Intracranial pseudoaneurysms can cause severe epistaxis (nosebleeds). A rare case involved a young woman with a history of head trauma who presented with a pseudoaneurysm successfully treated with embolization.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Emergency Medicine
Background:
- Epistaxis is a common emergency department complaint, with most cases having benign causes.
- Less common causes include intracranial pseudoaneurysms, which can arise after head trauma.
Observation:
- A 24-year-old female with a history of traumatic brain injury presented with severe epistaxis.
- Imaging revealed a pseudoaneurysm of the internal carotid artery extending into the ethmoidal sinus.
Findings:
- The pseudoaneurysm was identified as the source of hemorrhage and successfully treated with ONYX embolization.
- Post-treatment imaging confirmed aneurysm occlusion and internal carotid artery patency.
Implications:
- Highlights the importance of considering intracranial vascular causes for epistaxis, particularly in trauma patients.
- Successful endovascular coiling offers a viable treatment option for these rare but critical conditions.
