Traumatic intracranial cerebral artery dissection (ICAD) in the pediatric population is relatively rare. We report two traumatic ICAD cases in children. Case 1: A 13-year-old boy presented with headache and left hemiparesis after body contact while playing basketball. We found a cerebral infarction in the middle cerebral artery territory and dissection at the bifurcation of the right internal carotid artery and posterior communicating artery. Six days after onset, his right hemiparesis deteriorated, and the infarction progressed. Therefore, bypass surgery was performed. Three months later, he regained the ability to walk without a cane and resumed school. Case 2: A 10-year-old boy fell while skiing and experienced a severe headache several hours later. Neuroradiological examination revealed a subarachnoid hemorrhage in the basal cistern without aneurysm. Six days after admission, magnetic resonance angiography revealed stenotic changes and an irregularly shaped basilar artery (BA). On day 7, an angiogram confirmed BA dissection. The patient's headache gradually improved, and the irregular shape of the BA normalized 3 weeks later. He was discharged without any neurological deficits. Determining whether vascular reconstruction should be performed is challenging. However, we believe that therapeutic intervention should be performed promptly when symptoms or brain images deteriorate.
