A plane screw fixation is a nidus for Paecilomyces sinusitis in a patient with aspirin exacerbated respiratory disease

Titanium plane screw fixation of the frontal sinus is an approach used by otolaryngologists to obliterate this space in an attempt to reduce sinus infections. In this case, however, the titanium used became a nidus of infection which cultured the fungus Paecilomyces. The patient also had a hypersensitivity reaction to mold with positive skin tests and IgE, as well as eosinophilic esophagitis. Treatment entailed anti-fungals, anti-IgE, and fungal immunotherapy to multiple fungal antigens prevalent to the geographic region. The patient also had aspirin exacerbated respiratory disease which responded to aspirin desensitization. Her symptoms resolved after 3 months.
