Aspergillosis of the sphenoid sinus with the involvement of the clivus.

Fungal infections of the nose and paranasal sinuses are frequent in this part of the world. One aspect of the increased frequency is the improved clinical, radiological and pathological diagnostic methods that are now available. Aspergillus is the commonest infecting fungus of the nose and the paranasal sinus. It is mainly a saprophytic spore producing fungus and can cause invasive and non-invasive infections. The initial report of fungal paranasal infection largely dealt with immunocompromised individuals as distinct from the allergic fungal infection. Aspergillosis confined to the sphenoid sinus is uncommon with only 34 cases having been reported in the literature. These were mostly seen in immunosuppressed patients. Isolated sphenoid sinusitis is uncommon and that due to fungal infection is rare. We report the case of aspergillosis of the sphenoid siiius where disease had extended into the upper part of the clivus bone.
