As far as I know, ILD is somethings that can be seen definitively on CT or biopsy. It is also the most common (and serious) lung complication of Sjogren's. Since your CT and biopsy did not show it (and it would have if you had it), I'm thinking you don't have this complication...which of course I was thankful for.
