DISCUSSION: Primary choice of treatment of aspergillosis is a protracted course of antifungals1. The duration of treatment is guided by the resolution of antigenemia, clinical and radiological findings1. For our patient, the endobronchial tumor-like lesions is caused by extensive pseudomembrane formation and polypoid granulation as a result of aspergillus pseudomembranous tracheobronchitis. The cavitatory lung lesion is a result of both primary infection and post-obstruction pneumonia. Treatment with voriconazole resulted in minimal radiological response. TBNA of the masses successfully relieved the obstruction of the right main bronchus, similar to incision and drainage of abscess, with marked radiological response. To our knowledge, there has been no report of TBNA drainage of endobronchial abscess to date, possibly due to the rarity of such lesions and advent of effective antibiotics. Drainage of endobronchial abscess allows for source control, relieves obstruction and prevents post-obstruction pneumonia. Risks involved includes spillage and tracking of pus into lower lobes, perforation and pneumothorax.
