Fungal ball in the nasal cavity mimicking rhinolithiasis: a case report

Background: Fungus ball is an extramucosal fungal proliferation which completely fills one or more paranasal sinuses. Localization in the nasal cavity is extremely rare and can be confusing with rhinolithiasis. Case presentation: A 39-year-old female patient was referred to the ENT department for a left nasal obstruction that was associated with homolateral anterior rhinorrhoea. The diagnosis was an isolated fungal ball of the nasal cavity. Conclusions: The location of the fungus ball in the nasal cavity is rare and should prompt discussion of other calcified masses in the nasal cavity.
