Semiinvasive aspergillosis: a diagnosis to consider in a seemingly immunocompetent patient with a pulmonary nodule, haemoptysis and structural lung disease.

Semiinvasive pulmonary aspergillosis is an indolent form of pulmonary aspergillosis, which is seen mainly in patients who are mildly immunocompromised with underlying chronic lung diseases. This syndrome is rare, and the available literature is based on case reports and small case series. We describe here a patient with a semiinvasive aspergillosis associated with a probable idiopathic pulmonary fibrosis.
