We report a case of angiosarcoma of the jejunum in a 65-year-old female. This angiosarcoma developed 20 years after postoperative irradiation for cervical carcinoma of the uterus. Grossly, the resected jejunum showed a 8 cm long segmental hemorrhagic lesion with multiple, small hemorrhagic nodules or cysts on its serosa and mesentery. Microscopically, the wall of jejunum was infiltrated by epithelioid or polygonal tumor cells arranged in solid nests or lining irregular vascular spaces. The case is of interest that the tumor occurred in the very unusal site for angiosarcoma and the patient had a past history of irradiation for uterine cervical carcinoma 20 years ago. In addition, the resected intestine showed histologic changes of chronic irradiation effect. Therefore, this case supports the view that there is cause and effect relationship between irradiation adn angiosarcoma.

Brenner tumors constitute about l.5~2.5% of all primary ovarian neoplasms and are almost always benign. It appears to derive from the surface epithelium of the ovary which undergoes metap1asia to form the urothelial-like components. we experienced a case of malignant Brenner tumor with adenocarcinoma and squamous cell carcinoma patterns in a 57-year-old woman. It was partly cystic tumor and contained a 4cm-sized gray yellow, lobulated or papillary solid mass, projecting from the cystic wall. Ultrastructurally, the solid mass was composed of malignant urothelial-like cells with focal glandular differentiation.

PURPOSE: We performed this study to describe the findings of MR Myelography(MRM) of herniated disc disease, spinal stenosis and spinal tumor and to evaluate the usefulness of the MRM in comparison to MRI. MATERIALS AND METHODS: MRI and MRM were performed in 31 patients with herniated disc disease(12 patients), spinal stenosis(11 patients) and spinal tumor(8 patients). MRI and MRM were done with 1.5-T Signa MR, using fat suppressed heavily T2-weighted fast spin echo technique. We retrospectively analyzed MRM images about the thecal sac indentation, compression or displacement of the nerve root, extent and degree of narrowing of spinal canal, relationship between spinal tumor and spinal cord. MRM findings were compared with MRI in all cases. RESULTS: In 18 herniated disc cases of 12 patients, focal filling defect with cutoff or displacement of the nerve root in eight cases of paracentral herniated disc was seen. Cutoff and displacement of the nerve root were more clearly delineated on MRM than rvlRI. In the patients of spinal stenosis(11 cases), hourglass deformity of the thecal sac or complete spinal block of the subarachnoid space was clearly demonstrated. The extent and severity of spinal stenosis were more accurately evaluated on MRM than MRI. MRM finding of intramedullary tumor(3 cases) was enlargement of spinal cord. Five cases of intradural extramedullary tumor showed intradural filling defect, which caused contralateral displacement of the spinal cord with meniscus sign on inferior margin of the mass. CONCLUSION: MRM shows characteristic findings of herniated disc disease, spinal stenosis and spinal tumor. MRM yields excellent definition of the thecal sac, nerve roots and nerve root sleeves in relation to herniated disc and may be more accurate in evaluation of the degree and extent of spinal stenosis than MRI.

BACKGROUND: Metabolic syndrome (MetS) is constellation of cardiovascular risk factors. There are three typically used definitions of MetS proposed by WHO, IDF and NCEP-ATP III. We conducted this study to compare the associations of MetS by WHO, IDF and NCEP-ATP III definition to various metabolic markers of coronary heart diseases in Korean type 2 diabetes patients. METHODS: We enrolled 151 Korean type 2 diabetes patients in one hospital. Anthropometric and biochemical parameters, including high-sensitivity C-reactive protein (hsCRP), homocysteine, uric acid were measured. And then, we divided MetS group from non-MetS group according to three other definitions. RESULTS: Serum hsCRP level was higher in those with MetS group than non-MetS group by WHO definition (0.33 +/- 0.36 mg/dL vs 0.18 +/- 0.26 mg/dL, P < 0.001). But, there are no difference in MetS group and non-MetS group by IDF and NCEP-ATPIII definition. (By IDF, 0.28 +/- 0.31 mg/dL vs 0.25 +/- 0.34 mg/dL, P = 0.64; By NCEP-ATP III, 0.28 +/- 0.33 mg/dL vs 0.22 +/- 0.32 mg/dL, P = 0.41). Uric acid and homocysteine levels were higher in those with MetS by WHO definition (P < 0.05). Similarly, analyses according to IDF and NCEP ATP III definition showed no significant difference. CONCLUSION: In conclusion, WHO definition of MetS has a stronger relationship with the biochemical markers of coronary heart disease in Korean type 2 diabetes patients.

Hormone replacement therapy combined with progestogens induces changes in effect of estrogen on serum lipid levels and it has been known that the changes depend on a type and dosage of progestogen. It is also known that progestational agent induces positive ch-ange in bone mineral density. To study the effects of progestogen on lipoprotein and bone metabolism, we administ- ered conjugated equine estrogen 0.625 mg alone to 50 postmenopausal women, in combinat- ion with medroxy- progesterone acetate 5 mg to 40 postmenopausal women. The data demonstrated a beneficial effect in lipoprotein profiles in both groups. Total cholesterol in two groups decreased from the baseline values, LDL-cholesterol decreased significantly by 4.8 % in group I and 16.2 % in group II(p < 0.05), HDL-cholesterol increa- sed significantly by 11.3 % in group I and 14.7 % in group II(p < 0.05), triglyceride incre- ased slightly in both groups. Bone mineral density of femur was maintained and BMD of vertebrae increased by 1.1 % in group I and 2.0 % in group II, but it is not statistically significant. The differences of changes between two groups were not statistically significa- nt. Our results suggest that medroxyprogesterone acetate have no adverse effect on HDL -cholesterol and have no additive effect on bone mineral density in hormone replacement therapy.

Well differentiated osteosarcomas are variants of osteosarcoma composed mainly of fibrous and osseous tissue with minimal cystologic atypia. This tumor may be misinterpretated as a benign lesion if the radiologic and clinical features are not taken into account. We report a typical case of intraosseous well differentiated osteosarcoma occuring in the left distal femur of a 58-year-old woman. Radiologically, it appered as an ill-defined lesion with a mixture of sclerotic and osteolytic ares. But there was a lack of highly destructive appearance of conventional osteosarcoma. Grossly, the mass occupied a metaphysis of the distal femur with extension into the diaphysis and epiphysis. Multifocal cortical destruction and sclerosis were also associated. Histologically, the mass showed typical features of intraosseous well differentiated osteosarcoma. There were various patterns of osteoid deposits and bone formation mimicking those of fibrous dysplasia, nonossifying fibroma or parosteal osteosarcoma.

The pattern of thickening of the extrahepatic bile duct on computed tomography was analysed in 30 cases with recurrent pyogenic cholangitis diagnosed by surgery (n=19) or clinical basis (n=11). The mean wall thickness of the extrahepatic bile duct was 3.3mm (range, 1-6.3mm). Diffuse thickening of the extrahepatic bile ductal wall was demonstrated in 26 of 30 cases. Diffuse thickening of the extrahepatic bile duct in recurrent pyogenic cholangitis may be differentiated from focal thickening of duct in a common duct cancer or pancreatic cancer.

We describe a case of cavitary metastasis to the lungs from a small angiosarcoma of the scalp, in which themetastatic lesions were complicated by pneumothorax and pulmonary hemorrhage. On high-resolution CT, the lesionssimulated the findings of Langerhans cell histiocytosis. Thin-walled cavitary metastatic lesions were similar tothose of thin walled air cysts in Langerhans cell histiocytosis. Ground-glass opacity simulated the findings ofsmoke r's respiratory bronchiolitis in Langerhans cell histio-cytosis but histologically represented hemorrhageduring metastasis of the angiosarcoma.
