The radiologic evaluation of the solitary pulmonary nodule (SPN) is a common diagnostic dilemma. Although available clinical data and findings on conventional radiographs are important components in determining the imaging approach to the SPN, evaluation with CT often is necessary for detailed evaluation. This article reviews the radiologist's approach to the evaluation of the SPN, with a parti...

OBJECTIVE To evaluate nodule visibility, learning curves, and reading times for digital tomosynthesis (DT). MATERIALS AND METHODS We included 80 patients who underwent computed tomography (CT) and DT before pulmonary metastasectomy. One experienced chest radiologist annotated all visible nodules on thin-section CT scans using computer-aided detection software. Two radiologists used CT as the ...

The concepts of the modern computer-aided diagnosis (CAD), the methods of pulmonary nodules detection and facts derived from the available literature on the pulmonary nodule differential CAD topic are compiled in one source and described in some details. Several issues of the lung cancer epidemiology and an early diagnosis are discussed. The analysis of the performed research shows an evidence ...

Metastatic calcification has been associated with multiple-myeloma-induced hypercalcemia. Despite of a relatively high prevalence of metastatic pulmonary calcification in patients with multiple myeloma, only a few cases have been clinically and radiologically detected. A 45-year-old Hispanic male presented to the Emergency Department with complaint of worsening weakness and myalgia. Laboratory ...

pulmonary echinococcus granulosus is a parasitic infection found worldwide. patients usually present with cough and/or hemoptysis with pulmonary nodule (s). rarely do they enlarge to such sizes as to present with dyspnea. we report two cases with the largest hydatid cysts of the lung reported up to date: one measuring 24.5 x 19 cm and the other 19.5 x 16.5 cm. these cysts were removed intact wi...

Pulmonary metastases from thyroid carcinoma typically cause a micronodular or miliary pattern throughout both lungs. Metastasis consisting of a solitary pulmonary nodule measuring 20 mm in diameter is rare. Here we report a case of a 66-year-old woman without a history of papillary thyroid carcinoma who presented with a pulmonary nodule measuring 20 mm in diameter, found on chest computed tomog...

The patient is a 59-year-old formerly smoking male with a history of T2N0M0, stage I colon cancer. He underwent a left hemicolectomy five years prior to presentation and was referred for an enlarging 7 mm pulmonary nodule noted on surveillance imaging. His past medical history was significant for coronary artery disease and hypertension. Given the deep location of the pulmonary nodule and the p...

OBJECTIVE Our objective was to evaluate the performance of a computer-aided detection (CAD) system for pulmonary nodule detection using low-dose screening CT images. MATERIALS AND METHODS One hundred fifty consecutive low-dose screening CT examinations were independently evaluated by a radiologist and a CAD pulmonary nodule detection system (R2 Technology) designed to identify nodules larger ...

The unexpected finding of a pulmonary nodule in an asymptomatic patient is a common clinical event. This paper examines the case of a 64-year-old woman who was discovered to have a small pulmonary nodule on routine examination. Differential diagnosis, modes of examination, and pathological findings are examined.
