Abstract

Purpose: To report the clinical and radiological findings and management of a patient with intraorbital arteriovenous malformation (AVM) treated by transcatheter embolization of the feeding artery.

Case Report: A 15-year-old female patient was referred with a one year history of left eye proptosis without prior trauma. Orbital CT scan and MRI demonstrated a large intraconal mass lesion extending to the extraconal space in the inferior orbit; angiograms revealed an intraorbital AVM. Superselective catheterization of the feeding artery and embolization with absorbable gelatin particles (Gelfoam) and non-absorbable polyvinyl alcohol particles were performed in two separate sessions followed by surgical debulking. Signs and symptoms were diminished after 14 months.

Conclusion: Intraorbital AVMs can be treated by embolization of the feeding artery followed by surgical removal of the AVM nidus when the lesion is accessible.
