AB  - <p>Onodi cells are anatomical variants of the posterior ethmoidal cells, which are greatly pneumatized laterally, and to some degree superiorly, to the sphenoid sinuses. Th e clinical importance of the Onodi cell is that it contains the optic canal and lies in close proximity to the optic nerve. Al-though the incidence of Onodi cell pa-thologies such as mucocele is extremely low, they may cause ophthalmological complications due to the close anatomical proximity between the Onodi cell and the optic nerve. Optic neuritis caused by as-pergillosis of the Onodi cell, presenting in the Emergency Department as an aspergil-loma within a pyomucocele, has not been reported previously. Here, we describe the fi rst such case; the aspergilloma within the pyomucocele was completely removed via surgical endoscopy.</p>
