Spontaneous Unilateral Subperiosteal Hematoma in the Orbit due to Self-Induced Asphyxia: Unusual Cause of Unilateral Exophthalmos

Abstract

Background: To report an unusual case of subperiosteal bleeding of nontraumatic etiology. Case Description: A 48-year-old female presented with an acute protrusion of the left eye after nonaccomplished suicide by means of asphyxia using a cable around the neck. At the time of presentation, the MRI showed an orbital subperiosteal hematoma causing an exophthalmos. After conservative treatment, there was a complete remission of the lesion. Conclusion: Nontraumatic subperiosteal bleedings without involvement of the intraocular structures and no vision-threatening intraorbital changes should be treated conservatively.
