A 63-year-old female presented with abnormal lung shadows but had, apart from this, few symptoms. Computed tomography (CT) revealed multiple nodules and blockage of the pulmonary artery. She was immediately diagnosed with pulmonary artery sarcoma based on a careful differential diagnosis and underwent surgery. Her tumor was pathologically diagnosed as leiomyosarcoma (i.e. intimal sarcoma). Pulm...

Pulmonary nodules are of high clinical importance, given they may prove to be an early manifestation of lung cancer. Pulmonary nodules are small, focal, radiographic opacities that may be solitary or multiple. A solitary pulmonary nodule is a single, small (<-30 mm in diameter) opacity. Larger opacities are called masses and are often malignant. As imaging techniques improve and more nodules ar...

We present a case of right lung adenosquamous cell carcinoma that had obstructed the main pulmonary artery and superior pulmonary vein, causing multiple pulmonary infarctions in the right upper and middle lobes. Multiple peripheral pulmonary nodules showed clinical features that are characteristic of pulmonary infarction: rapid appearance and gradual reduction in size, pleural-based parenchymal...

PURPOSE To evaluate prospectively the value of size, shape, margin and density in discriminating between benign and malignant CT screen detected solid non-calcified pulmonary nodules. MATERIAL AND METHODS This study was institutional review board approved. For this study 405 participants of the NELSON lung cancer screening trial with 469 indeterminate or potentially malignant solid pulmonary ...

Abstract The differential diagnosis of multiple pulmonary nodules is large and includes congenital and inherited disorders, malignancy, infectious etiologies, noninfectious granulomatous and inflammatory conditions, among many others. Diagnostic evaluation is aided by attention to extrapulmonary symptoms and features. We herein describe an unusual case of multiple pulmonary nodules attributed t...

A 28 year old man with no underlying disease developed a cavity and multiple nodules in the lung from which Corynebacterium equi was isolated. He experimented with organic solvents and microorganisms including Corynebacterium species for several years. Computed tomography of his pulmonary lesions revealed that these nodules were related to the bronchial tree. Histologically, the lesions were co...

UNLABELLED Small pulmonary nodules with little or no perceptible (18)F-FDG uptake are relatively common findings on combined PET/CT images of patients with nonthoracic malignancies. Interpreting such nodules is often a diagnostic challenge, and this study aimed to evaluate the clinical significance of the nodules. METHODS Patients with pulmonary nodules < or =1 cm in diameter showing no (18)F...

OBJECTIVE Respiratory infections constitute a major cause of morbidity and mortality in solid organ transplant recipients. The incidence of pulmonary tuberculosis is high among such patients. On imaging, tuberculosis has various presentations. Greater understanding of those presentations could reduce the impact of the disease by facilitating early diagnosis. Therefore, we attempted to describe ...

OBJECTIVE To describe our initial experience with CT-guided percutaneous barium marking for the localization of small pulmonary nodules prior to video-assisted thoracoscopic surgery (VATS). MATERIALS AND METHODS From October 2010 to April 2011, 10 consecutive patients (4 men and 6 women; mean age, 60 years) underwent CT-guided percutaneous barium marking for the localization of 10 small pulmo...
