Abstract To investigate the clinical and imaging features of brainstem infarction with dizziness as the first symptom. Methods Eighty-seven brainstem infarction patients who had dizziness as the primary symptom in Department of Neurology in Beijing Friendship Hospital from March 2013 to August 2016 were recruited, and underwent MRI+DWI and CT angiography (CTA) examination. They were divided into three groups according to the distribution of affected lesions, the midbrain group, the pons group, and the medulla oblongata group, and their clinical characteristics were analyzed. Results Brainstem infarction with dizziness as the primary symptom mainly occurred in the pons, accounting for 68.97%, and the medulla oblongata accounted for 24.14% secondly. All patients were observed with dizzinessin, 18 cases (accounting for 20.69%) showed isolated dizziness(no other accompanying symptoms) among them, the most common associated symptom was unilateral limb weakness (accounting for 51.72%); the responsible vessel of midbrain infarction were mainly distributed in the posterior cerebral artery, and the pons were mainly distributed in the in basilar artery with mild-to-moderate narrow, the medulla oblongata were mainly distributed in the in vertebral artery with heavy-to-occlusive narrow. Conclusion Brainstem infarction with dizziness as the primary symptom mainly occurred in the pons. The most common associated symptom is unilateral limb weakness. Pathological vessels, the midbrain are mainly distributed in the posterior cerebral artery, and the pons mainly in basilar artery with mild-to-moderate narrow, the medulla oblongata mainly in vertebral artery with heavy-to-occlusive narrow.
