CT FINDINGS IN PARANASAL ASPERGILLOSIS

Computed tomographic (CT) scan of eight cases of paranasal sinus aspergillosis were reviewed. Different CT patterns were observed such as areas of high densities, linear interlacing network of high density, radiolucent thin rim periphery to the masses, calcification, expansion of involved sinuses and bone erosion. Two cases of invasive type showed extension beyond the sinuses into the orbit and intracranially simulating a malignant tumour. The findings are similar to those described by previous authors. The differential diagnosis is also discussed.
