Abstract

Objectives: Clarify the difference between unilateral and bilateral chronic subdural hematomas related to historical factors, epidemiology, clinical manifestations, and imaging diagnosis. Methods and results: We conducted research on all patients with chronic subdural hematoma operated on at Military Hospital 103 and Central Military Hospital 108 during January 2022- January 2024. Among 146 patients, 47 cases (32.2%) had bilateral hematoma. Symptoms of hemiplegia and cognitive disorders in the unilateral hematoma group were 71.7% and 13.1%, significantly higher than the bilateral hematoma group at 53.2% and 2.1% (p =0.039 and p=0.037). On CT scan: Hematoma thickness and midline pressure in the unilateral group were higher than in the bilateral group (p=0.001 and p=0.000). In the unilateral chronic DMC hematoma group, the lesions mainly had reduced density (41.4%), while in the bilateral chronic DMC hematoma group, the lesions were mainly mixed density. Conclusion: Clinically, there are no differences in characteristics of age, sex, or underlying pathology between the one- and two-hemisphere damage groups; However, the unilateral hematoma group often shows signs of hemiplegia and cognitive disorders. Lesion characteristics on computed tomography (thickness, midline displacement, density) were different between these two groups.
