In cases complicated by severe hemoptysis or other associated conditions such as pleural empyema or pneumothorax , surgery may be required to remove the aspergilloma and the surrounding lung tissue by doing ...
In humans, A. terreus is less commonly encountered as a pathogen than other Aspergillus species, most notably A. fumigatus, A. flavus and A. niger. [24] [26] Although less frequently seen in clinical samples, A. terreus displays evidence of amphotericin B resistance which correlates to a high rate of dissemination and an overall poor prognosis ...
