During an 8-year period, fifteen patients with subacute or chronic epidural haematoma were seen among 110 treated cases of extradural haematoma corresponding to a frequency of 13.6%. Increasing headache, nausea, vomiting, mild drowsiness and cranial nerve palsy were the symptoms resulting in the correct diagnosis in most cases. Clinical and pathological findings are described, and the factors influencing the course of events are discussed. The most important factors are cerebral atrophy, age, source of bleeding and location. By means of early CT (computed tomography) diagnosis of haematoma, fatal outcome could be prevented in most of the cases ¹⁾.

A 15-year-old boy who presented with a spontaneous epidural hematoma which was the result of a temporal eosinophilic granuloma. Multiple explanations for epidural hematoma in such cases have been discussed. Intratumoral hemorrhage followed by cyst formation and rupture may explain the pathophysiology of epidural hemorrhage formation ²⁾.
