Aspergillus fumigatus lung abscess in two adolescents with cystic fibrosis.

Lung abscess is a severe but rare complication among non-transplanted cystic fibrosis (CF) patients. <10 cases have been reported in the international literature so far and bacteria were considered the responsible pathogen. We present two cases of CF adolescent patients who developed lung abscess from A. fumigatus, critically revealed with chest Computed Tomography. In one patient, a thyroid abscess was additionally detected. Both patients presented with fever, not responding to antibiotic therapy. Microbial cultures and molecular testing aided detection of the pathogen. Both patients responded well to antifungal treatment.
