In the diagnosis of head injury, Magnetic Resonance Imaging(MRI), like CT, is an effective method ofdistinguishing between intracerebral lesions. In our experience of MRI, early hematomas are almost isointense bySaturation Recovery(SR) method, so these must be perforemd with Spin Echo (SE) method for better visualization ofhematomas. Isodense subdural hematomas, which is a diagnostic dilemma on CT images, are clearly seen on MRI.Delayed hematomas or residual parenchymal lesions are better demonstrated on MRI than on CT. Direct cornal,sagittal images and multiplanar facility of MRI provides excellent visualization of the location and shape ofextracerebral collection of hematoma. For the screening of head traumas, SE method is a technique of choicebecause of its excellent sensitivity wihin limited time.

The authors made comparative studies of CT findings with upper GI series and surgical findings in 20 cases of histologically proven gastric cancers. The identification of thickening of gastric wall and local and remotemetastasis by CT was thought to be great value in treatment planning and prediction of prognosis of the patients. The results were as follows; 1. Of 20 cases, 19 cases demonstrated thickening of gastric wall. Among 3 cases suggested as early cancer on upper GI series, 2 cases demonstrated thickened gastric wall on CT and it was provedto be advanced cancer at surgery. 2. Out of 8 cases showed no definite metastasis on CT, 4 cases had malignant in filtration histologically in the regional lymph nodes. But they were less than 1.5 cm in diameter. 3. The frequency order of remote metastasis found by CT was pancreas, liver, left adrenal gland and lung in organs and retroperitoneal, regional nodes in lymph nodes.

CT was proved to be the most accurate diagnostic tool in the analysis of brain metastasis than any otherclassical methods. The authors studied CT findings of intracranial metastasis in 31 cases proven clinically andhistologically. The results were as follows; 1. Age distribution of the cases was 15 males and 16 females withpeak age of 6th decade in males and 4th decade in females. 2. Metastatic lesions were multiple in 18 cases andsingle in 13 cases. 3. The most common degree of edema was grade III, 43% of total metastatic foci. Markededematous low densities with relatively small nodular high densities in precontrast scan and variable contrastenhancement of the nodular densities were the most frequent CT findings. 4. No specific characterstics accordingto the primary cancer was noted. All four cases of choriocarcinoma showed hemorrhagic tendency.

Splenic abscess is an uncommon lesion and may be present either as a localized area of infection in the spleen or as a part of generalized sepsis. The diagnosis is difficult because of the rather nonspecific clinical picture. Hence, splenic abscess has a high mortality rate and is after diagnosed only at autopsy. Computerized tomography (CT) offers the clinician a reliable tool for the diagnosis of intra-abdominal abscess. A successful outcome is dependent on an early diagnosis and prompt treatment by splenectomy with antibiotic cover. We experienced a care of splenic abscess which was diagnosed by CT and treated by splenectomy with antibiotics. Postoperative course was relatively uneventful.

Leriche syndrome is a chronic disorder mostly in male and is a specific symptom complex due to thrombotic obliteration of the aortic bifurcation as result of an atherosclerotic change. The symptoms include 1) extreme liability to fatigue of both lower limbs; 2) symmetric atrophy of both lower limbs; 3) pallor of the legs and feets; 4) inability to maintain stable erection. There are several methods for surgical management of this disorder; 1) thromboendarterectomy with or without sympathectomy; 2) aortoiliac bypass graft; 3) aortofemoral bypass graft. Here we report a case of Leriche syndrome which was successfully managed with aortobifemoral bypass graft with Dacron and reviewed literatures on it briefly.

The aim of present study was to elucidate whether the expression of nm23 protein might be of clinical value as prognostic factor in gastric cancer. The expression of nm23 protein was analyzed using immunohistochemical method in formalin-fixed and paraffin-embedded tissue samples of 76 gastric carcinoma patients. The cytoplasmic immunoreactivity of nm23 protein were detected in 53.9%(41/76). When the immunoreactivity of nm23 protein with TNM status and other histopathologic findings were compared by using Chi-Square test, nm23 was found to have correlations with the lymph node metastasis(p=0.04), the number of metastatic lymph node, and the invasion of lymphatic vessels(p=0.007). But, it has no correlation with TNM status. The conventional prognostic factors such as the depth of invasion, lymph node metastasis, distant metastasis, Borrmann type, size of tumor, and the curability of operation was found to have strong correlation with the survival time(p<0.003). But, the expression of nm23 protein was not significantly correlated with that in survival analysis. These results showed that the expression of nm23 protein is not a useful prognostic indicator in gastric cancer.

Duplications of the stomach account for only 3.8% of gastrointestinal duplication, mainly discovered during first year of life. Etiopathogenesis is unknown. The most widely accepted theory is recannalization with fusion of longitudinal epithelial fold. The most frequent presented symptoms and signs include gastric outlet obstruction with vomiting, and palpable mass in the epigatric area. An upper gatrointestinal series usually reveals evidence of extrinsic mass effect of intramural lesion. An abdominal ultrasonographic finding is cystic mass lesion with double layer. Histologically, the wall of intramural cyst is composed of orderly layers of alimentary mucosa, submucosa, and muscle fibers. Recommended management is complete excision & simple closure of duplication without violation of the gastric lumen. In this case, 3-day old male newborn suffered from symptoms of gastric outlet obstruction, multiple gastric duplication cysts were found in pyloric canal and greater curvature. The cystic wall was composed with typical 3 layers of gastric mucosa, submucosa, and muscle fibers. The cystic wall was composed with typical 3 layers of gastric mucosa, submucosa, and muscle fibers. Surgical excision was successfully done.
