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 found in up to 0.2% of chest X-rays and around 1% of CT scans.[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 diagnosed this way.[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.
