Malignant CNS lymphoma is a malignant intracranial tumor and in most cases they run a fulminating course if left untreated, with 3 to 5 months survival after appearance of the initial symptoms. Sixteen patients with malignant lymphoma were treated in Asan Medical Center from 1989 to 1994. All patients were underwent tissue diagnosis with subtotal resection or stereotactic biopsy and followed by cranial or craniospinal irradiation with or without systemic chemotherapy. One and three year survival rate of the patients was 88% and 78% respectively. In conclusion, addition of chemotherapy and/or cranial radiation for treatment of the CNS lymphoma may improve survival.

Brain stem hematomas, expecially due to ruptured angiographically occult vascular malformation(AOVM), are of great interest because they are potentially curable. Preoperative diagnosis has been difficult due to poor resolution of CT scans in the posterior fossa region. The advent of MRI has made the identification of the angiographically occult vascular malformation possible before surgical excision. We preset 3 cases of brainstem hematoma due to vascular malformations which wre not visualized by angiography but were diagnosted by MRI. The patients were treated surgically and vascular malformations were confirmed.

The association of nephrotic syndrome with a hypercoagulable state and vascular thrombosis is well recognized. In all adult series of nephrotics, venous thrombosis are much more common than arterial thrombosis, which has been mainly reported in children. Intracoronary thrombus is among the rarest arterial thromboses. We present a case of acute myocardial infarction in a 39-year-old women with nephrotic syndrome secondary to membranous glomeluronephritis, in which subsequent coronary angiography showed no evidence of atherosclerotic change and thrombotic occlusion in the left main coronary artery which was successfully treated with intracoronary stent and intravenous abciximab.

PURPOSE: To assess whether ring enhancements of liver metastases on Mn-DPDP enhanced, early MR images were well visualized on delayed images, as compared with those of hepatocellular carcinomas (HCC), and to investigate the detection accuracy and conspicuity of each tumor. MATERIALS AND METHODS: Twenty patients with liver metastases and 15 with HCC were studied by Mn-DPDP enhanced, T1-weighted MR images. Peripheral ring enhancement and conspicuity were investigated. Differences in detection accuracy and frequency of ring enhancement in liver metastases and HCC were assessed. RESULTS: In liver metastases (n=69), 44 cases (63.8%) without ring enhancement and 25 (36.2%) with were noted on early images. Sixteen cases (23.2%) without ring enhancement, 38 (55.1%) with ring enhancement similar to the early images, and 15 (21.7%) with prominent ring enhancement were noted on delayed images. In HCC (n=37), 36 cases (97.3%) without ring enhancement and 1 case (2.7%) with were noted on early images. There was no difference of detection accuracy in liver metastases or HCC between the 2 readings. Ring enhancement and conspicuity of each tumor were superior on delayed images. Ring enhancement in liver metastases was better seen on delayed images. CONCLUSION: Ring enhancement in liver metastases was well presented on Mn-DPDP enhanced, delayed MR images, which was useful to differentiate liver metastases from HCC.

PURPOSE: Preoperative chemoradiotherapy has become an important adjunct in the management of rectal cancer. But both systemic toxicity of chemotherapy and local effect of radiation interfere wound healing of intestinal anastomosis and ultimately may lead to anastomotic leak and septic complications. The purpose of this study is to determine the optimal time interval between preoperative chemoradiotherapy and anastmotic construction, and it was evaluated by security of anastomotic construction. METHODS: One hundred and twenty male Sprague Dawley rats weighing approximately 250 g were randomly divided into 4 groups (Control group; n=40, Group 1; n=20, Group 2; n=20, Group 3; n=40). The control group (n=20) underwent anastomotic construction at 1 week after general anesthesia without preoperative chemoradiotherapy. The experimental animals (group 1, 2, 3) received preoperative chemoradiotherapy with 5 daily dose (20 mg/kg) of 5-fluorouracil and single dose of 1500 cGy radiation at the rectosigmoid junction under general anesthesia on the day after last dose of chemotherapy. And group 1~3 subsequently underwent a laparotomy to make anastomotic construction at 1 week (Group 1), 2 weeks (Group 2), and 3 weeks (Group 3; n=20) after completion of chemoradiotherapy. The security of anastomotic construction was determined by bursting pressure, tissue hydroxyproline content, gross and microscopic findings of anastomotic area at the 5th and 10th postoperative day after anastomotic construction. To evaluate systemic toxicity after che-moradiotherapy, serial body weight and alteration of CBC were measured in the control group (n=20) and Group 3 (n=20) without anastomotic construction. RESULTS: At the 5th postoperative day, Mean bursting pressures of the all treated groups were lower than that of the control group (Control group; 88 23 mmHg, Group 1; 49 22 mmHg, Group 2; 56 17 mmHg, Group 3; 78 23 mmHg). The difference was not significant in the group 3 compared with the control group. Body weight decreased in the all treated animals. The mean body weight was lowest on the day 8 after completion of chemoradiotherapy and then it gradually increased. WBC and platelet counts also decreased in the all treated animals. WBC count was lowest on the day 1 and platelet count was lowest on the day 3 after completion of chemoradiotherapy. Mean hydroxyproline contents at the anastomotic sites in the all treated groups were higher than that of the control group, especially in the group 2 and 3. Similar histologic changes were observed in both group 3 and control group. CONCLUSION: The results suggest that the optimal time interval for safe intestinal anastomosis after preoperative chemoradiotherapy is 3 weeks or later.

The purpose of this study was to evaluate the reliability of 6-axis model surgery simulator (6AMSS) for orthognathic surgery. A rectangular parallelepiped plastic block was assembled to model-mounting plate of 6AMSS. Left-right (X), anterior-posterior (Y), up-down (Z) translation and pitching (empty set X), rolling (empty set Y) and yawing (empty set Z) rotation was planned and performed using 6AMSS. The actual translation and rotation were measured with dial gauge and precisional protractor, respectively. Comparison between the planned and actual movements of plastic block for each variable were made using paired t- test. Statistical analysis for X, Y, Z, empty set X, empty set Y and empty set Z movement have shown no significant differences between planned and actual movement (P > 0.05). This indicate that model surgery performed with the aid of the 6AMSS is accurate in 3D translation and rotation. The 6AMSS is practically useful for accurate fabrication of surgical splint for orthognathic surgery.

Accurate preoperative CT staging of renal tumor affects the therapeutic approach and aids the urologist in planning the appropriate procedure. CT staging were compared in 33 patients with pathologically confirmed stage of renal tumor. The overall accuracy of CT staging in renal cell carcinoma is 87.0%. The overall accuracy of CT staging in renal pelvis tumor is 80.0%. The major role of CT was in the evaluation of renal capsule, perirenal fat, Gerota's fascia, renal vein, inferior vena cava and lymph node for invasion. We conclude that at the present time CT is the optimal technique to stage renal tumor.
