Increased bronchovascular marki8ngs may be a sign of acute bronchitis
associated with respiratory infections. The hilar adenopathy needs to be investigated. A CT scan
of thorax should confirm the diagnosis. If the xray changes revert to normal after 2 to 3 weeks of antibiotic course then no need to worry. If there is no resolution then a CT scan of thorax and further evaluation with a pulmonologist is warranted. Some causes of hilar adenopathy are respiratory infections, tuberculosis
and sometimes malignancy.
