diagnostic test in 2 cases out of total 4 cases, with abdominal mass ofunknown cause. It revealed a typical pattern, composed of a round or oval mass with central dense echoes andperipheral poor echoes. We report 4 all cases of intussusception in adult who were performed by CT and/orultrasound. All cases were correlated with barium enema examination and/or surgical reports.

Ruptured dissecting aneurysm of the vertebral artery requires a rapid treatment because of the high rate of fatal early rebleeding. Stent-assisted coil embolization has been introduced as an effective procedure for both aneurysmal occlusion and parent artery preservation. We report a case of successful urgent treatment of ruptured dissecting aneurysm using a self-expandable, intracranial stent (Neuroform(R)) and a coated coil (HydroCoil(R)).

About one tenth of all CNS neoplasms involves the brain. Due to their location in the ventricles they often present similar nonspecific clinical manifestation. Localization and differential diagnosis are dependent on radiological investigation. For the identification of specific CT characteristics of the intraventricular tumors and the differental diagnosis, we retrospectively analyzed 22 pathologically proved cases seen on CT. Important differential features included age and sex of the patient, the location within the ventricle, and the morpholgic appearance of the mass and density on CT before and after intravenous administration of contrast material. Meningiomas (4 cases) and a germinoma showed increased density on the precontrast CT scans, and demonstrated dense uniform enhancement of the postenhanced scan. Choroid plexus papillomas (3 cases) showed dense uniform contrast enhancement. Intraventricular neurocytomas (3 cases) demonstrated characteristic attachment to the septum pellucidum, confinement of the lateral and third ventricle, and calcification within the mass Colloid cysts (2 cases) showed characteristic location of anterosuperior aspect of the third ventricle. In conclusion, CT findings of intraventricular tumors are usually nonspecific. The location of the mass and the patient's age are the most helpful information in the differential diagnosis.

Recently, CT scan, CT sialogram, radionuclide imaging and ultasonogram are widely applicated in conjuctionwith conventional studies such as plain film, sialogram and arteriogram for the diagnosis of salivary glanddisease. Among them, ultrasonogram porvides safe, noninvasive, and reliable way to diagnose salivary glanddisease. Authors evaluated ultrasonographic and sialographic findings of patients with suspected salivary glanddisease in 16 cases at Korea University Hosital for 8 months. (from Dec. 1983 to Aug. 1984). The following resultsare observed. 1. Final diagnosis of 16 cases were 2 cases of stone, 1 case of pleomorphic adenoma, 2 cases ofneurilemmoma, 3 cases of chronic sialademitis, 1 case of abscess, 2 cases of Retention cyst, 1 case of psendocyst,1 case of tuberculous lymphadenopathy, and 3 cases of normal finding. 2. Diagnostic ultrasonogram providesaccurate information for the size, location and character of the lesion, and differentiates intragladular lesionsfrom extraglandular ones. 3. Ultrasonogram is one of convenient, reliable and initial modality for the diagnosisof salivary gland disease.

PURPOSE: To evaluate the specif!c radiologic findings of the dysgenesis of corpus callosum(CCD) on CT and/or MR images. MATERIALS AND METHODS: The authors reviewed retrospectively CT and/or MR images of 10 patients with CCD. After classifying CCD into partial and total type according to the degree of its development, we investigated structural abnormalities on CT and/or MR images resulting from or related to CCD and then associated anomaly. RESULTS: The most common findings of CCD on axial planes of CT and/or MR images were dilatation of posterior part of the lateral ventricles(8/10) and feature of the bodies of the both lateral ventricles(8/10) in parallel. Sagittal and coronal planes of MR demonstrated exact extent of dysgenesis of the corpus callosum(5/5) and radiating pattern of gyri in medial surface of cerebral hemisphere extending to the 3rd ventricle without interruption by cingulate sulcus(4/5). CONCLUSION:MR image of mid-sagittal plane appeared most useful in diagnosis of CCD because of its direct depiction of the whole length of corpus callosum. In most cases, however, CCD can be easily diagnosed with CT scan by characteristic findings of dilatation of the posterior part of lateral ventricles and paralleling of the lateral ventricles.
