Imaging evaluation of 60 subjects
Out of 60 patients who underwent CEMRI, the most commonly involved sinus was maxillary sinus as observed in 90% of the cases. The MRI findings and structures involved are described in Table 1. Bilateral involvement was seen in 28 patients (46.7%). Out of total, 51 showed positive findings in the form of non-enhancement, thin enhancement, or heterogenous enhancement. Out of those 51, 49 were positive for KOH mount. Out of nine CEMRI with negative findings, seven were positive for KOH mount. The sensitivity and specificity of CEMRI as compared to KOH mount were 87.5% and 50% respectively. The positive predictive value, negative predictive value, and accuracy were 96.07%, 22.22%, and 85% respectively.
