Hemangioma is the most common soft tissue tumor in the body. Though it may occur anywhere in the body, hemangioma of the uterus is a very rare tumor. Hemangioma is almost asymptomatic, but it is sometimes clinically important because it can cause massive hemorrhage and this is a life-threatening condition. We report here on the magnetic resonance imaging and pathologic findings of cavernous hemangioma of the uterus in a 32-year-woman with menorrhagia.

PURPOSE: The purpose of this study was to evaluate the MR findings of calvarial eosinophilic granuloma. MATERIALS AND METHODS: We reviewed the MR imaging studies of nine patients [M:F=3:6, aged 6 -35 (mean, 20.5) years] with pathologically proven eosinophilic granuloma in the calvaria. The findings were evaluated for involvement of the diploic space, changes in adjacent bone marrow, distinction of the transitional zone, pattern of bone destruction, signal intensity and contrast enhancement of the tumor, and contrast enhancement of the adjacent dura. RESULTS: All lesions involved the diploic space, showed no change in adjacent bone marrow, and had a distinct transitional zone. In most (8/9) cases there was asymmetric bony destruction. On T1-weighted images, signal intensities of the tumors varied, while on T2-weighted images, hyperintensity was observed in seven cases, isointensity in one, and hypointensity in one. After the administration of contrast material, enhancement was homogeneous in four cases and inhomogeneous in five. Enhancement of the adjacent dura was demonstrated in all nine cases. CONCLUSION: The characteristic MR findings of calvarial eosinophilic granuloma are variable signal intensity on T1WI, high signal intensity on T2WI, and marked contrast enhancement; in addition, there is a distinct transitional zone, asymmetrical bony destruction, and associated dural enhancement.

High flow priapism is a prolonged, non-painful penile erection unrelated to sexual stimulation after penile or perineal trauma. We report a case of high-flow priapism treated successfully with superselective embolization. An 8-year-old boy presented to our hospital 9 days after having been struck in the perineum during a bicycle accident. After the injury, the patient suffered a painless prolonged erection. High flow priapism was diagnosed by cavernosal blood gas analysis and penile duplex doppler ultrasonography. We identified the position of the fistula and pseudoaneurysm with angiography and embolized the lesions super-selectively with an autologous blood clot, gel foam, and a microcoil, bilaterally. After 2 superselective embolizations, the patient had detumescence. This case shows that bilateral arterio-cavernosal fistulas can be successfully treated with superselective arterial embolization.

PURPOSE: An experimental study was carried out to evaluate the morphological changes in the blood brain barrier and neighbouring brain tissue caused by Gd-DTPA in uremia-induced rabbits. MATERIALS AND METHODS: Bilateral renal arteries and veins of ten rabbits were ligated. Gd-DTPA(0.2 mmol/kg) was intravenously injectedinto seven rabbits immediately after ligation. After MRI, they were sacrificed 2 or 3 days after ligation in orderto observe light and electron microscopic changes in the blood brain barrier and brain tissue. RESULTS: MRIfindings were normal, except for enhancement of the superior and inferior sagittal sinuses on T1 weighted imagesin uremia-induced rabbits injected with Gd-DTPA. On light microscopic examination, these rabbits showed perivascular edema and glial fibrillary acidic protein expression ; electron microscopic examination showed separation of tight junctions of endothelial cells, duplication/rarefaction of basal lamina, increased lysosomes of neurons with neuronal death, demyelination of myelin, and extravasation of red blood cells. Uremia-induced rabbits injected with Gd-DTPA showed more severe changes than those without Gd-DTPA injection. CONCLUSION: Injuries to the blood brain barrier and neighbouring brain tissue were aggravated by Gd-DTPA administration inuremia-induced rabbits. These findings appear to be associated with the neurotoxicity of Gd-DTPA.

PURPOSE: Advanced techniques now make it possible to remove considerable amounts of subcutaneous adipose tissue more safely with minimum blood loss. However, few have analyzed the metabolic consequences of liposuction. The purpose of this study was to identify the early effects of the surgical removal of subcutaneous fat on metabolic changes in patients who have undergone liposuction. METHODS: Nineteen patients were evaluated from June 2005 to December 2005. Preoperative body weight, serums levels of lipids, apolipoprotein A1, dehydroepiandrosterone(DHEA), uric acid, insulin, and glucose were evaluated. Insulin resistance was determined using the homeostasis model assessment of insulin resistance (HOMA-IR), which is based on fasting glucose and insulin concentrations. All of these data were remeasured in 1 and 4 weeks postoperatively. Tumescent fluid was infiltrated using the superwet technique. The liposuction device used was a Liposlim(R) power-assisted unit. RESULTS: Average volumes of infiltrate and aspirate were 3,268mL and 2,892mL, respectively. Results in 1 week postoperatively demonstrated a significant difference in high-density lipoprotein(HDL) cholesterol, apolipoprotein A1, insulin, and HOMA-IR levels. However, all values were within normal limits and returned to baseline in 4 weeks postoperatively. CONCLUSION: This study provides little to support the presumed therapeutic effect of liposuction. And, it is unclear whether liposuction can prevent or be used to treat the metabolic complications of obesity. However, the results of the present study lead us to believe that liposuction is a metabolically safe procedure.

To estimate the incidence rate of coronary heart disease in Korea, of all residents of the Taegu city aged 25 or above, those who had an acute MI or fatal coronary event between 1 July 1996 and 30 June 1997 were registered. Seven hundreds and eight patients were registered during the study period(685 were identified at hospital and 23 were autopsy cases). Age-standardized annual incidence rate of men in city area was 93 per 100,000(95% CI; 61-142) and 33(95% CI; 16-67) in women(100 in men and 20 in women aged 35-64). The incidence was rapidly increased after age 40 in men, however, in women after age 60. Twenty-eight-days case fatality rate was 45% in men and 47% in women. However, in the age group of 45-59 case fatality rate in women was two times higher than that in men. In conclusion, crude annual incidence rate of CHD in city area was 73 per 100,000 in men and 33 in women. The age-standardized annual incidence of CHD in men(93 per 100,000) was 3.2 times higher than that in women (33 per 100,000) in Korea.

PURPOSE: To evaluate the different angio-architectures of brain arteriovenour malformatigns (AVMs) accordingto the presence of non-hemorrhagic symptoms or intracerebral (ICH) and/or intraventricular hemorrhage(IVH). MATERIALS AND METHODS: The results of complete cerebral angiography obtained in 215 patients with AVM between1989 and 1994 were retrospectively reviewed. The M:F ratio was 136:78 and their mean age was 29 (ranged 4 - 66)years. On the based of clincal presentation, CT and/or MR images, they were divided into hemorrhagic andnon-hemorrhagic groups. Angiograms were analyzed by two radiologists for the size and location of nidus; thenumber of feeding arteries and the extent of aneurysm, stenosis, dural supply, and angiomatous change; the numberof draining veins and the extent of deep or superficial drainage, stenosis, ectasia, kinking, and stasis. Thestandard chi-square test was used for statistical analysis. RESULTS: Hemorrhage was noted in 140 patients(65%),and no hemorrhage in 75(35%). Hemorrhage was more common in AVM with deep-seated and callosal locations, a nidusof less than 2cm, single feeder and single venous drainage, and deep venous drainage only (p < 0.05 - 0.001).Non-hemorrhagic presentations were more common in AVM with cortical and subcortical location, a nidus of more than5cm, angiomatous change, dural supply, both superficial and deep venous drainage, kinking, and stasis (p <0.05-0.001). CONCLUSION: The angio-architechture of AVM with hemorrhage correlated with clinical symptomaticpresentation. Analysis of the patterns of angioarchitectureis useful for prognosis and in deeiding the direetionof freatment.

OBJECTIVES: This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). METHODS: Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November 30, 2001. RESULTS: Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major depressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. CONCLUSION: The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.
