Overview

Solitary pulmonary nodules are common.[1] The estimated prevalence of incidental solitary pulmonary nodule ranges between 0.09% to 7% in general population.[1] The incidence rate of solitary pulmonary nodule increases with age, tobacco use, and prior cancer; the median age at diagnosis is between 35 to 70 years. The prevalence of malignancy among solitary pulmonary nodules ranges between 0.2% to 50%. Males are more commonly affected with solitary pulmonary nodule than females. The male to female ratio is approximately 2 to 1. There is no racial predilection of solitary pulmonary nodule.[2]
