The solitary pulmonary nodule is one of the most common radiologic findings. The best approach to its management remains controversial. In this article, the role of computed tomography in the evaluation of the solitary pulmonary nodule is reviewed. The potential contributions of digital radiography and magnetic resonance imaging of the chest to the evaluation of the pulmonary nodule are also discussed.

ReviewRadiographic manifestations of primary bronchogenic carcinoma.
Carcinoma of the lung continues to account for more cancer-related deaths than any other neoplasm in the United States. The World Health Organization recognizes four main classifications of cell type. Squamous cell carcinoma is most often a central lesion that locally invades the hilus and mediastinum. ⋯ Small cell carcinoma is the most aggressive of the four cell types, having the worst prognosis. The classic presentation is the detection of hilar and mediastinal metastases while the primary tumor remains occult. Grossly enlarged hilar and mediastinal lymph nodes can be seen easily on chest radiograph and CT scan.
