Systemic lupus erythematosus frequently has thoracic involvement among connective tissue diseases. One of the pleuropulmonary manifestations is diffuse interstitial lung disease including nonspecific interstitial pneumonia(NSIP). NSIP is a newly classified disease among interstitial lung diseases. Systemic lupus erythematosus has a better prognosis than usual interstitial peumonia(UIP) and responds well to steroids. In this report, a 34 year-old woman who complained of a dry cough, and exertional dyspnea for 2 months is described. The chest X-ray showed fine reticular opacities and a mild honeycomb appearance in both basal lungs. High resolution computed tomography(HRCT) showed bilateral patchy areas of ground-glass attenuation and a mild honeycomb appearance in the subpleural of both the lower and the middle portion of the lung fields. An open lung biopsy showed prominent lymphocytic interstitial inflammation and fibrosis with small areas with a honeycomb appearance. This case was diagnosed as NSIP associated with systemic lupus erythematosus and was managed with oral steroids. Here we report a case of nonspecific interstitial pneumonia associated with systemic lupus erythematosus confirmed by HRCT and an open lung biopsy with a review of the relevant literature.

We experienced a case of pulmonary cryptococcosis in an immunocompetent patient who presented with uncommon radiological findings. He complained of a dry cough for 3 weeks. The chest X-ray and CT showed multiple, variable sized, and irregular patch consolidations with cavities combined with some ground glass opacities in both lower lung fields. The diagnosis was made histologically via a thoracoscopic lung biopsy. The patient was administered oral fluconazole has since been well.

The incidence of appendiceal metastatic cancer is quite low. In particular, in small cell lung cancer, there is a very low incidence of a metastasis to the appendix. A 75-years old man with right lower quadrant pain, cough and sputum was transferred to our hospital. Abdominal CT revealed acute appendicitis with a perforation. The patient underwent surgery. The frozen sections of the tissue obtained during surgery, indicated a malignancy, but a right hemicolectomy was not performed due to the patient's poor general condition. The histology findings of the appendix were identified as a small cell carcinoma. The abdominal CT scan and chest x-ray at admission day showed a mass in the right lower lobe, and a further evaluation of the lesion was performed including positron emission tomography and flexible bronchoscopy with a biopsy. The pathology findings of the lung mass were also small cell lung cancer. The specimens from both sites stained positive for cytokeratin, cluster designation 56, synaptophysin, chromogranin-A and thyroid transcription factor 1. It was concluded that the appendiceal small cell cancer originated from the lung.

Silicone fluid is a biomaterial widely used in modern cosmetic procedures because there are few side effects, considerable chemical stability and predictable physical properties. However, many local and systemic adverse reactions have reported. In particular some serious pulmonary complications have been reported such as pulmonary thromboembolism, acute respiratory distress syndrome with some cases leading to mortality. Most of the serious complicated cases were induced by an illegal silicone fluid injection. We experienced two cases of acute respiratory distress syndrome with pulmonary hemorrhage induced by an illegal silicone fluid injection. The patients were 41 & 51 year old women, who complained of dyspnea. The chest X-ray and HRCT scan findings showed a bilateral ground glass attenuation on the bilateral dependent portion of the upper and middle lung zone. The patients clinical symptoms and the radiologic and other laboratory findings were compatible with acute respiratory distress syndrome induced by the silicon fluid injection. Here we report two cases of acute respiratory distress syndrome with pulmonary hemorrhage induced by an illegal silicone injection with a review of the relevant literature.

Pulmonary alveolar proteinosis(PAP) is a disorder in which an insoluble, proteinaceous material, rich in phospholipids, is deposited in the alveoli and bronchioles. The deficiency in the clearance and degradation of the intra-alveolar phospholipoproteinaceous material in PAP most likely represents a dysfunction of the type II pneumocytes. Although the pathogenesis and causative treatment of PAP is unclear a whole lung bronchopulmonary lavage is a relatively safe and effective treatment. Here we experienced a case of pulmonary alveolar proteinosis in a 62 year old female patient who had pulmonary tuberculosis approximately 20 years ago. She complained of aggravated dyspnea and chronic cough, and presented fine inspiratory crackles at both lung fields, diffuse ground glass opacity with some area of consolidation and smooth interlobular septal thickenings in both upper, right middled lobes, and a portion of right lower lobe. Optical microscopy of the lung tissue obtained by and open lung biopsy revealed many granulomas containing acid-fast smear positive bacilli and diffuse homogeneous PAS-positive fluid in the alveolar space. Immunohistochemical stain showed surfactant. A in the alveolar space. Antituberculosis drugs with bronchoalveolar lavage were used to treat the disease. Thereafter she showed improvement in her symptoms and a partial improvement in the chest X-ray and HRCT findings. We present a case of PAP associated with pulmonary tuberculosis.

A teratoma is the most common benign germ cell tumor that develops in the mediastinum. Patients with a mediastinal teratoma are usually asymptomatic. However, a spontaneous rupture of a mediastinal teratoma into the pleural cavity or adjacent organs can cause severe chest pain, hemoptysis, acute dyspnea, etc. Complications such as recurrent pneumonia, pericardial effusion, pleural effusion and great vessel invasion can sometimes occur. We encountered a case of a patient with an abrupt onset of dyspnea after persistent shoulder pain for one month. The X-ray examinations revealed a unilateral mediastinal mass with contralateral pleural effusion. Subsequent evaluations confirmed a spontaneous rupture of the teratoma into the contralateral pleural cavity.

Although reports of multiple primary malignant tumors have increased recently, cases of synchronous double primary tumors of lung and liver are rare. A 73-year-old man suffered from chronic cough. His chest x-ray showed segmental atelectasis of the right upper lobe. Bronchoscopy revealed a mass occluding the orifice of the anterior segmental bronchus of the right upper lobe, and a biopsy showed a squamous cell carcinoma. A synchronous hepatic mass was found by ultrasonography. However, F18-FDG-PET showed no evidence of a distant metastasis. The liver biopsy revealed a hepatocellular carcinoma. A right upper lobe lobectomy and a sleeve resection were performed for the lung cancer, and radiofrequency ablation was performed for the hepatocellular carcinoma.

Aneurysmal bone cyst(ABC) is a benign lesion and generally occurs in the long bones and vertebral column. ABC of the rib is an uncommon entity. We reported a case of ABC originating in the left first rib. The patient was a 19-year-old woman and presented with palpable mass on the shoulder. Chest X ray and MRI showed a large expansile mass, with multiple cystic areas, arising from the left first rib and bulging out into retroclavicular and paravertebral soft tissue, so the lesion was initially misdiagnosed as a soft tissue malignant tumor destructing adjacent rib. On histological examination, the mass, which was surrounded by a peripheral band of mature trabecular bone, consisted of multiple anastomosing cavernous blood channels separated by fibrous septa that containing osteoid, myxochondroid material and osteoclast-type giant cells.

Purpose : To compare perinatal characteristics, clinical courses, and overall morbidity between respiratory distress syndrome(RDS) with patent ductus arteriosus(PDA) and RDS without PDA in neonates. Methods : Eighty-three neonates who were diagnosed and treated for RDS in the neonatal intensive care unit(NICU) from Jan. 2000 to Dec. 2002 were included in this study. RDS was complicated with PDA(group A) in 17 patients and not complicated in 66(group B). PDA was diagnosed by echocardiogram in neonates with congestive heart failure symptom, cardiac murmur or chest X-ray findings of cardiomegaly or pulmonary edema. A retrospective study was undertaken of the perinatal characteristics and overall morbidity in group A and group B. Results : The birth weight and gestational periods of group A were less compared with group B. There was more perinatal asphyxia in group A. Incidence of overall morbidity such as bronchopulmonary dysplasia, intraventricular hemorrhage and death was higher in group A. Intravenous indomethacin was administered in 17 PDA infants. Conclusion : The perinatal characteristics in the two groups showed a significant difference. Incidence of overall morbidity in the two groups showed significant differences, however, there is no simple conclusion to draw because we didn't do multifactorial analyses to rule out other many risk factors affecting morbidity, such as gestational weeks or birth weight.

This study aims to find a way to control infection of community radiology effectively by calculating the degree of contamination, culture and identifying the flora in radiology of five general hospitals in Gyeongsangbuk-do. Staphylococcus, Micrococcus, Pseudomonas stutzeri, Pseudomonas oryzihabitans were identified as surface flora. These are know to be pathogens of hospital acquired infection and there was no radiology-specific flora. Research subject hospitals were conducting similar infection control education but degree of contamination of each hospital showed significant difference. Difference in degree of contamination according to contact sources were analyzed by Contact sources were classified into technologist-using, patients-using and common-using materials. Analysis of each hospital's degree of contamination showed that patient-using materials were significantly more contaminated than technologist-using and common-using materials (p<0.001). Devices which are similar to each other in monthly average frequency of use showed no significant difference in degree of contamination, but general X-ray devices and chest boards which are used most frequently showed higher degree of contamination than others. In addition, hospital A, B and C which have heavier monthly average caseload showed relatively high degree of contamination on irradiation devices which are used by technologists only or by technologists and patients commonly, office desks and doorpulls. Hence it is considered that intensity of infection control education should be different according to the degree of monthly average caseload. This study provided an opportunity to aware that technologists' feeling of contamination is crucial for infection control of radiology, and the Accupoint ATP public hygiene monitoring system which was used in this study for measuring the degree of contamination was proved to be an effective measuring device for hospital acquired infection management.
