Solitary pulmonary nodule (SPN) is defined as a relatively well defined round or oval pulmonary parenchymal lesion equal to or smaller than 30 mm in diameter. It is surrounded by pulmonary parenchyma and/or visceral pleura and is not associated with lymphadenopathy, atelectasis, or pneumonia 9.
Questions to ask when you approach a solitary pulmonary nodule:
is the lesion solitary?
is it intrapulmonary?
is the lesion a nodule?
should be a discrete round/oval opacity 4-30 mm in diameter; a lesion >30 mm is defined as a mass, not a nodule
should not be linear or angular
There are many causes of solitary pulmonary nodule, including:
cutaneous lesion (e.g. wart, mole)
rib fracture or other bone lesion
