Pediatric posterior-circulation aneurysms are uncommon, difficult-to-treat lesions associated with significant morbidity and mortality. Infections and trauma are important risk factors in children. Here, we present a 10-year-old boy with a lower respiratory tract infection, rapidly progressive right-neck swelling, and weakness of the right upper limb. Imaging revealed a partially thrombosed right vertebral-artery pseudoaneurysm with multiple cavitory lung lesions. Subsequent laboratory work-up showed underlying primary immunodeficiency disorder (chronic granulomatous disease). The aneurysm was successfully managed by parent-artery occlusion. The child made a complete recovery without neurological sequelae.
