Aspergilloma of paranasal sinuses - A common cause of unilateral proptosis in Sudan

The radiological appearances of six cases of primary fungal granuloma of the paranasal sinuses with involvement of the orbit are described. All were caused by Aspergillus flavus. Bone destruction is common and can be extensive, but is characteristically well defined, especially in the lateral wall of the antrum. The discrepancy between the gross radiological changes and the mild symptoms is a feature very suggestive of the condition. Associated displaced 'floating' teeth, expansion of ethmoids, and intracranial calcification are described and discussed. It is expected that, at least in certain localities where the incidence is significant, the radiologist would be able to help in recognising the earlier cases. © 1976 Longman.
