Fibrotic Scanning seen and tiny calcification found during Chest X-Ray

I am 39 year old male, with no major health problem. I am married for past 9 years and have a healthy son, age 8 years. I am not overweight 80 kgs, Height 185 centimeters, my Blood Pressure is good 110/70, i have no cholestrol problem, but i have my SGPT/SGOT running on a slightly hiigher side (got to know of it since past 3 years), as during one sonography it was revealed that i have "moderate degree of diffuse fat infiltration" in my liver. I do not drink or smoke at all.

About 3 years ago, during a regular Chest X-Ray P.A., it was revealed- " Minimal fibrotic scarring is seen in right apex with tiny calcification in left upper zone". I have never got any tuberculosis or any other major disease, hence to rule out any possibility a C.T. Scan (COMPUTED TOMOGRAPHY) was carried out, in that the following was mentioned:

"Thin axial plain sections were obtained for both the lungs on high resolution algorithm.

A small sub centimeter sized rounded nodule with calcification is noted in the left upper lobe representing healed granuloma. Rest of the lung fields show no significant parenchymal or intersitial abnormality. No evidence of any fibrosis, honeycombing, air space consolidation and bronchiectasis is noted.

The trachea and main stem bronchi appears normal.

The pleural spaces appears normal.

No obvious mediastinal or hilar mass lesion is seen.

Impression- No active disease is noted."  

Recently for a Employment Visa (for Oman) medical test, during Chest X-Ray, " OLD CALCIFIED FOCI LEFT UPPER ZONE OF LUNG" has become a cause of rejection for me on medical grounds.

Could you please tell me if this is really serious, if so what extra test i need to undergo? Also is there any medication or minor surgical procedure to get rid of this calcification, as i understand that there was something at some time, but now there is no disease and it is only left there as a mark or remains.

Please reply!

Thanks.
