All people are exposed to fungi as they are abundant in nature. The atmospheric air basically contains numerous fungal spores. Thus, pathological affection of the nose and paranasal sinuses is expected in case these spores find the suitable environment for their growth and tissue invasion.
Commonly sinonasal fungal infections are classified into invasive type and non-invasive type. The invasive type is characterized by growth of fungal hyphae invading the underlying structures; mucosa and submucosa, as well as bone and blood vessels of the infected sinuses, distinguishing it from non-invasive type.
Nowadays, early, and accurate diagnosis of fungal sinusitis is of extreme importance due to the increase in the number of COVID-19 associated invasive fungal sinusitis.
Aim of the study:
The aim of this study was to assess the role of MRI in the diagnosis of fungal sinusitis and its complications as well as emphasizing on the possible additive value of DWI and SWI in the radiological diagnosis of fungal sinusitis.
