Solitary pulmonary nodule corresponds to a common radiographic finding, which is frequently detected incidentally. The investigation of this entity remains complex, since characteristics of benign and malignant processes overlap in the differential diagnosis. Currently, many strategies are available to evaluate solitary pulmonary nodules with the main objective of characterizing benign lesions ...

OBJECTIVES The solitary pulmonary nodule remains a common clinical problem. The essential question is whether the lesion is malignant or not. This discussion presents the clinical practice and looks at the problem. DESIGN Didactic. SETTING Academic tertiary-care hospital. PATIENTS Prospective thoracic database. INTERVENTIONS Minimally invasive technique. RESULTS The workup and treatme...

BACKGROUND The minimal invasive investigation of solitary pulmonary nodules becomes increasingly important with the emergence of lung cancer screening. OBJECTIVES We report the results of the first utilization of a recently developed procedure in a bronchoscopy suite, which approaches solitary pulmonary nodules via a transparenchymal path. METHODS This study was a prospective, single-arm in...

We give a complete relation between the singular values and eigenvalues of a complex skew symmetric matrix in terms of multiplicative majorization and double occurrences of singular values and eigenvalues. Similar studies are given for matrices in the algebras spn(C) and spn(R).

We report the case of a 63-year-old female patient who was evaluated due to a solitary pulmonary nodule. The final diagnosis was a solitary peripheral pulmonary artery saccular aneurysm. The patient was submitted to a pulmonary lobectomy with excellent recovery. Peripheral pulmonary artery aneurysms that arise from segmental or intrapulmonary branches are extremely rare, and their management is...

We report a case of Mycobacterium intracellulare (M. intracellulare) pulmonary infection with co-existing lung cancer and presenting as a solitary pulmonary nodule requiring differentiation from lung cancer. Computed tomography showed two nodules (20 mm) with spicula formation and pleural indentation on the right lower lobe of the lung (right S6 and S8). Transbronchial biopsies from the right S...

OBJECTIVE To compare the probability of cancer in a solitary pulmonary nodule using standard criteria with Bayesian analysis and result of 2-[F-18] fluoro-2-deoxy-D-glucose-positron emission tomographic (FDG-PET) scan. SETTING A university hospital and a teaching Veteran Affairs Medical Center. METHODS Retrospective analysis of 52 patients who had undergone both CT scan of the chest and a F...
