The CT distinction between epidural and subdural hematomas is made in terms of shape. Epidural hematomas are more likely to be convex lenticular or fusiform high-density images. Subdural hematomas are more likely to be narrow, sickle-shaped or crescent-shaped dense images, which can be largely excluded. Sometimes both epidural and subdural hematomas are present at the same time, and then a high-level examination, including an examination of the head MRI, is required to further resolve and identify them. Then there is the identification of the clinical manifestations after imaging, which is also the corresponding identification point. Therefore, it is best to combine the patient’s clinical symptoms, CT examinations, and sometimes even MRI examinations together to best confirm the diagnosis.
