Understanding CT comments???

Hi,

I had a CT scan back in December due to chest pain. The results 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.

Scattered areas of interstitial change and atelectasis in the lung fields

Should I be concerned at all?
