Abstract

Computed tomography (CT) of the chest is one of the most important imaging modalities available to a pulmonologist. The advent of high-resolution CT of the chest has led to its increasing use. While chest radiographs are still useful as an initial test, their utility is limited in the diagnosis of lung diseases which depend on higher resolution images such as interstitial lung diseases and pulmonary vascular diseases. Several metaphorical chest CT signs have been described linking abnormal imaging patterns to lung diseases. Some of these are specific to a disease, while others help narrow the differential diagnosis. Recognizing these imaging patterns and CT signs are thus of vital importance. In the following article, the authors attempt to describe a comprehensive list of the commonly encountered metaphorical chest CT signs and their clinical relevance.
