We report a case of non-invasive sinusitis caused by Scopulariopsis brevicaulis in a 70-year-old immunocompetent patient who had an antibiotic-resistant suppurative tooth infection evolving for seven months. The sinus endoscopy highlighted a foreign body at the bottom of the sinus, which led to the hypothesis of fungal ball sinusitis. Culture of excised tissue was positive for S. brevicaulis.
