Its not uncommon if you are stable, MAC isnt treated. I was dx 5 years ago and was stable. Then i got pneumonia, was on antibiotics for 10 days and had a CXR which looked good. I kept taking my temp which was low grade 99 but a concern. My pulmonologist wanted to do another CXR but i wanted chest ct which showed another area of congestion. I was admitted for 5 days of IV Zosyn. An infectious disease reviewed my xrays and told me i need MAC tx not antibiotics!
Why didnt radiology pick that up? I toold my doctor i only want chest CT which are more sensitive. I started on MAC tx a month ago
