Further workup included a CT scan of the neck which showed an exophytic enhancing soft tissue mass on the right posterior oropharyngeal wall, extending to the prevertebral space with abnormal marrow signal in the adjacent vertebral body and transverse processes of C2 and C3 vertebrae (Fig. 1).
Flexible nasoendoscopy images Left: Exophytic mass on posterior pharyngeal wall on flexible nasoendoscope. Right: Following surgical removal and long term antifungal treatment, the pharyngeal wall was flat with no observable lesion.

She responded to the anti-fungal treatment and at 16 weeks post treatment, the oropharyngeal mass was no longer visualized on nasoendoscope (Fig. 2).
Axial T1 weighted MRI scans of the patient's oropharynx over time. Left: MRI taken in October 2015 showing the exophytic mass. Middle: MRI taken in February 2016 post surgery. Right: MRI taken in May 2016 post antifungal treatment showing resolution of mass.

MRI scans at 6 months post treatment showed complete resolution of the mass and the absence of abnormal marrow signaling of C2 and C3 (Fig. 3).
