Abstract:

Objective To compare the incidence, amounts and distribution of cerebral microbleeds (CMBs) in cerebral hemorrhage patients and cerebral infarction patients. Methods Stroke patients with complete data from Department of Neurology of People Hospital of Beijing Daxing District from August 2017 to December 2018 were consecutively enrolled in this study. All subjects were divided into cerebral hemorrhage and cerebral infarction groups. The image data of MRI SWI of all the patients within two weeks of onset were collected, to analyze the incidence, amounts and distribution of CMBs of the two groups. Results A total of 234 patients were selected, including 79 cases of cerebral hemorrhage and 155 cases of cerebral infarction. 65 (82.3%) cerebral hemorrhage patients had CMBs, and 41/65 (51.9%) patients had the amount of CMBs >5; 73 (47.1%) cerebral infarction patients had CMBs, 21/73 (13.6%) patients had the amount of CMBs >5. and the difference between the two groups was statistically significant (P <0.001). In cerebral hemorrhage group, CMBs involved both lobes and deep brain tissue in 40 patients (50.6%); in cerebral infarction group, CMBs involved both lobes and deep brain tissue in 25 cases (16.1%), and the difference between the two groups was statistically significant (P <0.001). Conclusions The amount of CMBs >5 were more common in cerebral hemorrhage patients than in cerebral infarction patients. CMBs involving both cerebral lobe and deep brain tissue were also more common in cerebral hemorrhage patients than in cerebral infarction patients.
