Summary
Posterior fossa dural arteriovenous malformations (DAVMs) can cause papilledema. Treatment success varies, with embolization effective in one case, while another required a shunt due to sinus thrombosis.
Area of Science:
- Neurology
- Neurosurgery
- Radiology
Background:
- Posterior fossa dural arteriovenous malformations (DAVMs) are rare vascular lesions.
- Papilledema, or optic disc swelling, can be a symptom of increased intracranial pressure.
Observation:
- Two patients with posterior fossa DAVMs presenting with papilledema were analyzed.
- Both DAVMs exhibited venous drainage into the transverse, straight, and sigmoid dural venous sinuses.
Findings:
- The first patient's papilledema, linked to venous hypertension from drainage into a single transverse sinus, resolved after selective arterial embolization.
- The second patient developed venous sinus thrombosis, impeding drainage post-embolization, necessitating a lumboperitoneal shunt for intracranial pressure management.
Implications:
- Selective arterial embolization is a viable treatment for DAVM-induced papilledema when venous drainage is preserved.
- Venous sinus thrombosis is a potential complication that may require alternative management strategies, such as shunting, for elevated intracranial pressure.
