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

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