Cavitary lesions in the lung are not an uncommon imaging encounter and carry a broad differential diagnosis that includes a wide range of pathological conditions from cancers, infections/inflammatory processes to traumatic and congenital lung abnormalities. In this review article, we describe a comprehensive approach for evaluation of cavitary lung lesions and discuss the differential diagnosis in the light of radiological findings.
