Hello,  i am 26 years old an recently had a chest ct with dye and it showed thymic tissue, and bibasilar atelectasis... what is this and is it normal?

Not normal: With all these abnormal findings, you need to consult a pulmonologist. The thymic tissue needs further elucidation . What is the reason for the CT chest scan to start with? Do you have myasthenia gravis or some immune defect ? Atelectasis can be explained as airways ending up in a blind alley where there is no longer air sacs to provide air exchange. ...Read more
