Introduction: rhinosinusitis caused by the usual
Aspergillus spp. is very common. However, rare
isolates of Aspergillus causing fungal sinusitis
is also on the rise. case series: We hereby
report three cases of fungal sinusitis caused by
uncommon Aspergillus such as A. versicolor
and A. sydowii. case 1 was a 40-year-old female
came with complaints of nasal block and nasal
discharge for past one and a half years with
history of previous nasal surgery. Her computed
tomography (ct) scan of paranasal sinus (PNs)
showed bilateral ethmoidal sinusitis. case 2 was
a 43-year-old male known asthmatic presented with complaints of nasal block for last five
years, was diagnosed to have bilateral sinonasal
polyposis by anterior rhinoscopy. case 3 was a
17-year-old female known asthmatic presented
with headache, nasal discharge and frequent
sneezing for last six months. Her ct PNs showed
left side deviated nasal septum with left side pan
sinusitis along with right frontal sinusitis. All the
three patients underwent functional endoscopic
sinus surgery (FEss). the material was sent to
the microbiology laboratory for fungal culture
and potassium hydroxide mount. speciation
by slide culture was not conclusive. Hence,
molecular methods were opted for speciation.
conclusion: reporting of these cases will ensure
awareness among the microbiologists about the
not so common Aspergilli as a cause of fungal
sinusitis. the need of molecular methods for
speciation has also been emphasized here as it is
difficult to speciate these Aspergilli using routine
conventional methods. .
