Cavernous venous malformations, previously known as cavernous hemangioma are the most common vascular orbital lesion in adults.

The diagnosis of cavernous angioma has been presumed in this case because of its well-defined morphology, intraconal location, lack of involvement of optic nerve sheath complex and extraocular muscles, lack of symptoms and relative stability over 3 years. MRI correlation is helpful, and stable asymptomatic lesions can be safely monitored with imaging.
