Talc is a mineral widely used in the ceramic, paper, plastics, rubber, paint, and cosmetic industries. Four distinct forms of pulmonary disease caused by talc have been defined. Three of them (talcosilicosis, talcoasbestosis, and pure talcosis) are associated with aspiration and differ in the composition of the inhaled substance. The fourth form, a result(More)
OBJECTIVE The purpose of this study was to describe the high-resolution computed tomography (HRCT) features of fatal cases of Influenza A (H1N1) virus-associated pneumonia and to correlate them with pathologic findings. METHODS The study included six adult patients who died following Influenza A (H1N1) virus-associated pneumonia. All patients had(More)
OBJECTIVE The purpose of this study was to describe the high-resolution computed tomography (HRCT) features of pulmonary paracoccidioidomycosis and to correlate them with pathologic findings. METHODS The study included 23 adult patients with pulmonary paracoccidioidomycosis. All patients had undergone HRCT, and the images were retrospectively analyzed by(More)
Sir, We have read with great interest the case reported by Grunzke et al. [1] of an 11-year-old girl who presented with a history of cough, fever, and weight loss. Chest radiograph and chest CT revealed multiple cavitary lung lesions bilaterally, and PET-CT showed increased uptake in the lung lesions and regional lymph nodes. Lymph node biopsy confirmed(More)
Dengue hemorrhagic fever is an acute infectious disease caused by dengue virus. We described the high-resolution CT findings in a 70-year-old male with the disease, which was diagnosed by clinical examination and confirmed by serological methods. High-resolution CT demonstrated bilateral areas of consolidation with air bronchogram and ground glass(More)
OBJECTIVE To evaluate the high-resolution computed tomography (HRCT) findings in 53 patients with exogenous lipoid pneumonia and to compare the imaging features of adults and children. MATERIALS AND METHODS The study included 35 children and 18 adults. Statistical comparisons of findings in the 2 age groups were performed using either Pearson chi2 or(More)
We describe the case of a 32-year-old woman with pulmonary tuberculosis in whom a high-resolution CT scan demonstrated the reversed halo sign. The diagnosis of tuberculosis was made by lung biopsy and the detection of acid-fast bacilli in the sputum smear and culture. Follow-up assessment revealed a significant improvement in the lesions.
We read with great interest the well-written and informative pictorial essay by Park et al. (1), which reviews the thoracic manifestations of sarcoidosis, classifying them as typical and atypical. They indicate that the less frequent and unusual manifestations may be observed in 25% to 30% of cases, emphasizing the difficulty to differentiate sarcoidosis(More)
The authors describe a case of a 31-year-old female with tuberous sclerosis, a genetic, rare, variably expressed disease. Clinical symptoms were chest pain, and progressive dyspnea. Computed tomography scan of the chest showed bilateral, diffuse, small thin-walled cysts scattered throughout the lungs characteristic for pulmonary lymphangioleiomyomatosis.(More)
