A 23-year-old woman presented with right-sided nasal obstruction with sticky mucoid discharge for 3 years, associated with progressing right-sided proptosis since 1 year.

Nasendoscopy showed polypoid mass in the nasal cavity and middle meatus. Computed tomography (CT) scan revealed opacities in the right nasal cavity and all the ipsilateral sinuses, with multiple prominent radio-dense areas in the maxillary sinus and ethmoids (Figure 1).

The disease was extensive enough to push the lamina papyracea laterally and septum medially.

The nasal cavity and sinuses in the left were unremarkable. A clinico-radiologic diagnosis of fungal rhinosinusitis was made. Routine investigations revealed that the patient was nondiabetic, immunocompetent, and was otherwise healthy without any comorbidities.
