We have performed percutaneous intracavitary treatment with anti-fungal reagents in 8 patients with pulmonary aspergilloma (6 males and 2 female) over the past decade. Ages ranged from 43 to 84 years old. All of the patients had underlying lung diseases, seven having old pulmonary tuberculosis and one pneumoconiosis. Five patients had a history of hemoptysis or hemosputum. Amphotericin B (AMPH) was injected daily in 5 patients, Fulconazol (FCZ) in 2 patients, and both in the remaining patient. For AMPH, maximal dose, total dose, and treatment duration were 20 to 50 mg, 285 to 1560 mg, and one to 7.5 months, respectively, and for FCZ, 20 to 30 mg, 450 to 1600 mg, 3 weeks to 4 months, respectively. At the end of treatment, fungus balls disappeared in 2 patients, decreased in size in 3 patients and were unchanged in 3 patients. After follow up periods of 7 months through 6.5 years, 5 of 6 patients remained in roentogenologically better condition than before treatment, and 3 of 5 patients with episodes of hemoptysis or hemosputum have not since had airway bleeding. The prognosis of the other two patients are unknown, since they died of other diseases before this survey. One patient had aspergillus empyema 7 months after treatment. There were no serious side effects or complications directly related to treatment. It was suggested that continuous percutaneous intracavitary treatment with anti-fungal reagents is safe and effective for inoperable patients with aspergilloma.

Inhalation of dusts is an important cause of interstitial lung disease in the tropical countries such as India. While dusts of organic origin, such as the cotton dust causing byssinosis, generally cause bronchial or bronchiolar involvement and hypersensitivity pneumonitis, inorganic metallic dusts cause progressive pulmonary fibrosis. Silicosis, coal workers' pneumoconiosis, and asbestosis are the three most commonly recognized forms of pneumoconiotic pulmonary fibrosis. Pulmonary tuberculosis is an important complication seen in up to 50% of patients of silicosis in some reports from India. The presentation is generally chronic, although acute and accelerated forms of silicosis are known when the exposures are heavy. Breathlessness, dry cough, and general constitutional symptoms are commonly seen. Patients with silicotuberculosis or other forms of infection may also have significant expectoration, hemoptysis, fever, and rapid progression. Respiratory failure and chronic cor pulmonale occur in the later stages. The diagnosis is easily established if the occupational history is available. Dense nodular opacities on chest roentgenograms, which may be large in patients with massive pulmonary fibrosis, are characteristic. Emphysematous changes generally appear in advanced stages or in patients who smoke. Bronchoalveolar lavage and/or lung biopsy may occasionally be required to establish or exclude other causes of interstitial lung disease. Treatment is largely palliative, although a variety of drugs including corticosteroids and procedures such as whole lung lavage have been tried. None of these methods has yet been found successful in the treatment. Preventive safety steps, including removal of the patient from the site of exposure, are the only effective strategies to control disease progression.

A 76-year-old man, with a history of pneumoconiosis, developed massive hemoptysis after suction through endotracheal tube. Emergent bronchial artery angiography revealed that rupture of an aneurysm was the suspected culprit and coil embolization was performed. However, the bleeding persisted and he eventually succumbed. Here we bring forward the clinical evaluation and management of massive hemoptysis for discussion. It is note worthy that in patients with chronic inflammatory lung diseases, such as pneumoconiosis, massive hemoptysis may develop in the act of trachcobronchial toilet with suction.

Besides the risk of developing pneumoconiosis and chronic obstructive pulmonary disease, potential lung cancer risk may also increase due to exposure to silica and other carcinogens. Patients with hemoptysis symptom referred to our clinic depending on different forms of mass images in their thorax computerize tomography (CT) scan with the suspicion of coal-worker pneumoconiosis and lung cancer were hospitalized for investigation and treatment. The results of routine tests, sputum acid-fast bacilli and sputum cytology were evaluated as normal. PET/CT was ordered from patients for identifying malignancy. In PET/CTs of the patients, a pathological level of 18F fluorodeoxyglucose uptake was identified in different forms of mass images observed previously in thorax CTs. All the pathological specimens obtained by fiberoptic bronchoscopic biopsy and/or by mediastinoscopy were reported as benign. We aimed to present three pneumoconiosis patients with false positive PET/CT findings in the light of relevant literature. As a result, we thought that pneumoconiosis must be in mind also when considering about false positive results of PET/CT.

A wide spectrum of pulmonary complications occurs in patients with pneumoconiosis. Those complications include chronic obstructive pulmonary disease, hemoptysis, pneumothorax, pleural disease, tuberculosis, autoimmune disease, anthracofibrosis, chronic interstitial pneumonia, and malignancy. Generally, imaging workup starts with plain chest radiography. However, sometimes, plain radiography has limited role in the diagnosis of pulmonary complications of pneumoconiosis because of overlapping pneumoconiotic infiltration. Computed tomography (CT), ultrasonography (US), and magnetic resonance imaging (MRI) are potentially helpful for the detection of pulmonary complications in patients with pneumoconiosis. CT, with its excellent contrast resolution, is more sensitive and specific method than plain radiograph in the evaluation of pulmonary abnormalities. CT is useful in detecting lung parenchymal abnormalities caused by infection, anthracofibrosis, and chronic interstitial pneumonia. Also, CT is valuable in distinguishing localized pneumothorax from bullae and aiding the identification of multiloculated effusions. US can be used in detection of complicated pleural effusions and guidance of the thoracentesis procedure. MRI is useful for differentiating between progressive massive fibrosis and lung cancer. Radiologists need to be familiar with the radiologic and clinical manifestations of, as well as diagnostic approaches to, complications associated with pneumoconiosis. Knowledge of the various imaging features of pulmonary complications of pneumoconiosis can enhance early diagnosis and improve the chance to cure.

Detection of circulating anti-neutrophil cytoplasmic antibody (ANCA) provides a powerful clue in the diagnosis of vasculitis, but the clinical interpretation of the results is difficult in some cases. Here, we describe the case of a 65-year-old man who underwent hemodialysis due to focal segmental glomerulosclerosis and abruptly developed hemoptysis 14 years after a renal biopsy. At the time of the biopsy, computed tomography (CT) showed interstitial shadows in the lungs and pleural thickening, indicating pneumoconiosis that was accompanied by tuberculosis. Circulating myeloperoxidase-ANCA (10.5-32.5 U/ml) was subsequently noted, but the significance of this observation was unclear due to the preexisting disorders in the lungs and kidneys. Potent immunosuppressive therapies were avoided because of the pulmonary lesions and decreased renal function. There were few changes noted on follow-up CT, but infiltrative shadows emerged in the bilateral lungs, consistent with hemoptysis. The hemorrhagic shadows completely disappeared shortly after initiation of steroid therapy, with normalization of the serum ANCA level. Herein, we report this case, with an emphasis on the clinical dilemma faced in deciding the appropriate treatment. The findings in the case provide deep insights into clinical management of ANCA-positive patients.

The first case of pulmonary talcosis or talc pneumoconiosis related to inhalation of talc during its extraction and processing in mines was described by Thorel in 1896. Pulmonary talcosis is most commonly seen secondary to occupational exposure or intravenous (IV) drug abuse and, occasionally, in excessive use of cosmetic talc. Based on literature review, there has been an increase in reported incidents of pulmonary talcosis due to various forms of exposure to the mineral. We report an 82-year-old man who is diagnosed with Philadelphia chromosome positive pre-B cell acute lymphoblastic leukemia (ALL) treated with palliative imatinib who presented with chronic hemoptysis and dyspnea shortly after his diagnosis. His symptoms were initially thought to be due to an infectious etiology due to his malignancy, immunocompromised state, and radiographic findings until high-resolution computerized tomographic (HRCT) findings showed a diffuse pulmonary fibrosis picture that prompted further questioning and a more thorough history inquiry on his exposure to causative agents of interstitial lung disease. Very often, patients do not recognize their exposure, especially in those whose exposure is unrelated to their occupation. Our case emphasizes the need for thorough and careful history taking of occupational and nonoccupational exposure to known causative agents of interstitial lung disease.
