[|Human|] I had a pulmonary function test recently and part of the results said: ....there is a reticular infiltrate present in both lungs unchanged from the previous chest. I don t know what this means. Could you please explain in words that a sweet little old lady can understand?
[|AI|]  Thanks for your question on Chat Doctor. Reticular pattern on chest x-ray can be seen in1. Interstitial lung disease (OLD)2. Interstitial pneumonia (viral)3. Old healed scar etc. Since your reticular pattern on chest x-ray is static witChatDoctorparison in previous x-ray, no need to worry.  As this must be old healed scar lesion. As OLD and pneumonia will worsen if not treated. So static reticular pattern suggest healed lesion only.
