In Asia, mammography following the injection of foreign materials into the breasts for cosmetic augmentation is frequently seen and diagnosis based on the typical radiologic findings is straightforward. We report the unusual radiologic findings in two patients with foreign body granulomas caused by injected foreign materials and discovered incidentally during screening work up. The mammographic findings were bilateral, hyperdense, spiculated masses, with occasional microcalcification, and at sonography, markedly hypoechoic, spiculated solid masses, located near the pectoralis muscle and partly extending into it, were observed. These radiologic findings mimicked malignancy.

We have performed surgical procedure in 456 patients(582 lids) with blepharoptosis. The surgical results were studied retrospectively according to age, sex, etiology, surgical methods, surgical results, and postoperative complications. Of all patients, male accounted for 58.6% and monocular ptosis(72.4%) occurred more often in the right eye(37.5%) than in left eye and binocular ptosis was found in 126 cases(27.6%) and most of ptosis proved to be congenital(92.3%) in origin. The 3~4mm group(63.9%) was the highest in the amount of blepharoptosis and the function of levator was most common in less than 4mm group(69.0%). The surgical results on cosmesls were obtained successfully in 501 lids(86.1%). The postoperative complications were undercorrection(11.7%) that was most frequent, and followed by overcorrection(3.5%), exposure keratitis(3.3%), poor lid contour(2.6%), Infection(1.2%) and others(0.5%).

Purpose: To report a case of solitary fibrous tumor of the orbit in a patient with changes in tumor size and contrast enhancement.Case summary: A 64-year-old male patient presented with dizziness, discomfort on eye movement, anosmia, and proptosis. Orbital computed tomography showed an enhancing mass in the right extraconal space, lateral to the medial rectus and inferior to the superior oblique muscle. The mass appeared to be a cavernous hemangioma and the patient was monitored for changes in mass size and eye movements. After 24 months of follow-up, the mass size and symptoms of right eyelid swelling, proptosis, and diplopia had increased. Excision and biopsy of the mass were performed under general anesthesia. The biopsy confirmed that the mass was a solitary fibrous tumor. The postoperative period was uneventful and no recurrence was observed at 6 months after surgery. Conclusions Solitary fibrous tumor is a soft tissue tumor that rarely occurs in the orbit, and should be considered in cases with an intraorbital mass accompanied by increased size and changes in contrast enhancement on imaging.

Many risk factors for atherosclerosis have been proposed to identify high risk individuals. We conducted a retrospective study to determine the risk factors for development of carotid stenosis (CS) in Koreans. Database of 2,805 subjects who underwent a check up of carotid artery for health examination were analyzed. Stenosis (%) of common carotid artery or proximal internal carotid artery was examined with ultrasonography. Subjects were divided into 2 groups (Group I; CS <10%, Group II; CS > or =30%). We compared demographic, laboratory and clinical data between 2 groups to determine the risk factors of CS. One hundred ninety seven subjects (7.0%) were categorized as Group II. At age- and sex-adjusted multivariate analysis, diabetes mellitus, hypertension, cerebrovascular disease, ischemic heart disease, hyperlipidemia, aspirin medication, current smoking, fasting glucose, total cholesterol, low density lipoprotein-cholesterol (LDL-C) and leukocyte count were significant risk factors of CS. At stepwise logistic regression analysis, age, hypertension, hyperlipidemia, LDL-C and leukocyte count were independent risk factors. At subgroup analysis by smoking, age and leukocyte count were independent risk factors in smoker and age and hypertension in nonsmoker.

The recent development of laparoscopic cholecysteetomy has introduced the technique of laparoscopy to the general surgical operation. During this procedure, the deliberate pneumoperitoneum with carbon dioxide(CO2) insufflation in order to visualize better the abdominal viscera may causes some problems-hypercarbia, hypertension, pneumomediastinum, subcutaneous emphysema and cardiovascular impairment, We studied the changes of cardiovascular system and pulmonary gas exchanges clinically during general anesthesia for laparoscopic eholecystectomy in the 16 patients of Seoul National University Hospital. After induction of anesthsia, ventilation was controlled with tidal volume 10 ml/kg and respiration rate 10-15/min to maintain PaCO2 35 mmHg before insufflation of carbon dioxide. After measuring of control value of mean arterial pressure(MAP), heart rate(HR) and arterial blood gas analysis before insufflation of CO2, ventilation setting was not changed throughout the operation. MAP, HR, arterial blood gas analysis were measured at 30 min interval until the end of operation. The changes of MAP, HR and PaO2, throughout the operation are not statistically significant in comparison to control(preinsufflation) values. The PaCO2 was increased significantly by 8-10 mmHg in comparison to control values(p-value<0.01). In conclusion, minute ventilation should be corrected during general anesthesia for laparoscapic cholecysteetomy with CO2 insufflation according to continuous monitoring of end tidal CO2 and arterial carbon dioxide tension.

PURPOSE: To evaluate the clinical and radiographic findings of localized foreign body (FB) granulomas onmammograms. MATERIALS AND METHODS: This study involved 13 patients with localized FB granulomas on mammograms;their history of mammoplasty or other plastic procedures was obtained by telephone interviews. Two radiologistsanalyzed the location and morphology of FB granulomas and the presence of associated linear densities orparenchymal distortion on mammograms. Four patients underwent ultrasonography. RESULTS: No patient had a historyof mammoplasty. All 13, however, had a history of plastic procedure, three to 22 (average, 12) years previously,as follows : foreign materials including silicone liquid and oil such as paraffin been injected into the anteriorneck area of nine patients, the infra-auricular area of two, and the nose of two. Multiple small, high-density,flocculent nodules representing FB granulomas were distributed bilaterally in nine patients; they were noted inthe upper inner portion of 11 of 26 breasts. In eight patients, mammograms showed linear opacities suggestingfibrosis. There was no calcification or parenchymal distortion. Though in three cases, the masses were palpable.Ultrasonography revealed several anechoic nodules with posterior enhancement in subcutaneous fatty layers, and inone, 0.2cc of oil droplet had been aspirated under ultrasonographic guidance. CONCLUSION: Localized FB granulomasof the breast could be caused by the migration of FB from cervicofacial areas. Mammography showed characteristicdistribution of upper inner portions, and the findings were similar to those of mild interstitial mammoplasty.

BACKGROUND: We observed several cases of rare vascular anomalies within the femoral triangle during varicose vein operations. METHODS: From among 2,093 patients who underwent stripping operations of the great saphenous vein between January 2002 and June 2016, 14 cases of rare vascular anomalies were enrolled in this study. RESULTS: Twelve cases of femoral artery and vein transposition (0.57%), 1 case of separate entrance of the great saphenous vein trunk and its tributaries (0.05%), and 1 case of separate entrance with femoral artery and vein transposition (0.05%) were observed. The preoperative diagnosis rate was 71% (10 of 14) using duplex ultrasound. In all cases of femoral artery and vein transposition, the saphenofemoral junction was located at the lateral or posterolateral side of the superficial femoral artery, corresponding to complete or incomplete transposition, respectively. Among the 12 cases of femoral artery and vein transposition, 5 cases were complete transposition and 7 cases were incomplete transposition. In 2 cases of separate entrance of the great saphenous vein trunk and its tributaries, the separated tributaries formed a common trunk before connecting to the femoral vein. CONCLUSION: The anatomy of the saphenofemoral junction may infrequently be altered in some individuals. Detailed preoperative sonographic examinations and meticulous groin dissection during the operation are necessary to prepare for unexpected anatomical variations.

The transplantation of a large number of hair graft has become an important method in hair restoration surgery and reconstruction of pubic hair and eyebrows. Between September 1996 and December 1998, single hair graft using Choi hair transplanter was performed for 22 patients with male pattern baldness, 8 patients with alopecia of pubis, 6 patients with alopecia of eyebrows ranging from 20 to 59 years of age. Usually between 1000 and 1500 single hair grafts per session are performed on male pattern baldness, between 350 and 500 grafts on alopecia of pubis, between 150 and 250 grafts on alopecia of eyebrows. All procedures were done under intravenous sedation and local anesthesia. A donor horizontal ellipse of scalp is harvested from the occipital area. Questionaires regarding cosmetic satisfaction, side effects and general efficacy of hair transplantation were recorded by patients themselves one year after surgery. The procedure has been proved to be safe and patients can expect aesthetically satisfactory results. No serious complications were reported The complications including facial edema, temporary sensory change on the donor site, and folliculitis were observed and resolved spontaneously. The use of single hair graft using Choi hair transplanter for the correction of male pattern baldness, alopecia of pubis and alopecia of eyebrows has been proven as one of the safe and effective method in obtaining excellent results.

BACKGROUND: Verrucous hemangioma (VH) and angiokeratoma (AK) are vascular birthmarks of an unclear nosology and these birthmarks commonly show a superficial hyperkeratotic vascular component. There are both similarilities and differences between VH and AK with some confusion concerning their overlapping features. OBJECTIVE: This study was undertaken to review the clinicopathological features of VHs and AKs and to determine the similarilities and differences between them. METHODS:We retrospectively reviewed 11 VHs and 7 AKs at the Vascular Anomaly Clinic of our hospital over the past 10 years. They were evaluated from the clinicopathologic point of view for factors such as the age of onset, location, size, symptoms, the histopathological epithelial change and involvement of deeper tissue. RESULTS: These birthmarks share common clinical features with the exception of gender and lesion size. Histopathologically, hyperkeratosis, acanthosis and capillary dilatation in the upper dermis were commonly seen. Yet lobular proliferation and dilatation of blood vessels in the deep dermis, or more importantly, the subcutis were detected in VH only. Furthermore there was a case of VH that showed diffusely scattered increased blood vessels in the subcutis, suggesting an evolving stage of VH and there was another case of VH that was erroneously diagnosed as AK via the initial biopsy, and the final diagnosis was changed according to the excised lesion. CONCLUSION:The two diseases share most of their clinicopathological features, but small parts of features like gender, the clinical size and the histological deep dermis/subcutis involvement were differences. Making the correct differential diagnosis between VH and AK through a deep biopsy with appropriate timing and long-term follow-up and/or radiological examination is helpful to avoid erroneous management.

PURPOSE: The diagnosis of acute cholecystitis is usually made by performing ultrasonography or biliary scintigraphy. We have introduced the (99m)Tc-ciprofloxacin (infecton) scan for diagnosing of acute cholecystitis. The main aim of this study was to evaluate the efficacy of (99m)Tc-ciprofloxacin imaging in comparison with ultrasonographic findings for the diagnosis of acute cholecystitis. METHODS: Sixteen patients who were thought to have acute or chronic cholecystitis, based on the clinical and sonographic findings, were included in this study. We gave intravenous (99m)Tc-ciprofloxacin to sixteen patients and we obtained the SPECT images after one hour. The final diagnosis of acute cholecystitis was made according to the pathologic reports. RESULTS: According to pathologic reports, out of the sixteen patients, twelve patients had acute cholecystitis and four patients had chronic cholecystitis. On the (99m)Tc-ciprofloxacin scans, twelve patients had positive images showing acute cholecystitis on account of the hot uptake in the gallbladder and four patents had negative images showing chronic cholecystitis due to the negative uptake in the gallbladder. Among them, one false positive case and one false negative case were observed. With performing ultrasonography, twelve and four patients were diagnosed as having acute and chronic cholecystitis respectively. Out of them one false positive case and three false negative cases were observed. Based on the pathologic reports, (99m)Tc-ciprofloxacin imaging has a sensitivity of 91.7% and a specificity of 75%. The ultrasonography had a sensitivity of 91.7% and a specificity of 25%. CONCLUSION: As a result of comparing the sensitivity and specificity of the (99m)Tc-ciprofloxacin scan with those of the ultrasonography, the (99m)Tc-ciprofloxacin scan is considered to be useful test method to diagnose acute cholecystitis.
