I had lung ctscan showing groundglass opacities n bilateral lower&right upper lobe representing cellular nonspecific interstitial pneumonia what is it?

Need evaluation. Ground glass opacity could represent simple pneumonia or serious lung problem. Better to consult a pulmonogist and may require lung biopsy if persist.
Can not say. Ground glass opacities on a ct scan can be many things. One of these is fluid in the lung or pulmonary edema, which is mostly seen if heart function is impaired. Alternatively this can represent inflammation involving the tiny air sacs called alveoli. This can have several causes including infection or other inflammatory lung disease. Discuss with your physician.
