Mechanism of Injury In our series, most of the patients fell from less than 1 m, and even when they arrived in good neurologic condition, surgical EDH was found on CT. When mechanism of injury was a fall from more than 1 m, clinical presentation was much worse, with lateralizing signs, loss of consciousness, and a high rate of posterior fossa hematomas. This shows how vulnerable infants may be compared with older children even after minor head injury. A relatively high rate of posterior fossa EDH was found in our series compared with previous reports. [2-5,15]
