1Department of Ophthalmology, Loyola University Medical Center, Maywood, Illinois, USA.
Insights
A rare dural cavernous sinus fistula in a child was successfully treated with embolization. This case highlights a novel interventional radiology approach for pediatric vascular malformations.
Area of Science:
- Neurointerventional Radiology
- Pediatric Neurology
- Vascular Surgery
Background:
- Spontaneous dural cavernous sinus fistulas are rare vascular malformations.
- Cavernous sinus hemangiomas can mimic symptoms of dural fistulas, leading to diagnostic challenges.
Observation:
- A 9-year-old boy presented with proptosis and conjunctival congestion, initially misdiagnosed as a cavernous sinus hemangioma.
- Symptoms progressed to include pain, worsening proptosis, and decreased vision.
Findings:
- Emergent angiography confirmed a spontaneous dural cavernous sinus fistula.
- Successful endovascular embolization was performed to treat the fistula.
Implications:
- This case represents the first reported successful embolization of a dural cavernous sinus fistula in a noninfant child.
- Highlights the importance of considering dural fistulas in pediatric patients with unexplained orbital symptoms.
- Demonstrates the efficacy of interventional radiology in managing complex pediatric vascular lesions.
Abstract:
We describe the clinical course of a 9-year-old boy in whom a spontaneous dural cavernous sinus fistula developed. The patient initially presented with proptosis and conjunctival congestion believed to be caused by a cavernous sinus hemangioma and was prescribed oral prednisone. He subsequently developed pain, increased proptosis, and decreased vision. Emergent angiography revealed a dural cavernous sinus fistula, which was successfully embolized. This is the first case to our knowledge of a dural cavernous sinus fistula in a noninfant child that was treated successfully with embolization during angiography.
