Bony orbital changes in allergic fungal sinusitis are reversible after treatment

ABSTRACT

Allergic fungal sinusitis (AFS) arises from a host hypersensitivity reaction to fungi residing within the sino-nasal tract. Computed tomography imaging may show heterogenous sinus opacification with bony erosion and expansion into the orbits. With advanced orbital involvement there is a risk of optic neuropathy and irreversible vision loss. We present a patient with AFS who presented with bilateral proptosis and early optic neuropathy. Radiologically, there was evidence of bony erosion and orbital wall compression. Following oral corticosteroids and full-house endoscopic sinus surgery, these changes reversed considerably. This case shows that bony and anatomical orbital changes from AFS are reversible with adequate surgical treatment.
