CT对于硬膜外与硬膜下血肿的鉴别诊断

The differential diagnosis of CT for the epidural hematoma and subdural hematoma

目的:探讨CT检查对硬膜外与硬膜下血肿的鉴别诊断意义。方法:总结本院对于硬膜外与硬膜下血肿CT检查诊断的临床经验。结果:硬膜下血肿12例,9例表现为颅骨内板下新月或半月形高密度影,3例表现为范围较广的双凸形高密度影,均存在中线移位;硬膜外血肿11例,以局限性半月形高密度影为主。结论:硬膜外血肿和硬膜下血肿各有其自身影像学特点,CT检查是对其进行良好鉴别诊断的手段之一。

Objective： To study the differential diagnosis of CT for the epidural hematoma and subdural hematoma. 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.
