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.


Six infants under 1 year old in 4350 patients with intracranial aneurysms were retrospectively analyzed from January 2010 to December 2016.


The patients (5 females and 1 male) ranged in age from 2 to 11 (mean age, 4.67) months. Four patients presented with generalized seizure and vomiting, 3 showed lethargy, 1 presented eye deviation, and 1 had right-sided hemiparesis. Radiographically, two aneurysms were localized in the middle cerebral artery (MCA) of the M2 segment, two were located in the M3 segment of MCA, one was located at left MCA bifurcation, and one was located at the nonbranching site of the left supraclinoid internal carotid artery. All these lesions were successfully managed with aneurysm clipping or resection, and the improvement of neurological deficits was achieved in all patients.


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.
