From my ct scan "there was linear atelectasis in the lingular and both lower lobes." what does this mean and does this warrant any further tests or treatment? thank you?

Pulmonologist: You don't mention why you had the chest ct scan. Linear atelectasis indicates lack of full expansion with a deep breath in those areas of the lung. They may represent scarring from old bronchopneumonia and there may be no active lung problems at this time. I think it's a good idea to have an evaluation by a pulmonologist to determine whether any other testing,treatment or follow-up is advisable.
