Objective:To study the CT diagnosis of chronic bilateral subdural hematoma.Methods:The CT features of 43 cases of chronic bilateral subdural hematoma were analysed rstropectively.Results:There were altogether 43 patients with 86 hamatomas. From them,42 hematomas revealed heterogeneous density,32 isodensity and 12 low density;66 hematomas were crescent shaped,15 were semi lunar shaped and 5 were 3 shaped. There was displacement of the borderline between grey and white matter toward the midline in 43 cases,narrowintg of the lateral ventricle in 41 cases and displacement of the midline structure in 17.Conclusion:Chronic bilateral subdural hematoma is encountered often in older males.
