Chronic epidural hematoma

Chronic epidural hematomas are rare and refer to those who have hematomas more than 2 to 3 weeks after injury. In general, more than 13 days after the injury, the onset of calcification in the hematoma can be used as a basis for the diagnosis of chronic hematoma. This disease is mostly young men, probably because the dura mater is not as tightly attached to the skull as women, children and the elderly, and it is easy to peel off. The predilection site is exactly the opposite of acute epidural hematoma, that is, there are more in the frontal, parietal, and occipital regions, but less in the temporal part. The reason is that most of the temporal hematomas are prone to cause cerebral hernia, so the course of the disease develops faster.
