Bronchial artery aneurysm (BAA) is a rare entity that requires early diagnosis and immediate treatment due to the possibility of a life-threatening massive hemorrhage through rupture. The standard treatment is a surgical resection of the aneurismal artery. However, various embolization techniques, including coil embolization, are currently used as the optimal treatment because they are less invasive. A 65-year-old woman was referred for the treatment of intermittent hemoptysis. A chest CT scan showed an approximately 2 cm sized vascular mass with strong contrast enhancement originating from the right bronchial artery on the bronchiectatic parenchyma. On the angiogram, the inferior portion of the bronchial artery with a hypertrophic aspect and a huge bronchial artery aneurysm was detected on the left side branch. The bronchial artery aneurysm was embolized successfully with coils at the proximal and distal portion of the aneurysm. After coil embolization, the selective bronchial angiogram confirmed complete occlusion. We report this case of a bronchial artery aneurysm that was treated successfully with coil embolization.

The vascular surgery is the field that has developed in early 20 century and is progressing nowadays. Recent advance in surgical technique accompanying with excellent medical diagnosis and treatment, prompt angiographic usage, development of variable prosthetic material, and concomitant use of anti-coagulant have made remarkable results of vascular surgery. 83 cases of vascular surgery have been performed at Thoracic and Cardiovascular Surgery Department of Pusan National Unversity Hosaital since 1971 till 1990, for 20 years and their results are followed. Patient ductus arteriosus and Buerger`s disease were omited in this study. 1. The age distribution shows that the fifth and sixth decades are most frequently affected and mean age was 56.1 years old. Male to female ratio is 1: 2.32. 2. Among the 83 cases of all, number of occlusive vascular disease is 46 and that of aneurysmal disease is 33. 3. In clinical manifestation, most common symptom of occlusive disease is pulselessness and pain was next. Mass sensation is most commonly complained by patients of aneurysmal disease. 4. CT scan was more important in diagnosis of aneurysmal diseases and angiogram was more commonly used in occlusive diseases. 5. The common site of arterial occlusion was common iliac artery, femoral artery, aortic bifurcation, and external iliac artery, as its frequency rate. The most commonly affecting portion of aortic aneurysm was abdminal aorta, and descending thoracic aorta and femoral artery were next 6. Preoperative associated diseases were atherosclerosis[41 cases], hypertension[21 cases], valvular heart disease[11 cases], and diabetes mellitus[9 cases], etc, 7. Operative methods in ocllusive diseases were thrombectomy[36.9%], endarterectomy [10.9%], and bypass graft insertion[52.7%]. Among the bypass graft, Y-graft was used in 7 case, straight graft was used in 17 cases, and saphenous venous graft was used in 2 cases. 8. Postoperative complications were developed in 17 cases, and morbidity rate was 36. 9. Eleven patient were died within 1 month after operation, so operative mortality rate was 13.3%. 10. Duration of patency was beteween 7 and 58 months[average 27.5 months] in occlusive diseases and their 5-year patency rate was 56.3%. Duration of patency of aneurysmal disease was 20 months in aveage and their 5-year patency rate was 51.3%. 11. Patients of eleven cases of occlusive disease and two cases of aneurysmal disease required reoperation for variable reason. 12. 35 cases of patient have used anticoagulants: coumadin, ticlid, and persanthin-ASA combination.

Thymoma is the most common primary tumor of anterior mediastinum, accounting for 20% to 30% of all mediastinal tumors. The recurrence rate after total resection of the thymoma ranges 8% to 18%. We reported one patient of recurrent malignant thymoma imaged with Tc-99m MIBI, Tc-99m Tetrofosmin and Tc-99m (V) DMSA. Early and delayed Tc-99m MIBI and Tc-99m Tetrofosmin scintigraphies showed an increased uptake in the mediastinal area. Also, Tc-99m (V) DMSA scintigraphy revealed an increased uptake tn the corresponding area. Coronal SPECT images of Tc-99m MIBI, Tc-99m Tetrofosmin and Tc-99m (V) DMSA revealed increased uptake of each radiopharmaceutical in the tumor lesion corresponding to the mediastinal lesion on the chest CT. However, the normal blood pool activities of the heart and great vessels of Tc-99m (V) DMSA obscured the recurrent malignant thymoma. Although Tc-99m (V) DMSA is a useful tumor seeking agent, we recommend Tc-99m MIBI and Tc-99m Tetrofosmin SPECT rather than Tc-99m (V) DMSA to detect primary and recurrent malignant thymoma.

Synovial Sarcoma is the fourth most common sarcoma, accounting for 8-10 % of all sarcomas. Synovial sarcoma is highly malignant tumor of mesenchymal origin but rarely occurres in head and neck area. Less than 100 cases of synovial sarcoma occurring in head and neck area have been reported all over the world. Pathologically, there is two type of synovial sarcoma: monophasic variant is composed of only one cell type and "classic" (biphasic) synovial sarcoma has two cellular component, a spindle cell(fibrosarcoma-like) component and a pseudoepithelioma component. Recommended treatment is wide resection with negative margins. The role of chemotherapy and radiation therapy is controversial. We experienced a 42-year-old male patient with slowly enlarging, deep seated mass on right cheek. In the first operation, we suggested that the mass maybe benign tumor. But, initial excisional biopsy specimen of the primary lesion was consistent with synovial sarcoma. The final diagnosis was monophasic synovial sarcoma which was composed of spindle cells. Radical resection was performed two months later because remnant tumor was found on follow up MRI. No further treatment was done. There were no recurrence or metastasis on follow up MRI, chest CT and whole body bone scan after 15 months. This is a report of a rare case of synovial sarcoma of the face with a literature review.

Poncet's disease is an aseptic polyarthritis developing in the presence of active Tuberculosis occurring elsewhere, and is not due to direct involvement of joints but to an immunological reaction to tuberculoprotein. We experienced a case of Poncet's disease accompanying erythema nodosum in a 55-year-old female patient with pulmonary tuberculosis. She had multiple tender erythematous nodules on both lower limbs for 3 months and a cough and sputum from one month ago. She felt severe pain in both knees and ankles with swelling one week before admission. Her chest X-ray, computed tomography (CT) scan and positive sputum AFB stain results revealed that she had active pulmonary tuberculosis accompanying erythema nodosum and aseptic polyarthritis. Her arthritis and erythema nodosum were dramatically improved within four weeks after anti-tuberculosis therapy. We report a case of Poncet's disease in pulmonary tuberculosis accompanying erythema nodosum.

A factor VII gene -401 G/A polymorphism was identified in a patient with a pulmonary embolism. The patient was a 71-year-old woman who presented with acute-onset dyspnea. A chest CT scan revealed a pulmonary embolism. Despite the administration of low-dose warfarin as anticoagulation therapy, there was an excessively prolonged prothrombin time (PT). The blood tests revealed lower factor VII activity than normal. Full factor VII gene sequencing revealed a G to A substitution at -401 in the promoter region. There were no other gene sequence anomalies. PCR-based analysis indicated lower factor VII gene expression in the patient than in a control subject. The data suggested the promoter polymorphism to be responsible for the lower transcription level. In conclusion, we encountered a case of Factor VII DNA polymorphism in a patient with a pulmonary embolism showing significantly reduced Factor VII activity.

Copper sulfate is a copper compound used widely in the chemical and agriculture industries. Most intoxication occurs in developing countries of Southeast Asia particularly India, but rarely occurs in Western countries. The early symptoms of intoxication are nausea, vomiting, diarrhea, and abdominal cramps, and the most distinguishable clue is bluish vomiting. The clinical signs of copper sulfate intoxication can vary according to the amount ingested. A 75-year old man came to our emergency room because he had taken approximately 250 ml copper sulfate per oral. His Glasgow Coma Scale (GCS) score was 14 and vital signs were blood pressure 173/111 mmHg, pulse rate 24 bpm, respiration rate 24 bpm, and body temperature $36.1^{\circ}$ .... Arterial blood gas analysis (ABGa) showed mild hypoxemia and just improved after 2 L/min oxygen supply via nasal cannula. Other laboratory tests and chest CT scan showed no clinical significance. Three hours later, the patient's mental status showed sudden deterioration (GCS 11), and ABGa showed hypercarbia. He was arrested and his spontaneous circulation returned after 8 minutes CPR. However, 22 minutes later, he was arrested again and returned after 3 minutes CPR. The family did not want additional resuscitation, so that he died 5 hours after ED visit. In my knowledge, early deaths are the consequence of shock, while late mortality is related to renal and hepatic failure. However, as this case shows, consideration of early definite airway preservation is reasonable in a case of supposed copper sulfate intoxication, because the patients can show rapid deterioration even when serious clinical manifestation are not presented initially.

We report a case of hepatopulmonary syndrome defined as a triad of chronic liver disease, increased alveolar oxygen gradient on room air, and intrapulmonary arteriovenous shunting. Chest rediographs showed bilateral, basilar, medium sized reticulonodular opacities. High resolution CT scand showed multiple centrilobular nodules and branching structures in the subpleural lung that suggested dilatation of lung vessels with abnormally large number of visible terminal branches. $^{99m}Tc$-macroaggregated albumin(MAA) perfusion lung scan showed right to left shunt. Contrast echocardiography demonstrated intrapulmonary vascular shunt without intracardiac shunt.

Tuberous sclerosis (TS) is an autosomal dominant disorder that is characterized by cutaneous lesions, seizures, mental retardation and hamartomas in various organs including the skin, kidney and brain. Pulmonary involvement is extremely rare, and occurs in approximately 0.1 to 1% of TS cases. Recent reports have indicated multiple micronodular pneumocyte hyperplasia (MMPH) as another rare form of pulmonary involvement of tuberous sclerosis. We report a case of a 35 year-old-male patient who had no pulmonary symptoms but showed multinodular pulmonary shadows on his chest CT scan. The patient was finally diagnosed with TS with MMPH of the lung. MMPH does not appear to have any malignant potential but the clinical significance of MMPH in TS patients is unknown.

Primary pulmonary amyloidosis is a rare condition that can be classified into the tracheobronchial, diffuse alveolar septal, and nodular parenchymal type. Tracheobronchial amyloidosis is characterized by deposition of fibrilar proteins in the tracheobronchial tree, and it can be subdivided into diffuse and focal varieties. In this report, a case of diffuse tracheobronchial amyloidosis confirmed by flexible fiberoptic bronchoscopic biopsy is presented. The patient was a 43-year old male with a chief complaint of cough and sputum for 20 days and dyspnea for one day. The chest CT scan showed diffusely thickened walls of both the main and lobar bronchi with calcification. The bronchoscopic findings showed nodular lesions of the trachea, a diffuse bronchial stenosis of both the main bronchi and a pinpoint narrowing of the left upper and right middle lobar bronchus. The biopsy showed submucosal deposits of homogenous eosinophilic amyloid materials and an apple-green birefringence under polarizing microscopy following the Congo-red stain.
