Rhabdomyoma is the most common benign cardiac neoplasm in neonates. Most patients with rhabdomyoma experienced spontaneous regression. Yet some of them need surgical therapy because of hemodynamic problems of the heart such as arrhythmia, outflow tract obstruction and valvular dysfunction. We found multiple masses in both ventricles on the patient's fetal echocardiogram. Heart failure caused by severe left ventricular outflow tract obstruction quickly presented after birth. The mass interfering with the outflow tract was resected via the transaortic approach at the first day of birth. Postoperative echocardiography showed complete release of the outflow tract obstruction. He was discharged on the postoperative day 8. During the 3 years of follow up, we found that the sizes of the remnant masses had gradually decreased.

A 12-year-old female mixed breed dog receiving a progesterone drug was referred for evaluation of an abdominal mass. Abdominal radiography and ultrasonography revealed a swollen uterus and an associated mass. Serum chemistry revealed hyperglobulinemia consistent with acute inflammation based on the results of serum protein electrophoresis. Fine needle aspiration of the mass guided by ultrasonography was performed for cytological evaluation. The cytological impression was consistent with adenocarcinoma. Exploratory laparotomy identified a uterine body mass, which was surgically removed for histopathology. Histology of the mass identified a uterine adenocarcinoma. Immunochemistry using anti-estrogen and progesterone receptor antibodies was performed and neoplastic cells were negative to both antibodies while some normal elements were reactive to both of them. Computer tomography demonstrated evidence of metastatic disease in the lung one week after the surgery and the dog died about 40 days after surgery.

Thirteen year old boy who had been stabbed in his left chest by the knife was transferred to our department from a general hospital, because of the massive bleeding from the intercostal tube drainage. Chest X-ray showed homogeneous density in the left lung field. He was confused and his vital signs were unstable. He was moved into a operating room as soon as possible. After resuscitation, his lacerated left ventricle wound was sutured through median sternotomy. The interventricular shunt was detected with intraoperative transesophageal echocardiography. The traumatic ventricular septal defect was closed via left ventricle using Dacron patch. His postoperative course was uneventful, and he was discharged with small residual shunt.

Intracardiac hemangiomas are very rare primary cardiac tumor and there have been at least 37 reports of surgically resected cardiac hemangiomas. Most cardiac hemangiomas are asymptomatic. In symptomatic patients, symptoms are related to the location of tumor and outflow tract obstruction or obstruction of inferior and/or superior vena cava. Sudden death may occur due to conduction disturbances. The principle of treatment is surgical resection, and the prognosis is dependent upon the size, location and multiplicity of the tumor. A 40 year old man was admitted due to chest contusion and was found to have an intracardiac mass during echocardiographic examination. The mass was successfully removed and pathologic examination showed benign hemangioma. The patient was recovered uneventfully in postoperative period and was followed up for 1 year without evidence of recurrence.

A 43-year-old Korean woman with billary ascariasis accompanied by cholellthiasis is reported. Her chief complaints were abdominal pain, nausea, and vomiting. She had the past history of several attacks of abdominal pain in her childhood. ciliary stones were recovered from the left hepatic duct after cholecystectomy, which contained degenerated cuticle or body wall, and numerous eggs of Ascaris lumbriooides. It is strongly suggested that the ciliary stones were formed from the dead Ascmis worm(s). This is a rare case of biliary ascariasis during the recent 5 years in Korea.

PACS(Picture Archiving Communication System)를 바탕으로 하는 DICOM(Digital Imaging and Communications in Medicine)은 주요 의료영상장비들 사이에 데이터와 영상을 효율적으로 교환하고 전송할 수 있도록 마련한 표준안으로 현재 대부분의 최신형 의료영상장비(CT, MR, DSA, CR(Computed Radiology), 초음파검사, 핵의학검사, 내시경검사, 조직병리검사, 등)들은 의료 영상 분야의 국제 표준인 DICOM 표준방식에 의해 영상을 제공하고 있다. 최근 이러한 의료영상장비들은 독립적으로 사용하기보다는 의료수술 모니터링 장비 등의 비 의학영상장비와 서로 연계하여 사용하는 경우가 많아졌다. 그러나 이러한 의료수술 모니터링 장비들은 DICOM 표준 데이터를 고려하지 못하므로 PACS를 통한 데이터 연계에 어려움이 있다. 따라서 본 논문에서는 표준 DICOM 포맷과 의료수술 모니터링 장비의 데이터 구조를 분석하여 non-DICOM 의료수술 모니터링 장비의 PACS 연동을 위한 방안을 제안하였다.

A 6-month old girl who had pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals underwent one-stage complete repair with unifocalization through a bilateral thoracosternotomy(clamshell incision). There were no serious postoperative compli cations, and the postoperative echocardio-graphy showed no residual ventricular septal defect or significant pulmonary artery stenosis. In this condition, great surgical variability exists regarding the sources of pulmonary blood flow. Recent clinical work has focused on a one-stage complete repair. The potential advantages of the clamshell incision are apparent in terms of mediastinal approach, postoperative results, and safety.

Background: Radiofrequency obliteration and endovenous laser therapy of the greater saphenous vein have recently been introduced as alternative, minimally invasive techniques for the treatment of saphenous vein incompetence. The 7 Fr. VNUS $ClosureFAST^{(R)}$ radiofrequency obliteration system was introduced in Gwang-Ju Veterans hospital. The purpose of this study is to evaluate the efficacy and complications of radiofrequency obliteration using the 7 Fr. VNUS $ClosureFAST^{(R)}$ system. Material and Method: Between May 2, 2007 and May 31, 2008, we performed radiofrequency obliteration on 90 patients. The number of males was 67 and their mean age was $57.9{\pm}11.0$ (range: $23{\sim}78$) years old. The patients underwent follow up exams at 3 weeks after the procedures and then every 3 months. The effects of treatment and the complications were reviewed. Result: The postoperative complications were ecchymosis (94.4%), pain (27.8%), paresthesia (25.6%), bullous formation (8.9%), edema (6.7%) and phlebitis (2.2%). One patient showed good blood flow after 3 weeks and one patient showed good blood flow after 3 months. The one-year success rate of radiofrequency obliteration in varicose veins was 97.6%. Conclusion: Our data showed acceptable operative results and short-term clinical results for treating varicose veins with radio frequency obliteration. Long-term follow-up and comparison of radio frequency obliteration with high ligation and stripping, previous radiofrequency ablation and endovenous laser therapy are needed in the future.

Septic arthritis of the elbow is a rare, but serious disorder in neonates. However, neonates often present with few systemic signs other than irritability or poor feeding. When the clinical findings are minimal or absent, joint aspiration gives us helpful information in making a diagnosis. Although many clinicians rely on its result, we experienced a case of early clotted joint effusion, which resulted negative joint aspiration in a neonate with septic elbow arthritis. Ultrasonography helped us to make an early decision to perform surgical intervention as showing different echogenicity of intracapsular portion from generally presented in septic effusion. Presenting case shows that ultrasonography can be an excellent second step examination of neonatal elbow presenting atypical clinical findings of septic arthritis.

Pilomatricoma is a benign skin tumor that develops from hair matrix cells. It most commonly occurs in the head and neck, followed by the upper extremities. Accuracy of preoperative diagnosis was low in previous studies and excisional biopsy was even performed frequently without imaging studies. We report a case of pilomatricoma of the shoulder that was easily diagnosed by ultrasound including color Doppler, which is a more useful imaging modality than computed tomography or magnetic resonance imaging scans not only because of its cost effectiveness but also because of the precise information obtained from mass contents.
