Overview

• The comet tail sign is a finding that can be seen on computed tomographic scans of the chest.
• It consists of a curvilinear opacity that extends from a subpleural "mass" toward the ipsilateral hilum.
• The comet tail sign is produced by the distortion of vessels and bronchi that lead to an adjacent area of round atelectasis, which is the mass. The bronchovascular bundles appear to be pulled into the mass and resemble a comet tail.
