Fungal Sinusitis Presenting as an Ethmoid Mucocele

Fungal sinusitis was first reported in the late 1880s and was due to Aspergillus. Since this initial report, scattered case reports of fungal sinusitis have appeared in the medical literature, with the majority of these cases being due to Aspergillus and Mucormycosis. These case reports have also demonstrated multiple presentations of fungal sinusitis; however, our review of the literature did not demonstrate any previous case reports presenting as an ethmoid sinus mucocele. We now describe what we believe to be the first case of fungal sinusitis that presented as an ethmoid sinus mucocele.
