STUDY DESIGN: A case report. OBJECTIVES: To report the case of a patient whose preoperative imaging results seemed to show metastatic spine tumor but who actually had a vertebral pathologic fracture caused by spine tuberculosis. SUMMARY OF LITERATURE REVIEW: Tuberculosis spondylitis is classified into peridiscal, central, anterior, and posterior spondylitis according to the portion involved, and central spondylitis can be mistaken as a tumor. MATERIALS AND METHODS: Imaging studies were performed in a 79-year-old female with progressive lower extremity weakness. We found a T12 pathologic vertebral fracture, which was suspected to be metastatic cancer. RESULTS: We performed surgery and found spine tuberculosis in the pathological and immunological examinations. Two weeks postoperatively, the patient could walk with crutches and underwent anti-tuberculosis therapy. CONCLUSIONS: Even when the results of imaging studies predict spinal metastasis, we should keep in mind the possibility of spinal tuberculosis.

OBJECTIVE: The purpose of this study is to examine the difference between the numbers of patients in rheumatoid arthritis (RA) who are eligible to TNF inhibitors by the past Korean National Health Insurance reimbursement guideline and by the disease activity score with 28-joint assessment (DAS28) based criteria. METHODS: Data were obtained from a multi-center registry for biologics users in Korean RA patients, BIOlogics Pharmacoepidemiologic StudY (BIOPSY). DAS28 was calculated based on either ESR or CRP, and DAS28 of more than 5.1 or between 3.2 and 5.1 with radiographic changes was defined as a cut-off point for the initiation of TNF inhibitors. For the maintenance criteria, we used both of improving in DAS28 score (>1.2) and low disease activity (DAS 28<3.2). Differences between the numbers in each step by two criteria were described with Chi-square test and Kappa agreement. RESULTS: Of the 489 patients in BIOPSY, 299 were included in this study. Among them, 278 patients (93.0%) were eligible of TNF inhibitors when we applied the new initiation criteria with DAS28-ESR, and 244 patients (81.6%) were indicated for TNF inhibitors with DAS28-CRP. For the maintenance criteria, a low disease activity (DAS28<3.2) in 3 months after starting TNF inhibitors is too strict for achieving (33.6% with DAS28-ESR and 50.0% with DAS28-CRP). Instead, decreasing DAS28 by more than 1.2 is more reasonable as a tool for deciding early responsiveness of TNF inhibitors in RA patients (81.2% both with DAS28-ESR and DAS28-CRP). CONCLUSION: Our results show that the candidates for TNF inhibitors will be enormously changed according to a change in the reimbursement criteria. To define appropriate patients to receive TNF inhibitors, a further study with regard to the impact of changes in the reimbursement criteria on the outcomes of RA patients will be required.

Few cases of macrophage activation syndrome (MAS) or reactive hemophagocytic lymphohistiocytosis (HLH) during the acute febrile phase of Kawasaki disease (KD) have been reported. We report on a case of a 19 month-old girl with MAS or reactive HLH during the course of KD. Despite immunoglobulin and steroid therapy, she showed persistent fever with hepatosplenomegaly and evidence of hemophagocytosis in the bone marrow. A high index of suspicion for clinical features associated with MAS is necessary for KD patients in order to provide appropriate treatment.

PURPOSE: Bone metastasis in breast cancer patients are usually assessed by conventional Tc-99m methylene diphosphonate whole-body bone scan, which has a high sensitivity but a poor specificity. However, positron emission tomography with 18F-2-deoxyglucose (FDG-PET) can offer superior spatial resolution and improved specificity. FDG-PET/CT can offer more information to assess bone metastasis than PET alone, by giving a anatomical information of non-enhanced CT image. We attempted to evaluate the usefulness of FDG-PET/CT for detecting bone metastasis in breast cancer and to compare FDG-PET/CT results with bone scan findings. MATERIALS AND METHODS: The study group comprised 157 women patients (range: 28~78 years old, mean+/-SD=49.5+/-8.5) with biopsy-proven breast cancer who underwent bone scan and FDG-PET/CT within 1 week interval. The final diagnosis of bone metastasis was established by histopathological findings, radiological correlation, or clinical follow-up. Bone scan was acquired over 4 hours after administration of 740 MBq Tc-99m MDP. Bone scan image was interpreted as normal, low, intermediate or high probability for osseous metastasis. FDG PET/CT was performed after 6 hours fasting. 370 MBq F-18 FDG was administered intravenously 1 hour before imaging. PET data was obtained by 3D mode and CT data, used as transmission correction database, was acquired during shallow respiration. PET images were evaluated by visual interpretation, and quantification of FDG accumulation in bone lesion was performed by maximal SUV(SUVmax) and relative SUV(SUVrel). RESULTS: Six patients(4.4%) showed metastatic bone lesions. Four(66.6%) of 6 patients with osseous metastasis was detected by bone scan and all 6 patients(100%) were detected by PET/CT. A total of 135 bone lesions found on either FDG-PET or bone scan were consist of 108 osseous metastatic lesion and 27 benign bone lesions. Osseous metastatic lesion had higher SUVmax and SUVrel compared to benign bone lesion(4.79+/-3.32 vs 1.45+/-0.44, p=0.000, 3.08+/-2.85 vs 0.30+/-0.43, p=0.000). Among 108 osseous metastatic lesions, 76 lesions showed as abnormal uptake on bone scan, and 76 lesions also showed as increased FDG uptake on PET/CT scan. There was good agreement between FDG uptake and abnormal bone scan finding (Kendall tau-b: 0.689, p=0.000). Lesion showed increased bone tracer uptake had higher SUVmax and SUVrel compared to lesion showed no abnormal bone scan finding (6.03+/-3.12 vs 1.09+/-1.49, p=0.000, 4.76+/-3.31 vs 1.29+/-0.92, p=0.000). The order of frequency of osseous metastatic site was vertebra, pelvis, rib, skull, sternum, scapula, femur, clavicle, and humerus. Metastatic lesion on skull had highest SUVmax and metastatic lesion on rib had highest SUVrel. Osteosclerotic metastatic lesion had lowest SUVmax and SUVrel. CONCLUSION: These results suggest that FDG-PET/CT is more sensitive to detect breast cancer patients with osseous metastasis. CT scan must be reviewed cautiously skeleton with bone window, because osteosclerotic metastatic lesion did not showed abnormal FDG accumulation frequently.

PURPOSE: To analysis the efficacy of MRI in assessing fracture configuration and frequency of associated soft tissue injuries in tibial plateau fractures. MATERIALS AND METHODS: In the plain films and MRI of 47 cases with tibial plateau fractures,every fracture was classified by findings on plain film and MRI respectively according to the Schatzker system and they were compared with each other. The degree of displacement and depression of the fracture fragments were measured on plain film and MRI. RESULTS: MRI was more accurate in determining the classification of the fracture and measuring the displacement and depression of fragments. Fracture classifications were changed in 12 cases. Especially in Schatzker VI cases, articular step off over 2 mm and articular fragments over 2X2 cm were revealed in detail by MRI. Evidence of internal derangement of the knee was found in 38 (80.8%) cases. CONCLUSION: Most of the cases with acute tibial plateau fracture were commonly associated with ligamentous and meniscal injuries. MRI can aid in accurate evaluation of tibial plateau fracture patterns and decision of treatment plan.

Mycosis fungoides(MF) is representative of cutaneous lymphoma and over many years progresses to plaques and tumors steadily. The extent and type of skin lesions at initial diagnosis and the presence of extracutaneous involvement are predictive indicators of survival in MF patients. Patients with limited plaque lesions are the least likely to have extracutaneous involvement and thus have the longest survival similar to the control population. We report a case of 45-year-old woman, who developed multiple subcutaneous nodules in normally appearing skin during photochemotherapy (PUVA). She had been treated with PUVA for the limited pre-mycotic skin lesions (T1 stage), which themselves showed good response to the treatment. She experienced the insidious course of early stage, but thereafter rapidly progressed to the tumor stage unusually during treatment.

An Insertion/deletion polymorphism in angiotensin converting enzyme gene has been considered the important regulator of ACE activity in plasma and tissue. The deletion allele of this gene is associated with higher ACE activity, which ultimately increased angiotensin II formation. It is possible that alteration of ACE polymorphism might be contribute to development of end stage renal disease and cardiovascular disease where RAS system is implicated in disease process. This study determined the distribution of ACE genotype in 122 end stage renal disease patients and in a group of 101 healthy controls. Also we evaluated the difference of allele frequency in the hemodialysis patients with or without cardiovascular disease. ACE genotype was determined by polymerase chain reaction technique from the PBMC leukocytes of the patients. The results were as follows; 1)Patients population consisted of 122 hemodialysis patients and male to female ratio was 66:56, mean age was 54.3+/-12.8 years old. Mean duration of dialysis treatment was 52.5+/-37.5 months and the underlying disease of ESRD were diabetic nephropathy in 78 cases, chronic glomerulonephritis in 29 cases, hypertension in 8 cases, other disease in 7 cases. 2)In the contol patients, male to female ratio was 52:49, mean age was 46.1+/-15.1 years old. The age and sex distribution between ESRD and control group was not significantly different. 3)Of the total hemodialysis patients, 26.2% showed the II genotype, 35.2% of ID genotype and 38.6% of DD genotype. In the contol group, the frequency of each genotype was 20.8% of II, 55.4% of ID and 23.8% of DD genotype. The frequency of DD genotype was significantly higher in ESRD group than control group(p<0.05). 4)In the ESRD patients, 72 patients(59%) had the LVH and 23 patients(18%) had the ischemic heart disease. The genotype distribution in ESRD patients according to the presence of LVH or ischemic heart disease did not show any significant difference. The frequency of each genotype in the patients with LVH showed 22.2%(II), 43.1%(ID), 34.7%(DD), and 32.8%(II), 37.5%(ID), 29.7%(DD) in the patients without LV et al.:Angiotensin Converting Enzyme Polymorphism in Patients with End Stage Renal Disease- H. In the aspect of ischemic heart disease, the frequency of ACE genotype was 27.3%(II), 45.5% (ID), 27.3%(DD) in the group of ischemic heart disease, compared with the ditribution of 31.5 %(II), 40%(ID), 32.6%(DD) in the patients without ischemic heart disease. From the above results, it was concluded that insertion/deletion polymorphism in angiotensin converting enzyme gene, especially DD genotype, may be important in the pathogenesis of progression to end stage renal disease. There was no significant difference in I/D polymorphism according to the presence or absence of cardiovascular complications

Renal transplantation has been adopted as the treatment of choices for most patients with a end stage renal disease. This is the presentation of our experience of renal transplantation at Hallym University Hospital. From March 1984 to July 1998, 207 cases of renal transplantations were performed, 15 cases out of which were lost during follow-up period and excluded from the study. The mean age of recipients was 37.1 years. The male to female ratio was 1.5:1. Eighty nine renal allografts (46.4%) were from living unrelated donors, 59 (30.7%) from living donors and 44 (22.9%) from cadaveric donors. As an immunosuppression theray, a triple regimen was used in 104 cases (54.2), a double regimen in 86 (44.8%) and a single regimen in one (0.5%). The overall rejection developed in 87 cases (45.3%). The rejection rate was 59.3% in renal allografts from living related donors, 37.1% from living unrelated donors and 43.2% from cadavaric donors. The OKT3 and the antilymphocyte globulin (ALG) were used for steroid resistent rejection in 8 and 2 cases, respectively. Post-transplant diabetes mellitus were noticed in 22 cases (11.5). The most common complication was infection (28.1%), and 11 recipeints (5.7%) died during follw-up period. Infection was the leading cause of mortality. The overall graft survival was 92.2% at 1 year span and 83.1% at 3 year span. The overall patient survival was 95.6% at 1 year span and 92.5% at 3 year span.

Forty-two preoperative CT scans with renal cell carcinoma were reviewed and compared with pathologic findings to evaluate the differential points between stage I and II. Regardless of whole body staging, perirenal fat infiltrations were seen in 9 cases and the other 33 cases showed no infiltration onto perirenal fat tissue. We retrospectively reviewed them by comparing tumor size and CT findings, following three view points, lobulating contour of tumor margin, thickening of Gerota's fascia and strands in perirenal fat tissue. The size of them was 2-15 cm, size of the stage I tumors was 2-15 cm and that of stage II was 6-15 cm. In stage I(n=33), 25 cases(76%) showed smooth margin, and the others(n=8) showed lobulating contours. Thickening of Gerota's fascia was observed in 7 cases(21%) and strands in perirenal fat tissue in 14(42%). Of these, only one positive finding was seen in 7 cases(21%), 2 findings in 6(18%), 3 findings in 3(9%) and nothing in 17cases(51%). In stage II(n=9), 3 cases(34%) showed smooth margin, and the others(n=6) showed lobulating contours. Thickening of Gerota's fascia were observed in 5 cases(55%) and strands in perirenal fat tissue in 9(100%). Of these, one finding was seen in 2 cases(22%), 2 findings in 3(33%), 3 findings in 4(44%). In conclusion, it is insufficient to evaluate the perirenal fat infiltration in renal cell carcinoma with only one positive finding of 3 view points; lobulation of tumor margin, thickening of Gerota's fascia, strands in perirenal fat tissue. But if all these findings are shown, it is helpful to determinate perirenal fat infiltration of renal cell carcinoma.

PURPOSE: To evaluate dynamic CT features and its clinical courses of eosinophilic hepatic abscess. MATERIALS AND METHODS: Two-phase dynamic CT findings and the clinical courses of 13 pathologically proven cases of eosinophilic abscess were reviewed. All patients showed peripheral eosinophilia, and diagnoses were confirmed by ultrasound-guided biopsy(n=9) or operation(n=4). In two of the four patients who underwent segmental hepatectomy, worms of the species Fasciola hepatica were detected. Follow-up CT scans after treatment with antibiotics or praziquantel were available in seven and eight patients, respectively. RESULT: All hepatic lesions were found ina subcapsular location or in contact with Glisson's capsule around the bile duct. Arterial-dominant phase CT(n=11)demonstrated clusters of ill-defined low density masses without rim enhancement. Late-phase CT(n=13) more clearly depicted clustering lesions with enhancing rims and diminution of the low-density area. Follow-up CT scans aftertreatment with antibiotics(n=7) showed no change in the lesions in three patients and slight shrinkage of the mainmass with additional new lesions in four. On CT scans of nine patients performad after praziquantel therapy, hepatic masses were seen in all patients to be very slightly smaller after improvement of peripheral hypereosinophilia. CONCLUSION: Two-phase dynamic CT features appear to be helpful for the diagnosis ofeosinophilic hepatic abscess in patients with peripheral eosinophilia. Parasitic infestation by Fasciola hepaticafor example, is the presumed cause of such abscesses, though further studies are required.
