Fusiform basilar artery aneurysm in a child

Area of Science:

• Neurology
• Pediatric Neurology
• Vascular Neurology

Background:

• Giant basilar artery aneurysms are rare, particularly in pediatric populations.
• Progressive brainstem syndrome in children typically involves other etiologies.

Observation:

• An 11-year-old girl presented with chronic headaches and progressive brainstem signs, including choreiform movements.
• A ruptured giant fusiform basilar artery aneurysm was identified as the cause of her symptoms.
• No evidence of generalized arteriopathy was found in this patient.

Findings:

• Ruptured giant fusiform basilar artery aneurysm can cause pediatric progressive brainstem syndrome.
• The absence of generalized arteriopathy distinguishes this case from previously reported instances.

Implications:

• This case expands the differential diagnosis for progressive brainstem syndrome in children.
• Highlights the importance of considering vascular anomalies in pediatric neurological presentations.
• Underscores the need for early diagnosis and management of pediatric aneurysms.
