Description: Thirty-one-year-old female with past medical history significant for a traumatic brain injury, von Willebrand disease, and migraines, that presented to an outside ophthalmologist with recurrent headaches and “sparkles within her vision.”. She was noted to have a normal exam, including dilated fundus exam, with one exception, mild disk edema of the left optic nerve. Humphrey visual fields were normal. The patient was referred for imaging due to a change in headaches and associated visual symptoms not typical of prior migraines. MRI of the orbits identified a well-circumscribed mass within the left orbit abutting the globe (Figure 1).
The patient was referred to the oculoplastics service at the Moran for further evaluation and treatment due to concern of optic nerve compression with edema on exam. She was found to 20/15 vision, pupils were equal and reactive without relative afferent defect, extraocular motility full, and color vision was normal OU. However, there was noticeable periorbital asymmetry with increased fullness of the left lateral orbit compared to right and left-sided proptosis of 1.5 mm.
Due to concern of optic nerve changes, the patient underwent an anterior orbitotomy with complete resection of the orbital mass without complications. Histopathological specimens were consistent with an orbital cavernous hemangioma with a pseudocapsule and large vascular spaces lined with endothelium (Figure 2). The patient made a quick and full recovery with a resolution of symptoms.

Summary of Case:
- Consider cavernous hemangiomas in both men and women with painless, unilateral proptosis in the 3rd to 5th decade of life.
- Use imaging to help aide in diagnosis as carvernous hemangiomas are well-circumscribed intraconal masses of which 90% can be diagnosed pre-operatively.
- Multiple emerging ways to access orbital tumors that decrease post-operative morbidity.
- Hormones (i.e. pregnancy and menopause) may influence size of lesion but no known factors predictive of growth.
- Presenting symptoms: Eyeball protrusion (90%), visual impairment (65%), double vision (20%), local Pain (18%), headache (12%), eyelid fullness/swelling (5%).
