Pulmonary cavity is the result of necrosis of lung parenchyma with evacuation of the necrotic material via the tracheobronchial tree. A communication with the tracheobronchial tree permits air to enter the area of necrosis, so the radiologic result show the a lucent defect. The radiologic characteristics of the wall of a cavity are determined by the reaction of the lung parenchyma to the pathologic process. Therefore, the shadows of the chest films in cavitary lesion were variable in its nature. The author, in 42 cases which have a cavitary lesion in X-ray findings among 172 cases resected lung obtained in P.N.U.H. from 1979 to June, 1985, studied similarities and differences between the pathogenesis of these lesions and the radiologic findings. The author reviewed the 42 cavitary lesions and the following results were obtained. 1. The cavitary lesions were seen in 42 [24.4%] out of 172 cases of resected lung disease. 2. Histopathologically, pulmonary tuberculosis was 47.6% and primary lung cancer was 9.5%. 3. The most common site of the lesion was right upper lobe. 4. The most common size of the cavity was from 3 to 6 cm in diameter. 5. Lobectomy was the most common operated method.

Achromobacter xylosoxidans is a gram-negative bacterium that can oxidize xylose. It is commonly found in contaminated soil and water but does not normally infect immunocompetent humans. We report a case of a cavitary lung lesion associated with community-acquired A. xylosoxidans infection, which mimicked pulmonary tuberculosis or lung cancer in an immunocompetent man. The patient was hospitalized due to hemoptysis, and chest computed tomography (CT) revealed a cavitary lesion in the superior segment of the left lower lobe. We performed bronchoscopy and bronchial washing, and subsequent bacterial cultures excluded pulmonary tuberculosis and identified A. xylosoxidans. We performed antibiotic sensitivity testing and treated the patient with a 6-week course of amoxicillin/clavulanate. After 2 months, follow-up chest CT revealed complete resolution of the cavitary lesion.

Lung cancer is the most common fatal malignant lesion in both sexes. Detection of the solitary pulmonary nodule is important because surgical series up to a third of solitary pulmonary nodules are bronchogenic carcinoma. Bronchioloalveolar cell carcinoma is a rare primary lung cancer and surgery is treatment of choice in brochioloalveolar cell carcinoma. We experinced a case of bronchioloalveolar cell carcinoma in solitary pulmonary nodule with cavitary lesion in chest CT scan, which is an uncommon finding in brochioloalveolar cell carcinoma.

Behcet's disease is a systemic vasculitis of an unknown etiology involving the arteries and veins of all sizes. There are reports showing that a pulmonary artery aneurysm or thromboembolism and superior vena cava thrombosis are present in 5-10% of patients with Behcet's disease and that lung parenchymal lesions are mainly airway consolidations resulting from hemorrhage or infarction. We encountered a patient with increasing pulmonary cavitary changes and localized aspergilloma. The patient was a 43-year-old man diagnosed with Behcet's disease with a history of recurrent oro-genital ulceration and uveitis, and who was administered methotrexate, colchicines, prednisolone. During the follow up he developed progressive dyspnea upon exertion and finger clubbing. Therefore further evaluations were performed. Chest computed tomography showed more advanced consolidations and cavitations than the previous film with the previously known aspergilloma still observable. An open lung biopsy was carried out to determine the presence of malignant changes, which revealed nonspecific vasculitis. Azathioprine was added resultion in an improvement of symptoms.

Sarcoidosis is a chronic multisystemic disorder of unknown cause characterized by presence of noncaseating epithelioid granuloma in affected organ. It is relatively common in western countries, but it is uncommon in East Asia including Korea. The lung is most frequently affected organ. Usual radiologic manifestation of thoracic sarcoidosis are readily recognized, but there are extremely diverse manifestation. Sarcoidosis rarely causes large pulmonary nodules, and cavitation in such lesion is very rare. We experienced one case of Sarcoidosis with Cavitary nodule of the lung and report it with brief review of the literature.

On the study of surface activity in excized lung extracts of various pulmonary diseases, following facts were concluded. 1]The minimum surface tension measured in lung extracts of tuberculous tissue surrounding cavitary lesion was 26.3dyne/cm and its stability index was 0.53. 2]Macroscopically almost normal lung tissue at a distance of tuberculous lesion in same lobe revealed 21.3 dyne/cm of minimum surface tension in extracts and its stability index showed 0.66. This low surface activity may be due to the chronic pneumonitis microscopically. 3] In the atelectatic lung which had been collapsed by chronic empyema the extracts revealed much higher minimum surface tension in 27.3 dyne/cm and its stabillry index revealed the least value of 0.47 without correlation of duration of disease. This suggests that the longstanding collapsed lung may be soon collapsed even after mechanical full expansion because of lack of surfactant.

A traumatic pulmonary pseudocyst is a rare complication of blunt thoracic trauma. The clinical symptoms and signs are similar to other respiratory diseases, such as pulmonary tuberculosis. Therefore, a trauma history with the resulting radiologic and clinical findings is important for making a diagnosis. A 26-year-old male was admitted to our hospital due to cough for 3 days. The chest x-ray revealed diffuse infiltrations and a cavitary lesion at the left lung. His left chest had hit a tree as a result of motorcycle accident one day before admission. Initially, it was assumed that his symptoms and chest X-ray might be due to a tuberculosis infection. However, bronchoscopy revealed old blood clots at both lungs, particularly in the left lower lobe bronchus. A transbronchial lung biopsy showed alveolar hemorrhage. A traumatic pulmonary pseudocyst was diagnosed from his trauma history and these findings. Computed tomography of the chest performed 4 months later showed regression of the cavitary lesion.

The cellular change of the pulmonary tuberculous lesions may be divided into two groups,exudative and proliferative form by their course and fate. In the most cases, the patients usually have very much complex type of cellular changes. Therefore, the shadows of the chest films in pulmonary tuberculosis are also much variable in nature. And Daniel said that knowledge of the pathology of tuberculosis and an appreciation of the method of progression and healing are essential to proper interpretation of the films. Author, having reviewed 33 cases of resected tuberculous lung obtained in N.M.T.H. for one year from Oct. '75 to Sep. '76 by surgical managements, classified the Pathological findings such as: 1) caseation only, 2) tuberculoma, 3) atelectatic lung 4) cavitary lesion and 5) atelectasis with cavity, and examined the relationship between the roentgenological characteristics of the chest films and the pathological process of tuberculous lesions of the resected lungs, The result were obtained as follows. (1) Tuberculoma was commonly appeared in $S_2$ segment in right and $S_6$ segment in left. (2) Atelectasis and destroyed lung were more commonly appeared in left lung than right, and their containing rate of cavity was 82%. (3) Cavities were mostly appeared in $S_1$ and $S_2$ segments of both lung and the appearance-rate of cavity on $S_6$ segment was higher in left than right. And among the cavitary lesions of the resected lung, cavity was not seen in the preoperative chest films in 22%. (4) The configuration, thickness and sharpness of the walls of cavities, which revealed the cavitary shadows in the preoperative chest films, were mostly depended on the degree of increased collagenous fiber of the wall, existence of perifocalitis, and more or less of the caseous masses on the inner surface of the cavity wall.

A 46 years old male showed radiologically a single cavitary nodular lesion in right upper lung, which extended to the regional chest wall. This finding has to be made into differential diagnosis of numerous pulmonary diseases including infections such as mycobacterial, fungal or bacterial, granulomatous diseases, and neoplasms. For the definite diagnosis, fine needle aspiration biopsy guided by biplane fluoroscopy was performed. The aspirates contained several sulfur granules, in the center of which many gram positive, filamentous organisms were compactly intermingled. Such a findings was compatible with pulmonary actinomycosis. Now the lesions is cleared out by medical treatment with amoxicillin for 3 months.

The roentgenologic appearance of carcinoma of the lung may vary considerably from case to case. And when it forms cavitary lesion, it is frequently confused with benign lesions and treated conservatively. Twenty-seven patients with cavitary bronchogenic carcinoma were treated in our St. Marys Hospital during the period 1984-1989. There were 24 males and 3 females. They ranged in age from 43 to 76 years. Symptoms of cough, blood-streaked sputum or pleuritic chest pain were present in all patients one month to 6 months before hospital admission and 7 patients among them were delayed in recognition of the malignancy from z month to 3 months. Of 27 malignancies with cavity, 22[81.5 %] were squamous cell ca., 3[11.1%] were large cell ca., and 2[7.4%] were adenoca. And of 22 squamous cell carcinomas, 5 were well differentiated, 13 were moderately and 4 were poorly. All lobes except Rt. middle lobe were involved [RUL 2 cases, RLL 13 cases, LUL 3 cases and LLL 9 cases]. We explored 16 patients and performed 7 lobectomy, 4 bi-lobectomy, 2 pneumonectomy and 3 08zC. Post-operative follow-up examination of the resected 13 patients indicated one and two year survival rates of 69.1 %[9/13 cases] and 37.5%[3/8 cases] respectively, and now 6 survivors whose post-operative periods were from 4 months to 37 months.
