Rounded atelectasis The typical findings of rounded atelectasis on CT are pleural thickening, pleural-based mass and comet tail sign. The theory is that a local pleuritis causes the pleura to thicken and contract. The underlying lung shrinks and atelectasis develops in a round configuration. The distorted vessels appear to be pulled into the mass and resemble a comet tail (4). #Diagnosis #Radiology #RoundedAtelectasis #Findings #Rounded #Atelectasis #RadiologyAssistant
