Overview
Solitary pulmonary nodule (SPN) is defined as a relatively well defined round or oval pulmonary parenchymal lesion equal or smaller than 30 mm in diameter. Solitary pulmonary nodule is usually surrounded by pulmonary parenchyma and/or visceral pleura and is not associated with lymphadenopathy, atelectasis, or pneumonia. In the majority of the cases, solitary pulmonary nodule can be encountered as a incidental finding.[1][2] The nodule most commonly represents a benign tumor, such as a granuloma or hamartoma, but in around 20% of cases it represents a malignant cancer.[2] Approximately 10 to 20% of patients with lung cancer are initially diagnosed with solitary pulmonary nodule.[2] Thus, the possibility of cancer needs to be excluded through further radiological studies and interventions, possibly including surgical resection. The prognosis depends on the underlying condition.
Classification
According to the Fleischner society, solitary pulmonary nodules can be classified according to size, morphology, and/or distribution.

Epidemiology and Demographics
Screening
According to the the U.S. Preventive Service Task Force (USPSTF), there is insufficient evidence to recommend routine screening for solitary pulmonary nodule.[3]
