Methods: To summarize clinical experience of epidural hematoma and subdural hematoma of CT diagnosis in our hospital. Results: There were subdural hematoma in 12 cases, 9 cases showed the skull plate crescent or half moon shape under high density, 3 cases showed a wide range of double convex high density and all with midline shift, epidural hematoma 11 cases with the limitations of high density half-moon based. Conclusion: Epidural hematoma and subdural hematoma have their own imaging features, CT examination is a good means of diagnosis. ......
