Summary
A rare orbital hemangiopericytoma caused progressive proptosis and vision loss. Complete surgical removal led to restored vision and no recurrence during a 2-year follow-up.
Area of Science:
- Ophthalmology
- Neurosurgery
- Pathology
Background:
- Orbital tumors can cause significant visual impairment.
- Hemangiopericytoma is a rare vascular tumor that can occur in the orbit.
Observation:
- A 50-year-old male presented with a 10-year history of progressive right eye proptosis and decreased visual acuity.
- Orbital CT revealed a large, enhancing retrobulbar mass compressing the optic nerve.
Findings:
- Surgical excision via lateral orbitotomy successfully removed the tumor.
- Histopathology confirmed the diagnosis of hemangiopericytoma.
- Vision was restored after subsequent cataract surgery and intraocular lens implantation.
Implications:
- Complete surgical resection is crucial for preventing recurrence of orbital hemangiopericytoma.
- Early diagnosis and complete removal offer favorable visual outcomes.
- Orbital hemangiopericytoma requires careful monitoring due to its potential for malignant behavior.
