Hepatic Calcification

What is the cause of Hepatic Calcification?
I have a solitary 15mm linear focus of calcification in Segment 8. This was found in Ultra Sonography.

What does this indicate?

PS: Due to the presence of this calcification, I have been rejected by the IAF.

The cause are peritoneal, ischemic, infectious, neoplastic, and idiopathic causes.  

Any past infections or parasitic infestation of the liver can cause them.  

Basically what it means is you have 1 calcification that is track-like or tubular in appearance measures 15mm in size and is seen in the upper portion of the right lobe of the liver.  They are generally benign but can also be seen in metastases.  They can indicate cirrhosis.  The linear form can also be linked with old TB and previous parasitic infestation.  

I'm sure IAF has something in their guild lines about it, but what I do not know.  I Hope This Helps.
