Hello good day my husband and i had chest x ray and it says, for him persistent stable right upper lung fibrotic and nodular. Tb residuals noted..he did not even had a tb even when we got married 9 yrs ago, why is it so? And my result says, persistent outer left upper lung nodular focus and faint upper right lung fibrosis noted, tb residuals, what does it mean? I had my treatment for my last 2011 and completely finished the 6 months medication..thank you..your answer is a big help.
