  • Purpose : To quantify the movement of lung Parenchyma for ICRU 50 Planning Target Volume (PTV) delineation of the lung region. Materials and Method : Fluoroscopic observations and measurements are Performed on 10 patients with chest region cancer who have normal putmonary functions We have divided the lung region into 12 parts for the right lung, 10 parts for the left lung and four to five Points of lung parenchyma were selected for anatomical analysis Points, Fluoroscopic images are sent to a computer and then movements are measured. Results : Both lowe lobes showed the longest longitudinal movements because of breathing (average 14.1mm, maximum 22.1mm), while anteroposterior displacement showed the smallest value. Lateral movements of the lung parenchyma averaged 6.6mm, and the maximum value was 9.1mm, (both hilar regions showed maximum values because of cardiac motion) Conclusion : We could quantify the lung movements by measuring parenchyma displacements. The movements of both upper lobes were less than those of the middle and upper lobes in longitudinal and transverse movements. Optimal margins can be selected for PTV delineation using these results.

  • A 48-year old male patient visited our hospital with uncontrolled hypertension and pair of the left leg. CT angiography shows atherosclerotic occlusion of both renal artery orifices and the left common iliac artery. Despite of medical treatment for 2 months, the clinical condition of the patient worsened. We performed the surgical revascularization with both renal arteries and aorto-left femoral artery bypass with using an 8 mm artificial vascular graft. He lived well without hypertension with using only angiotensin receptor blocker and an anticoagulant for 10 postoperative months. Using surgical revascularization for renovascular hypertension has decreased due to the development of intervention technology and medication, but this surgery is indicated in cases of renovascular hypertension with extensive atherosclerotic lesions. We report here on a case of surgical revacularization for medically Intractable atherosclerotic renovascular hypertension together with left common iliac artery occlusion.

  • Background : According to the study in ICOPER (International Cooperative Pulmonary Embolism Registry), the overall mortality rate of acute pulmonary thromboembolism (APTE) at 3 months is 17.4%. According to the study for current status of APTE in Japan, the hospital mortality rate is 14%. Although the incidence and mortality rate of APTE has been increasing, patient characteristics, management strategies, and outcome of APTE in the Korean population have not yet been assessed in large series. We therefore performed the national survey for the current status of APTE in the Korean population. Methods : 808 registry patients with APTE were analyzed with respect to clinical characteristics, risk factors, diagnostic procedures, treatment, and clinical outcome. Results : Main risk factors were immobilization, recent major surgery, and cancer. Common symptoms were dyspnea and chest pain. Common signs were tachypnea and tachycardia. The majority of registry patients underwent lung perfusion scanning. Spiral CT was used in 309 patients(42.9%), and angiography in 48 patients(7.9%). Heparin was the most widely used treatment. On multivariate logistic regression analysis, onset in hospital (odds ratio 1.88, p=0.0385), lung cancer (odds ratio 9.20, p=0.0050), tachypnea (odds ratio 3.50, p=0.0001), shock (odds ratio 6.74, p=0.0001), and cyanosis (odds ratio 3.45, p=0.0153) were identified as significant prognostic factors. The overall mortality rate was 16.9% and mortality associated with APTE was 9.0%. Conclusions : The present registry demonstrated the clinical characteristics, diagnostic strategies, management and outcome of patient with APTE in Korea. The mortality rate was 9.0%, and the predictors of mortality were onset in hospital, lung cancer, tachypnea, shock, and cyanosis. These results may be important for risk stratification as well as for the identification of potential candidates for more aggressive treatment.

  • Endometriosis is defined as an extrauterine growth of endometrial tissue and it is primarily limited in the pelvis but it can also occur in the pleural cavity as well as pulmonary parenchyme. The diagnosis of pulmonary endometriosis is usually based on the clinical history of recurrent hemoptysis in association with menstrual cycle and by histopathologic confirmation of endometrial tissue in the lung parenchyme. Pulmonary endometriosis was first reported by Lattes in 1956. and dozens of cases have been reported so far. We experienced a case of 25 year old single woman with a history of hemoptysis in association with her menstruation. The bleeding focus was localized with chest CT scan and repeated fibrooptic bronchoscopy and basal segmentectomy of the right lower lobe was performed. The resected specimen shows endometrial stroma and glands of early proliferative phase with respiratory epithelium on the laterobasal bronchus. Her postoperative course was uneventful with no recurrence of hemoptysis during 6 months of follow-up in the outpatient clinic.

  • A 47-years-old woman presented with a 2-month history of a dry mouth and dry cough. The patient had been taking medication for Sj$\ddot{o}$gren's syndrome for approximately 7 years. The chest radiography showed multiple cystic lesions and a hazy density in both lower lung fields. The HRCT showed a diffuse ground glass like appearance and multiple variable sized cystic lesions in both lung fields. After medication, the symptoms were aggravated. Bronchoscopy was preformed with a transbronchial lung biopsy. The biopsies showed an infiltration of lymphocytes, neutrophils, monocytes and histiocytes through the interstitial space of the alveola and a widening of the alveolar septa. However, the histological findings of the cysts were not obtained. Sj$\ddot{o}$gren's syndrome is a slowly progressive inflammatory autoimmune disease, which is characterized by lymphocyte mediated destruction of the exocrine glands, with pulmonary involvement in approximately 19-65%, High-resolution CT is a sensitive technique for assessing the pulmonary involvement in patients with Sj$\ddot{o}$gren's syndrome. Although a lung biopsy is not always necessary for establishing a diagnosis of an interstitial lung disease in Sj$\ddot{o}$gren's syndrome. A lung biopsy may reveal a wide spectrum of changes ranging from a mild inflammatory response to end stage fibrosis with honeycombing. Because of the predominantly peribronchiolar inflammatory infiltration and inspissated secretions the cysts were suspected to have been formed by the ball-valve phenomen. However, no definite evidence was obtained.

  • A glomus tumor is composed of modified smooth muscle cells that are similar to those of the glomus body. Its occurrence in the trachea is quite rare. To our knowledge, only 20 cases of glomus tumor of the trachea have been reported worldwide and there has been only 1 case in Korea. We report one case of a 58-year-old man with dyspnea who had a glomus tumor in the upper trachea with a review of literatures. The chest CT scan and bronchoscopy demonstrated a 2.5 cm sized lobulated tumor at the posterior wall of the upper trachea. It had an elongated shape with a broad base and with a highly vascularity. A simple resection of 3 levels of the trachearing was with a tumor and end-to-end anastomosis performed. Microscopic and immunohistochemical staining of the tumor revealed the characteristics of a glomus tumor.

  • Angiosarcoma is a rare but highly malignant tumorthat usually arises in the scalp or face of elderly males. Distant metastases favor the lung, liver, lymph nodes and skin. Metastatic pulmonary angiosarcoma commonly takes the form of a nodule but can sometimes appear as a thin-walled cyst. We report a case of 65 years-old male with a spontaneous pneumothorax, who underwent excision and radiotherapy for an angiosarcoma of the scalp 2 years ago. A chest CT scan revealed multiple cysts in the lung. The video-assisted thoracoscopic lung biopsy demonstrated subpleural cysts without tumor cells. A skin biopsy of the scalp showed an angiosarcoma. This case was diagnosed as a recurrence of an angiosarcoma with a supposed lung metastasis. This case suggests that a spontaneous pneumothorax in elderly people may be secondary to a pulmonary metastasis from an angiosarcoma of the scalp.

  • Cryptococcosis is a systemic mycosis that most often involves the lungs and central nervous system and, less frequently, the skin, skeletal system, and prostate gland. Cryptococcus neoformans, the causative organism, is a yeastlike round or oval fungus, 4 to $6{\mu}m$ in diameter, which is surrounded by a polysaccharide capsule and reproduces by budding and found in soil and other environmental areas, especially those contaminated by pigeon droppings. Humans and animals acquire infection after inhalation of aerosolized spores. Condition or factors that predispose to cryptococcosis include corticosteroid therapy, lymphoreticular malignancies, HIV infection, and sarcoidosis etc. We discribed a case of cryptococcosis involving lung and CNS coincidently without specific underlying disease and the literature on subject were reviewed. A fifty-six year-old previously healthy female presented with headache of 3 months of duration. She had no history suggesting immunologic suppression and we could not find any abnormal laboratory findings including blood sugar, serum immunoglobulin and complement level, HIV antibody, and T cell subsets. Chest roentgenogram and CT scan showed a solitary soft tissue mass in LUL with distal pneumonitis. Brain MRI showed granulomatous lesion in cerebellum and parasagittal cortex of right frontal lobe. The diagnosis was made by bronchoscopic brushing cytology, transthoracic fine needle aspiration, and sputum KOH mount and culture. She was treated 6 weeks course of Amphotericin B and switched to oral fluconazole therapy for 3 months. Her symptoms and X-ray findings were improved gradually and she is now under regular clinical follow up.

  • Polymyositis (PM) is a inflammatory connective tissue disease involving predominantly skeletal muscles, characterized by symmetrical, proximal muscle weakness, inflammation, and frequently, degeneration. Interstitial lung disease in association with PM occurs in 5~10% of cases and carries an especially grave prognosis. Although the cause of lung involvement in PM is not known, the underlying pathologic process in the lung is an immune mediated inflammation of alveolar structures, alveolitis. It is of interest, therefore, that cyclophosphamide, an immune modulating agent, has been reported to be effective in the treatment of PM. We report a case of corticosteroid resistant PM associated with interstitial lung disease, successfully treated with cyclophosphamide. A 37-year-old female was presented with 8 months duration of cough, exertional dyspnea, and muscle weakness. She had typical symptoms, physical findings, and elevated muscle enzyme levels in serum with characteristic findings of muscle biopsy. She also had typical interstitial lung disease pattern on chest X-ray and high resolution CT with restrictive pattern on pulmonary function test. The findings of transbronchial lung biopsy was compatible with interstitial lung disease. She failed to respond to corticosteroid initially. Subsequently steroids and cyclophosphamide were given with excellent clinical improvement.
