What Does Upper Zone Patchy Koch's Infiltration Means?

'Upper zone patch Koch's infiltration' appears to relate to tuberculosis. 

Tuberculosis, or TB for short, is sometimes referred to as Koch's Disease in honor of Robert Koch, who first discovered the bacillus responsible for the disease in 1882. In those days, and for decades afterwards, TB was one of the leading causes of death in the developed world.

In medical terms, an 'infiltration' is something within a major organ that should not be there, and as TB is a pulmonary condition, this usually means the lungs. 'Upper zone' would suggest the part of the lung nearest the lung's apex. It could mean a hole, displaced bodily tissue or some form of growth.

The 'patchy' quality you ascribe to the lung is likely damage caused by either your current condition (perhaps fibroids or nodules) or a previous condition, and is healed scar tissue.

If you are concerned about TB, please contact a medical professional. You can learn more for now by watching this YouTube film about the treatment of TB:

For clarity about any matters on this, I would recommend speaking to your doctor.
