Fungus ball of the maxillary sinus: clinical and diagnostic characteristics

“…Fungus ball (FB) of the paranasal sinuses (FBPS) is a distinct clinical entity, the most common form of non-invasive fungal rhinosinusitis, defined as an accumulation of dense fungal elements in the cavity of a single sinus, most commonly in the maxillary sinus. The disease is a localized manifestation, non-invasive, not at all or slightly aggressive, extramucosal, occurring especially in immunocompetent patients [1][2][3][4][5] .…”

“…According to recent data, FBPS is diagnosed in approximately 3.7% of all cases of CRS subjected to surgery [5][6][7] . The pathogenesis and risk factors for FBPS remain largely unknown, and the incidence of the disease has shown an important increase in recent years [1][2][3][4][5] .…”

“…Generally, the condition is unilateral, affecting only one sinus (up to 90-99% of cases) [1][2][3][4][5] . The most common location is the maxillary sinus (78-94%), followed by the sphenoid sinus (4-15%).…”

“…The most common location is the maxillary sinus (78-94%), followed by the sphenoid sinus (4-15%). Most often, the involvement of ethmoid sinuses (1-15%) is adjacent to the maxillary sinus, and the involvement of the frontal sinuses is much rarer (2%) [1][2][3]5 .…”

“…The treatment of fungus ball involving the paranasal sinuses allows a rhinosinusal endoscopic approach, with good results, low recurrence rates and disappearance of symptoms. Thus, the rapid and accurate diagnosis of FB is important to avoid unnecessary medical treatment [1][2][3]5 .…”
