What is it about?

Intracranial aneurysms are extremely rare in infants, especially less than 1 year old. This study aimed to analyze the frequency of infantile intracranial aneurysm in our department and investigate the clinical characteristics, treatment strategies, and outcomes of this disease.

Why is it important?

Intracranial aneurysms should be considered in the differential diagnosis of infants who present with acute raised intracranial pressure. An improvement of neurological deficits is noted in infants who are managed promptly with microsurgical techniques of clipping during the long-term follow-up.


Infantile intracranial aneurysms are rare, and the exact cause is yet unknown. A sudden onset of lethargy and/or epilepsy, coupled with a bulging anterior fontanelle, could be considered to the differential diagnosis of a ruptured aneurysm. Currently, both microsurgical and endovascular treatments are valid approaches, although each poses specific challenges. In the case of infant patients with MCA aneurysms who have IPH, craniotomy that can both clip the aneurysm and remove the hematoma is recommended.
