Understanding CT terminology

Hi 

I recently had a CT of my chest due to chest pain. The CT findings were as follows 

Soft tissue settings showed:

An inhomogeneous thyroid gland with areas of calcification identified.  

No significant axillary lymphadenopathy.

Multiple small mediastinal lymph nodes identified.

CT Impression 12/28/16

Scattered areas of interstitial change and atelectasis in the lung fields

Multiple peripheral bronchi show mild wall thickening. Abnormal thyroid gland which should be correlated clinically

I have had an ultrasound of the thyroid since the CT and have been referred to a surgeon but nothing was ever said about the CT findings of my chest. I don't really understand whythe radiologist meant by some of the comments. Any help appreciated!
