Epidural hematomas are least likely in which age group?

Epidural hematomas are typically associated with a high-energy impact to the head, leading to a tear in the arteries in the epidural space, usually following a skull fracture. In children under 2 years, the anatomy and physiology of their skulls and brains differ significantly from older individuals. Their skulls are not as rigidly developed, and the brain is more cushioned within the skull due to the presence of a higher proportion of water and relatively softer brain tissue. This makes them less susceptible to injuries that would lead to epidural hematomas.

In contrast, children aged 8 to 14 have relatively more developed cranial structures that make them more prone to the types of injuries that can cause epidural hematomas. Similarly, elderly individuals often have a greater incidence of falls and associated head trauma, leading to a higher rate of epidural hematoma occurrences. Adults who are not elderly may also experience significant trauma that could result in an epidural hematoma, particularly in contexts such as sports or motor vehicle accidents.

Therefore, the age group of children less than 2 years is least likely to present with epidural hematomas due to their unique anatomical considerations and the nature of head injuries in that age group.
