Summary
Sudden vision loss in an elderly male was caused by a bleeding inflammatory pseudotumor forming a retrobulbar hematoma. Prompt surgical intervention improved visual function and extraocular movements.
Area of Science:
- Ophthalmology
- Neurology
- Pathology
Background:
- Orbital masses can present with diverse neuroophthalmological symptoms.
- Retrobulbar hematomas are a known cause of sudden visual impairment.
Observation:
- A 75-year-old male presented with acute retroorbital pain, visual loss, and ophthalmoplegia without trauma.
- Neuroimaging revealed a retrobulbar mass with a fluid component; biopsy showed a hematoma.
- Surgical exploration identified an inflammatory pseudotumor with hemorrhagic changes.
Findings:
- Histopathological diagnosis confirmed inflammatory pseudotumor with hemorrhage, not a vascular malformation.
- Subtotal resection of the pseudotumor and evacuation of the hematoma led to symptom improvement.
Implications:
- Inflammatory pseudotumors can hemorrhage, mimicking other orbital pathologies and causing visual loss.
- Early diagnosis and surgical management are crucial for preserving visual function in such cases.
