Spontaneous occlusion of a Large fusiform Basilar artery dissecting aneurysm in a child complicated with brainstem infarction: A case report

Basilar artery dissecting aneurysms, although very rare in children, may be associated with severe morbidity and mortality. The management of these vascular lesions depends on clinical presentation of patients. Large fusiform vertebro-basilar dissecting aneurysms are exceedingly rare and can exert mass effect on the brainstem and cerebellum. We herein report the neuroimaging findings, including MRI, MR angiography, diffusion-weighted imaging, and conventional angiography, in a four-year-old boy with a large fusiform basilar artery dissecting aneurysm complicated with brainstem infarction. The implications of neuroimaging findings on the decision to treat this patient are also discussed.
