Delayed recurrence of sinonasal rhinosporidiosis

Non-contrast CT scan of the paranasal sinuses demonstrated post-endoscopic sinus surgery changes and a 1.6x1.5x2.1cm soft tissue lesion located on the left lateral nasal wall anterior to the maxillary antrostomy site (Fig. 1). [...]the most accepted current classification is that R. seeberi is a eukaryotic pathogen in the Mesomycetozoea class [3].The mature phenotype of the organism includes a thick walled spherical structure termed sporangia containing smaller spherical structures termed sporangiospores. Patients with rhinosporidiosis involving the sinonasal cavities may present with non-specific symptoms including unilateral nasal bleeding, nasal obstruction, rhinorrhea, foreign body sensation, and postnasal drip.
