Errors in the diagnosis of lung neoplasms

Abstract

Imaging diagnosis of lung cancer frequently occurs in the context of screening. In other cases, nodules may be detected on a routine CT scan or chest radiograph in asymptomatic patients. These tumors, which tend to be smaller at diagnosis, are referred to as central or peripheral as they have not spread beyond their local confines. While the features of the lesions’ borders can be suggestive of malignancy, they are not diagnostic. However, the presence of spiculation is thought to indicate a higher likelihood of malignancy [1] whereas clearly defined edges [2] may indicate an inflammatory process. Cavitation, frequently an indication of long-standing or advanced lung cancer, is most commonly seen in squamous cell lung cancer [3].
