Respiratory Failure With Aspergillus submaranianii and Lymphoplasmacystic Vasculitis

Aspergillus subramanianii is a very rare form of Aspergillus in section Circumdati. Aspergillus subramanianii has been rarely reported or ever published. IgG4 disease is an emerging disease entity that can be a diagnostic challenge. We report a critically ill patient who had invasive A subramanianii pulmonary aspergillosis and posthumous diagnosis of IgG subclass 4 interstitial lung disease.
