A five years retrospective study of head trauma cases showing the rarity of multiple site extradural haematoma

Extradural haematomas constitute about 3% of all head injury cases and the frequency of extradural haematoma occurring at more than one site in a particular victim is even lower. During a five year retrospective study of extradural haemorrhage cases discovered at autopsy we found that multiple site extradural haematomas constituted 13% of all extradural haematomas observed. The incidence and the pattern of extradural haematoma and its association with fracture of the skull are given emphasis in this study.
