a

Median (range) for group data or value for individual data.

b

P value was determined by Wilcoxon signed-rank test.

c

CSF cryptococcal antigen titer determined by a lateral flow assay (IMMY, Oklahoma, USA). All six patients (case no. 1 to 6) had positive serum cryptococcal antigen results by the lateral flow assay.

d

This fungal sinusitis case was proven based on histology examination. The right mastoid excision tissue from the patient showed fungal hypha forms. However, culture was negative.

e

This patient had chronic sinusitis refractory to multiple courses of antibiotics empirically and was diagnosed clinically as having possible fungal sinusitis.

f

This patient tested positive for Histoplasma antigen in CSF.
