Pcrosonimr westermani is a lung fluke of humans that Is usually found in the lunes but may be fecund elsewhere in many unusual locations. A case of pelvic paragonimiasis was found incidentally by surgical intervention of inamatov disease and myoma uteri. She was a 51-year-old Korean woman complaining of lower abdominal pain and intermittent vaginal spotting. Numerous Porosonimus ova were observed in the reseated omentum in the pelvis after total abdominal hysterectomy. It is suggested that pelvic paragonimiasis may be one of causative agents of pelvic inflammatory disease.

Open lung biopsy was performed in thirty patients for the diagnosis and staging evaluation of interstitial lung disease during the period from January 1987 until December 1992. The age of the patients ranged from 14 to 71 years [mean 48 years], and the patients consisted of 14 males and 16 females. Preoperative FEV1`s were from 0.80 liter to 3.88 liters [mean 1.66]. Other non-invasive diagnostic studies such as PCNA, bronchoalveolar lavage, TBLB, and gallium scan were also done in addition to X-ray and high-resolution chest CT. Tweaty-eight were correctly diagnosed and 2 cases were not [diagnostic yield rate 93.3%]. Among the 28 cases,pathologic diagnosis influenced further treatment regimens and prognostic expectations in 23 cases [82.1%]. The diagnostic non-invasive studies other than open lung biopsy yielded a correct diagnosis without staging only in 5 cases. There was no mortality and only one complication, ARDS ; however, the patient recovered after 5 days ventilator support. Open lung biopsy, which is the gold standard for the diagnosis and staging evaluation of interstitial lung disease can be done safely and has value in clinical decision making. Also knowledge of the involvement of the lesion is important for proper selection of the biopsy site.

Good's syndrome (thymoma with immunodeficiency) is a rare cause of combined B and T cell immunodeficiency in adults. The clinical characteristics are increased susceptibility to bacterial infection and opportunistic viral and fungal infections. The most consistent immunological abnormalities are hypogammaglobulinemia and reduced or absent B cells. This syndrome should be treated by resecting the thymoma and replacing the immunoglobulin to maintain adequate IgG values. The author experienced one case of Good's Syndrome. The patient was a 64-year-old female who had a history of frequent sinopulmonary infection. Chest CT showed Pneumonia and anterior mediastinal mass and PCNB was taken and biopsy result was thymoma. She received thymectomy and replacement of immunoglobulin to control hypogammaglobulinemia.

Necrotizing bronchial aspergillosis usually occurs in the immumocompromised host. Aspergillus invades bronchial epithelium and forms endobronchial mass or endobronchial stenosis. A 78-year-old male patient with diabetus mellitus complaining of dyspnea and cough was admitted to our hospital. Plain chest X-ray and chest computed tomogram showed a large endobronchial mass and total collapse of left upper lobe of the lung. Bronchoscopic biopsy of the endobronchial mass revealed chronic inflammation. To confirm the endobronchial mass, we performed sleeve lobectomy of left upper lobe of the lung. Histologically the mass was diagnosed as necrotizing bronchial aspergillosis. We report a case of necrotizing bronchial aspergillosis in an elderly man who has diabetus mellitus with review of the literature.

A bronchus-associated lymphoid tissue(BALT) lymphoma of the lung is a rare disorder of patients with Sj$\ddot{o}$gren's syndrome. A 49-year-old woman was admitted for an evaluation of exertional dyspnea and general weakness which had persisted for two years. The patient had suffered from dry mouth and dry eyes for five years. The physical examinations showed a coarse breath sound with inspiratory crackles on the whole lung field, particularly on the both basal lungs. The laboratory data disclosed high titers of anti-nuclear antibodies, and anti-SSA (Ro), and anti-SSB (La) antibodies. Chest radiographs demonstrated the presence of bilateral, diffuse, reticulonodular densities in both lungs. Thin-section CT scans showed diffusely distributed mosaic pattern of an inhomogeneous attenuation extending over the entire lung zone. The histological findings from an open-lung biopsy specimen revealed an accumulation of lymphoid cells around the bronchioles and an extension of malignant lymphoma cells from the bronchiolar epithelium toward the alveolar space. Immunohistochemically, the neoplastic cells reacted positively to the CD 20 antigen and were focally positive for the UCHL 1 antigen. The histological diagnosis was consistent with a low grade marginal zone B-cell lymphoma originating in the BALT. Here, we present a case of a histologically proven BALT lymphoma of the lung in a patient with primary Sj$\ddot{o}$gren's Syndrome.

Lymphocytic interstitial pneumonia(LIP) is an uncommon condition in which the alveolar septa and extra-alveolar interstitial space are markedly expanded by small lymphocytes, plasma cells and histiocytes. Chest radiographs generally show nonspecific patterns with the most common pattern showing bibasilar reticular or reticulonodular infiltrates. Hilar or mediastinal lymphadenopathy and pleural effusions are usually absent. We encountered a 42-year-old female patient who was admitted to hospital because of exertional dyspnea and palpitation. The chest X-ray showed an enlarged bilateral hilar shadow and diffusely increased bronchovascular markings in both lung fields. The chest CT showed diffuse nodular infiltrations with mild septal thickening and combined patchy ground glass opacity in both lungs, and conglomerated mediastinal and bilateral hilar lymphadenopathy. A diagnosis of LIP was made from the tissue pathology taken by a thoracoscopic lung biopsy. The patient showed clinical and radiographic improvement after 3 months of treatment with prednisolone. We report a case of LIP presenting as diffuse nodular interstitial infiltrations with multiple mediastinal and bilateral hilar lymphadenopathy.

Purpose : To describe the MRI findings in the bronchial anthracofibrosis mimicking lung cancer on CT examination. Materials and methods : Ten patients, who showed CT findings mimicking lung cancer, were selected among fifty patients of bronchial anthracofibrosis proven by bronchoscopic biopsy, consisting of two men and eight women, ranging in age from 58 to 79 years old faverage age, 68 years old). CT scan and MRI were performed in all patients (n=10). Percutaneous lung biopsy on mass was performed in one patient. MRI findings were analyzed with the emphasis on the signal intensity of the mass (n=4), collapsed lung (n=4) and Iymph node (n=10) on axial T1 and T2-weighted images by two radiologists in consensus. No contrast enhancement was used in all cases. Results : CT scan revealed mass (n=4), atelectasis with obstructive pneumonia(n=4) and bronchial wall thickening(n=2). All patients showed enlarged medistinal Iymph nodes(n=10). The mass showed low signal intensity on T1WI and T2WI (n =4). The collapsed lung in patients with atelectasis indicated intermediate signal intensity on T1WI and low signal intensity on T2WI (n= 4). Nine patients showed low sisnal intensity of Iymph node on T1WI and T2WI, except one patient who showed central high signal intensity with peripheral rim of low signal intensity in right lower paratracheal llmph node on T2WI. Conclusion : Low signal intensity of a mass, collapsed lung, and lymph nodes on T2WI in anthracofibrosis patients may be helpful in differentiation of the lesion from lung cancer.

The primary lymphoma in the lung is very rare. Moot of the primary pulmonary lymphomas, which represent 3-4 % of extra-nodal lymphomas, are low-grade B-cell lymphoma. The low-grade B-cell lymphomas progress slowly and the prognosis of these are more favorable than that of the nodal lymphomas. However, high-grade forms progress rapidly with more severe course. The diagnosis of primary pulmonary lymphomas generally relies on the histopathologic findings of lung specimens obtained by surgical excision of the lesions or open-lung biopsy. Recently, less aggressive biopsies(transbronchial, transthoracic) and/or immunocyto-chemical, immunochemical and gene rearrangement studies on materials obtained by bronchoalveolar lavage have been used occasionally. The treatment of the primary pulmonary lymphomas has not been precisely codified. Several clinical data suggest that limited surgery or non-aggressive chemotherapy can provide long-term survival in patients with such slowly developing neoplasm, and demonstrated the need for the development of noninvasive diagnootic methods. In this study, we report a case of high-grade B-cell lymphoma of the lung which was treated with combination chemotherapy.

Diffuse pahbronchiolitis(DPB) is a relatively new, chronic, nonspecific, inflammatory disease of the lung that typically involves the airways in the "transitional" zone of the lung. Clinically, DPB strongly resembles chronic obstructive pulmonary disease (COPD) and the distinction between the two is crucial because the former is often fatal, requiring different therapeutic strategies. This study was prospectively carried out to assess diagnostic usefulness of radioaerosol scan(RAS) in DPB. RAS findings were analyzed with respect to the location and extent of abnormal aerosol deposition in the lung divided into the central, intermediary, and transitional airways and the peripheral airspaces. RAS showed mottled aerosol deposits characteristically in the transitional and intermediary airways with peripheral airspace defects. Such a deposition pattern contrasted sharply with central aerosol deposition of COPD. In conclusion, RAS appears to be a convenient, noninvasive, and useful diagnostic method of DPB.

Pulmonary veno-occlusive disease is a rare cause of pulmonary hypertension in which the primary abnormality is obliterative obstruction of pulmonary veins, especially venules. Clinicaly, we should suspect this disease in the case of congestive cardiac failure with pulmonary hypertension, chronic interstitial pulmonary edema, and normal or elevated wedge pressure on cardiac catheterization. We experience a case of pulmonary hypertension due to pulmonary veno-occlusive disease. A 55-years -old woman developed progressive dry cough and dyspnea for 3 months. Physical examination showed normal heart sounds, diffuse crackles in the whole lung fields. The liver was not palpable and pitting edema was absent. The diagnosis was made by chest HRCT, 2-D echocardiography, normal pulmonary capillary wedge pressure on cardiac catheterization, and confirmed by thoracoscopic lung biopsy. This patient was treated with vasodilator(calcium antagonist) and with mild symptomatic improvement. We reported a case of pulmonary veno-occlusive disease with review of literatures.
