AbstractIntracranial cerebral artery dissection in children is very rare. We report 2 children who were diagnosed as having cerebral infarction which was suspected to be due to dissection of intracranial cerebral artery. Case 1: An 11-year-old girl presented with conscious disturbance and hemiparesis after seizure. Computed tomography (CT) showed cerebral infarction in the right frontal lobe. Her symptoms did not change, but angiography demonstrated reversible change. She received conservative therapy. Case 2: A 10-year-old boy complained of headache, and presented nausea and monoparesis of the left upper extremity. CT showed cerebral infarction in the right frontal lobe. He received superficial temporal artery-middle cerebral artery anastomosis because his symptoms fluctuated. In both cases, cerebral angiography showed string sign from the supraclinoid portion of the internal carotid artery to the middle and the anterior cerebral artery. Follow-up angiography showed improvement of stenosis. In pediatric cases of cerebral artery dissection, improvement with conservative therapy is frequently reported. It is necessary to follow-up such patients closely using magnetic resonance angiography or conventional angiography to determine whether or not surgery is indicated.
