We report a 35-year old female patient with history of seizure and mass which was confirmed as a plasma cell granuloma, arising in the left parietal area. The mass appeared on magnetic resonance imaging as well circumscribed area of decreased signal that markedly enhanced with administration of the contrast. Pathologically, biopsy showed a mixed cellular population with considerable numbers of plasma cells along with eosinophils and lymphocytes and the tumors was characterized immunohistochemically by polyclonal population of lymphoid cells.

We report a case of embryonal cell carcinoma originating in the spermatic cord with review of literature. To our knowledge, this is the first case to be reported in Korea.

Multiple intracranial tumors of different cell types are rare. We report a case of double primary intracranial tumors of different histologic types: oligodendroglioma, and pituitary adenoma. Von Recklinghausen's disease or other etiologic factors supposedly associated with multiple brain tumors were not recognized in this 36-year-old male patient.

OBJECTIVE: This study was undertaken to demonstrate the usefulness of endovascular technique in treatment of vertebral artery dissecting aneurysms. METHODS: The clinical characteristics of vertebral artery dissecting aneurysms were reviewed in 11 patients with particular focus on clinical presentation, angiographic feature and outcome. RESULTS: All patients underwent the GDC embolization. One of them was managed with surgical trapping after failure of GDC embolization and the other with GDC embolization after failure of stent insertion. Nine patients were recovered with intact neurological feature, one patient died as result of sepsis and ARDS, and one patient was suffered from cerebellar infarction. CONCLUSION: Although the timing of the procedure and site of occlusion remain controversial, proximal GDC occlusion of vertebral artery appears to be a safe and effective therapy for patients with vertebral artery dissecting aneurysm. This procedure provides an important, less invasive alternative for this condition.

PURPOSE: The detection of bladder cancers by noninvasive techniques remains an unsolved problem. We evaluate the availability of an immunoassay for urinary nuclear matrix protein, NMP 22, as an indicator for transitional cell carcinoma of the bladder. MATERIALS AND METHODS: Three groups of subjects participated in this trial of NMP 22: 22 patients with transitional cell carcinoma (group 1), 12 patients with urinary tract infection (group 2) and 31 healthy volunteers (group 3). NMP 22 was determined by ELISA using a commercial test kit (NMP 22 Test Kit, Matritech Inc., USA), We compared urinary NMP 22 levels to the grade, stage, cytology and DNA flowcytometry of transitional cell carcinoma of bladder. RESULTS: NMP 22 values in these 3 groups were significantly different (group 1, median 24.81 U/mL; group 2, median 8.41 U/mL; and group 3, median 5.12 U/mL; Mann-Whitney U test for differences between 3 medians, p < 0.05). The patients with transitional cell carcinoma had significantly greater urinary NMP 22 levels than those with no evidence of tumor (Mann-Whitney U test for differences between 2 medians, p<0.01). There was no zelationship between the urinary NMP 22 levels and tumor grade, stage, cytology or DNA flowcytometry. CONCLUSIONS: It is possible that urinary NMP 22 could improve the detection of bladder transitional cell carcinoma.

PURPOSE: The purpose of this study was to evaluate the efficacy of contrast-enhanced MR angiography for follow-up examinations after metallic stent placement and to examine the effects of change of imaging parameters used for contrast-enhanced MR angiography. MATERIALS AND METHODS: After four metallic stents (Passager, Ninitol, Wallstent, and Memotherm) were placed in an abdominal aorta shaped vascular phantom, efGRE (enhanced fast gradient recalled echo) 3-D MR angiography was performed, using a 1.5T unit. The four metallic stents were graded 1-3 according to the width and length of their high signal intensity. Variations in the degree of high signal intensity were evaluated according to imaging parameters. RESULTS: The width and length of high signal intensity with the Passager stent and Nitinol stent were greater than with the Wallstent and Memotherm. The larger the field of view, the smaller the matrix number, the larger the flip angle, the greater the width and length of high signal intensity in the metallic stent. CONCLUSION: Contrast-enhanced MR angiography may be a useful follow-up procedure after the placement of Passager and Ninitol metallic stents. The signal intensity of stent lumen varies according to imaging parameters, and the selection of optimal parameters is therefore important.
