Recent CT report states:scattered reactive lymph nodes within the neck. Biapical pleural parenchymal fibrosis at the lung apices is noted. Please expl?

Nothing worrisome. Reactive lymph nodes are lymph nodes that are prominent but not worrisome, presumably secondary to a recent infection. Fibrosis is scarring. On it's own, not a terrible thing. Slightly unusual for a 37 yr old though. May be from an old infection. However, if you smoke, this would be secondary to damage.
