What does ground glass in CT scan mean ?

default
Posted on Wed, 30 Jul 2014
Question: I had a chest cat scan due to a nodule being found for a cat scan looking for a kidney stone. The pulmonary dr I saw ordered the test today. I got the results and I have an apt with her in several weeks. However I am very scared after reading the results and would like for you to shed some light on the results if possible. Here they are:
Small 6 mm plural-based nodule in right middle lobe. Nonspecific 3 mm groundglass nodule density in the right costophrenic angle. Correlation with patients esophagus and followup is suggested warranted.

What does groundglass mean ?
Why correlation with espophagus?

Brief Answer:
Most probably these are benign lesions.

Detailed Answer:
Hello XXXXXXX
Thanks for writing to HCM

I have thoroughly gone through your findings in detail.

Your findings are incidental ones and findings are most probably due to benign reason.You shouldn't worry.
However it is necessary to go for follow up scan to detect any increase in size of nodules.

Nodules in your case may be the sequel of past infection.Infection heals by fibrosis,scar in natural course.However it may be due to variety of reasons like inflammation etc.

Ground-glass opacity is the term used in CT scan and it is nonspecific increased opacity of the lung.

It is not clear why it require correlation with espophagus.There may be some spelling mistake.Please check it from the reports and let me know.

Hello XXXXXX
Thanks for writing back

Majority of pulmonary nodules are sequel of infection.
Few cases may be related to pulmonary cancer and some cases may be due to esophageal cancer.
So,your doctor has rightly advised for follow up CT(it will exclude lung cancer)and oesophagoscopy will rule out any esophageal lesions.

Minimal linear atelectasis in lingular lobe and right middle lobe may be due to retained secretions or chronic infections.Minimal linear atelectasis can be ignored.
