Abstract
Orbital schwannomas are rare neoplasms of the orbit. The presenting symptoms are often
nonspecific. Classic imaging characteristics seen on magnetic resonance imaging (MRI)
and orbital ultrasound can be useful to help aid in the diagnosis of orbital schwannoma.
When diagnosed, the goal of treatment is complete surgical excision. The location
of the tumor within the orbit dictates which surgical approach would provide the best
exposure. When complete excision is achieved, recurrence rates are very low.
This article addresses the etiology, patient population, presentation, natural history,
and differential diagnosis of orbital schwannomas. Imaging characteristics and histopathologic
subtypes are reviewed. Treatment goals, approaches, and specialties involved in the
management of these patients is discussed. Finally, a representative case is presented.
