  • 1Department of Otorhinolaryngology-Head and Neck Surgery, Seoul National University College of Medicine, Seoul, Korea


Fungal sinusitis is a sinus infection caused by fungal species, most of which are aspergillus species. They can be classified mainly into two groups, invasive fungal sinusitis and non-invasive fungal sinusitis. Invasive fungal sinusitis is characterized by fungi not confined to the paranasal sinuses or the nasal cavity but invading the adjacent tissue and bone. Chronic invasive fungal sinusitis is one type of invasive fungal sinusitis and is a relatively rare disease. It can invade the adjacent sinus bone and tissue for months to years, resulting in bony sclerotic change, formation of mass and bony destruction, which can be mistaken for pseudotumor or malignant tumor. In this report, we report a case of a patient with chronic invasive fungal sinusitis, which was mimicking sino-nasal malignancy.
