BACKGROUND: This study retrospectively investigated the clinical significance of undiagnosed solitary lung nodules removed by surgical resection. PATIENTS AND METHODS: We retrospectively collected data on the age, smoking, cancer history, nodule size, location and spiculation of 241 patients who had nodules measuring 7 mm to 30 mm and a final diagnosis established by histopathology. We compared the final diagnosis of each patient with the probability of malignancy (POM) which was proposed by the American College of Chest Physicians (ACCP) guidelines...

The number of solitary pulmonary nodules (SPNs) detected each year is expected to increase dramatically with the implementation of lung cancer screening. Although some will have radiographic features highly specific for benignity, the rest are considered indeterminate and require further investigation. The management options include continued surveillance or immediate diagnostic sampling. The decision to proceed with immediate sampling is determined by nodule characteristics (i.e., density and size), and patient risk factors and preferences...

In this second part of a two-part series, we describe an algorithmic approach to the diagnosis of the solitary pulmonary nodule (SPN). An essential aspect of the evaluation of SPN is determining the pretest probability of malignancy, taking into account the significant medical history and social habits of the individual patient, as well as morphologic characteristics of the nodule. Because pretest probability plays an important role in determining the next step in the evaluation, we describe various methods the physician may use to make this determination...

The solitary pulmonary nodule (SPN) is frequently encountered on chest imaging and poses an important diagnostic challenge to clinicians. The differential diagnosis is broad, ranging from benign granulomata and infectious processes to malignancy. Important concepts in the evaluation of SPNs include the definition, morphologic characteristics via appropriate imaging modalities, and the calculation of pretest probability of malignancy. Morphologic differentiation of SPN into solid or subsolid types is important in the choice of follow-up and further management...
