Both imaging and image-directed biopsy play a major role in evaluating solitary pulmonary nodules. Imaging is used to determine whether the nodule is actually solitary or if multiple nodules are present. Once a nodule has been detected, imaging techniques can be used to characterize the nodule in terms of whether it is likely benign or malignant. As technology has improved, smaller nodules are ...

A solitary pulmonary nodule (SPN) is the most common radiographic presentation of lung cancer. The imaging characteristics of solitary pulmonary nodules are described and illustrated. The appearance and implications of extension of lung cancer to the pleura are explored. Finally, the contribution of various thoracic imaging modalities to the diagnosis and staging of lung cancer are discussed br...

The solitary pulmonary nodule is a common lesion that has multiple benign and malignant causes and when detected often creates a diagnostic challenge. Such a challenge is framed on one side by the need to detect and diagnose lung cancer or other malignancies at an early manageable stage and on the other side by the need to restrain from unnecessary intervention on benign lesions. The article wi...

It has long been recognized that tumors of capillary vessels in the lung are extremely rare. While pulmonary capillary hemangiomatosis, which is a rare cause of pulmonary hypertension, is relatively well known, there have been only a few reports of solitary capillary hemangioma (SCH) of the lung. Herein we report two cases of SCH. Both cases were first detected as a solitary nodule of the lung ...

background: serum lactate dehydrogenase (ldh) concentration is an indicator for tissue injury. it may be secreted locally in many conditions. for the first time, this study was performed to investigate the value of ldh level in bronchoalveolar lavage fluid (balf) in differentiation of benign from malignant single pulmonary nodules (spns) and to assess its relationship with serum ldh levels.   m...

solitary pulmonary nodule (spn) is a frequent finding on the chest x-ray and computed tomography. nuclear medicine techniques play an important role in the diagnosis and management of spn. in the current review, we briefly will explain the different nuclear medicine modalities in this regard including positron emission tomography (pet) using 18-f-fdg, and 11-c-methionine, and single photon emis...

which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. A 79-year-old woman presented with a pulmonary nodule, which was incidentally found during regular health examination. Chest computed tomography revealed a solitary nodule of 1.4 cm in diameter located in the upper lobe of the right lung (A). Percutaneous ne...

OBJECTIVE This study was designed to assess the ability of radiologists to accurately detect calcification within a solitary pulmonary nodule with chest radiography. MATERIALS AND METHODS Thirty-five solitary pulmonary nodules that were examined by both posteroanterior and lateral chest radiography and on thin-section CT were retrospectively identified. Fourteen radiologists blinded to the re...
