The mechanism of<unk>  depends on which form, such as: * Acute fulminant form – the fungus invades into vessels causing thrombosis, necrosis with minimum inflammation * Chronic invasive –<unk>  hyphae invades tissue leaving necrosis with minimal inflammation * Granulomatous form – invasive hyphae invades tissue with inflammation and non-caseating granuloma (with foreign bodies). * Saprophytic infection – growth of fungus seen on mucous crusts within sinus cavity. * Sinus<unk>  ball – sequestration of<unk>  hyphae as densely tangled, and has gritty matted appearance. * Eosinophil related Allergic<unk>  – though not completely understood, a possible mechanism sees the protein component of fungus elicits IgE mediated allergic mucosal inflammation.
