Ankylosing spondylitis is a chronic inflammatory multisystem disease that primarily affects the axial joints. Pleuropulmonary involvement is an uncommon extra-articular manifestation of ankylosing spondylitis. There is a wide spectrum of pulmonary parenchymal changes in ankylosing spondylitis, beginning in the early stages of the disease and increasing over time. The lesions are usually asymptomatic, and not visible on chest radiographs in early stages. We reported a case of advanced ankylosing spondylitis in a 56-year-old man with progressive pulmonary bullous fibrocystic changes on both upper lobes that were misdiagnosed as tuberculosis in the early stages of the disease.

Cystic lesions or progressive cystic changes in adenocarcinoma of the lung have rarely been reported. We report a case of lung adenocarcinoma that progressed from ground-glass opacities (GGOs) and consolidations or nodules to extensive cystic lesions during 12 months in a young adult patient. A 29-year-old male was initially diagnosed with primary lung adenocarcinoma by transbronchial lung biopsy of the right lower lobe and lung to lung metastasis in both lungs according to imaging findings. The initial chest computed tomography (CT) scans showed multifocal GGOs, consolidations, and nodules in both lungs. Despite treatment with palliative chemotherapy, the patient's follow-up CT scans showed multiple, cystic changes in both lungs and that the lesions had progressed more extensively. He died of hypoxic respiratory failure one year after his diagnosis.

Lymphangioleiomyomatosis(LAM) is a rare disease of unknown etiology that occurs mainly in woman in her reproductive age. We recently experienced two cases of bilateral diffuse cystic lesion of the lung on chest X-ray and HRCT. The first case, a 26-year-old female, who had been diagnosed with tuberous sclerosis by the presence of clinical manifestation such as mental retardation, bilateral renal angiomyolipoma, adenoma sebaceum and generalized seizure, was admitted due to a recently developed hemoptysis. Chest PA showed diffuse ground-glass opacity with radiolucent cystic lesions of various sizes on both lung fields. HRCT showed innumerable small cystic lesions with suspicious diffuse ground-glass opacity on both lung fields The second case, a 30-year-old fema1e was admitted due to dyspnea and spewing of blood-tinged sputum for 2 weeks, shortly after delivery. Chest PA showed diffuse reticular and ground-glass opacities on both lung field. HRCT showed multiple well-defined and relatively uniform size air cysts with a uniform wall thickness on entire both lung fields, with small amount of right pleural effusion. By thoracoscopic lung biopsy she was diagnosed with pulmonary lymphangioleiomyomatosis. We report these cases with a brief review of the literatures.

We report here an unusual case of pericardial tuberculoma that was misdiagnosed as thymic carcinoma on an imaging study. A 48-year-old woman was referred for evaluation of an anterior mediastinal mass. Computed tomography (CT) scans of the chest displayed cystic masses mimicking thymic carcinoma at the anterior mediastinum. Pericardiotomy and surgical drainage of the cystic masses were done, and pathologic examination of the excised pericardial specimen showed a chronic granulomatous inflammation with necrosis, compatible with tuberculosis. Acid-fast bacilli were also identified in the specimen. After treatment with anti-tuberculosis drugs and steroids, the patient showed clinical improvement. Although tuberculous pericarditis usually presents as pericardial effusion or constrictive pericarditis, it can also present as a pericardial mass mimicking thymic carcinoma on CT. Therefore, we suggest that tuberculous pericardial abscess should be included in the differential diagnosis of a mediastinal mass in Korea, with intermediate tuberculosis prevalence.

We report a very rare case of mediastinal tuberculosis in a 57-year old woman who presented with a large mediastinal cyst on chest radiography. She had a 10-year history of exertional dyspnea, but felt comfortable at a rest. A subsequent chest CT suggested a mediastinal cyst with mediastinal lymphadenopathy and communicating pericardial sac. She underwent a thoracotomy and excision of the mass, which was histologically revealed to be of tuberculous origin. Although rare, the apparent increase in the incidence of tuberculosis may result mediastinal cysts being diagnosed mediastinal tuberculosis. We also briefly review mediastinal lymphadenopathy due to tuberculosis.

The introduction of high-resolution CT (HRCT) in recent years has improved the ability of radiologists to detect and characterize the diffuse infiltrative lung disease (DILD). The detection and diagnosis of diffuse lung disease using HRCT are based on the recognition of specific abnormal findings. In this article, pattern recognition of HRCT findings is reviewed in the differential diagnosis of diffuse infiltrative lung disease. In general, HRCT findings of lung disease can be classified into four categories based on their appearances. These categories consist of (1) nodules and nodular opacities, (2) linear and reticular opacities, (3) increased lung opacity, and (4) decreased lung opacity, including cystic lesions.

Pulmonary lymphangioleiomyomatosis is a rare disease, prevalent in women of reproductive age, and characterized by proliferation of atypical smooth muscle in the lung. A 44-year-old women with pulmonary lymphangioleiomyomatosis was presented. Chest radiographs showed diffuse increased reticulonoular infiltrations on the almost entire lung and high resolution CT illustrated multiple, well defined cystic lesions which were distributed diffusely through the lung. Histologic confirmation of lymphangioleiomyomatosis was made upon open lung biopsy. Treatment with methylprogesterone was initated.

A 57-year-old male patient was admitted to our center because of a cystic mass on the lower portion of the right major fissure that was found incidentally by chest X-ray. He did not have a history of trauma or anticoagulant use. The lesion was removed by video-assisted thoracoscopic surgery. Pathological examination revealed an organizing pulmonary hematoma without any complications, and a follow-up chest X-ray after 1 year showed no recurrence.

Pulmonary sequestration is an uncommon comgenital disorder and any specific finding has not been reported in chest P-A for diagnosis. We experienced a case of pulmonary sequestraion with visible feeding vessel in chest PA which was well matched with aortic angiography. This finding may provide the clue for the diagnosis.

Bilateral interstitial infiltration in chest radiography, which may be fine granular, reticular or of ground glass opacity, is the typical radiographic findings of Pneumocystis jiroveci pneumonia. Recently, atypical radiographic features, including cystic lung disease, spontaneous pneumothorax or nodular opacity, have been reported intermittently in patients with P. jiroveci pneumonia. We report the case of a 29-year-old woman with a transplanted kidney whose simple chest radiography and HRCT scan showed numerous miliary nodules in both lungs, mimicking miliary tuberculosis (TB). Under the presumptive diagnosis of miliary TB, empirical anti-TB medication was started. However, Grocott methenamine silver nitrate staining of a transbronchial lung biopsy tissue revealed P. jiroveci infection without evidence of TB. These findings suggest that even in TB-endemic area other etiology such as P. jiroveci as well as M. tuberculosis should be considered as an etiology of miliary lung nodules in mmunocompromised patients.
