Abstract: Abjective　To analyze the imaging characteristics and factors influencing pontine infarction in patients with the complication of type 2 diabetes mellitus.Methods　A total of 86 patients diagnosed with acute pontine infarction by head MRI at the Department of Neurology of Zhongguancun Hospital of Beijing between March 2015 and March 2017 were included in the study.The patients were divided into a diabetes group（n=38） and a non-diabetes group（n=48） depending on the presence of type 2 diabetes.The imaging characteristics in the two groups were compared，and the influencing factors were analyzed.Results　The incidence of anterior-medial pontine infarction and of lesions extending from the deep pons to the ventral surface of the pons，as well as the incidence of basilar artery stenosis were all higher in the diabetes group than the non-diabetes group（P<0.05）.Multivariate Logistic regression showed that stroke history〔OR（95%CI）=7.139（2.069，24.641），P=0.002〕and basilar artery stenosis〔OR（95%CI）=5.730（1.017，32.289），P=0.048〕 were the risk factors for pontine infarction in the patients with diabetes.Conclusion　Pontine infarction in the patients with type 2 diabetes exhibited characteristic imaging changes.The incidence of anterior-medial pontine infarction and of lesions extending from the deep pons to the ventral surface of the pons and basilar artery stenosiswas higher in patients with type 2 diabetes.Stroke history and basilar artery stenosis were risk factors for pontine infarction in the patients with type 2 diabetes.
