Intracranial arterial aneurysm complicating Behçet's disease

Area of Science:

• Vascular Medicine
• Rheumatology
• Neurology

Background:

• Behçet's disease is a rare multisystemic inflammatory disorder.
• Common complications include vascular lesions, particularly in large arteries.
• Cerebral artery aneurysms are exceptionally rare in Behçet's disease.

Observation:

• A patient with Behçet's disease developed a ruptured anterior communicating artery aneurysm.
• This occurred three years after the initial diagnosis of Behçet's disease.
• The rupture resulted in a secondary subarachnoid hemorrhage.

Findings:

• This case highlights a rare but severe neurological complication of Behçet's disease.
• Ruptured cerebral aneurysms are an infrequent manifestation, with only four prior reports.
• The anterior communicating artery was the site of the aneurysm rupture.

Implications:

• Increased awareness of cerebral artery aneurysms is crucial for managing Behçet's disease patients.
• Early detection and management of vascular complications may improve patient outcomes.
• This case underscores the importance of considering rare vascular events in Behçet's disease.
