Huge cavernous hemangiomas enveloping the optic nerve successfully removed by a vertical lid split orbitotomy

Area of Science:

• Ophthalmology
• Neurosurgery
• Pathology

Background:

• Orbital masses can cause proptosis and vision impairment.
• Cavernous hemangiomas are benign vascular tumors that can occur in the orbit.

Purpose of the Study:

• To report a case of a large intraconal orbital cavernous hemangioma.
• To describe the successful surgical management and outcomes.

Main Methods:

• A 63-year-old woman with a 15-year history of proptosis underwent CT imaging.
• Complete tumor excision was performed using vertical lid split orbitotomy.
• Histopathologic examination confirmed cavernous hemangioma.

Main Results:

• CT revealed a large, enhancing intraconal orbital mass encasing the optic nerve.
• Surgical excision was successful with no intraoperative or postoperative complications.
• Histopathology confirmed cavernous hemangioma.

Conclusions:

• Cavernous hemangioma is a treatable cause of orbital proptosis.
• Orbitotomy provides effective surgical access for large intraconal tumors.
• Complete excision leads to satisfactory functional and cosmetic outcomes.
