An extraconal orbital cavernous venous malformation: A case report

Year: 2026

Type: article

Abstract: Cavernous venous malformation, previously termed orbital cavernous hemangioma, and recently classified as a venous malformation in the International Society for the Study of Vascular Anomalies (ISSVA) classification, represents one of the most common benign tumors of the orbit. It's a slow-growing lesion with mainly venous flow. Clinically, this lesion typically presents with a gradual onset of symptoms such as proptosis, vision loss, or diplopia, or it may be clinically silent and discovered incidentally on imaging performed for another reason. The reported cases of this lesion are typically located in the intraconal space. We present here an unusual case of a 40-year-old male with an extraconal cavernous venous malformation.
