Epidural haematomas are usually associated with preceding head trauma. The entity of non-traumatic spontaneous acute epidural haematoma is rare and most commonly occurs in the presence of infectious disease. It can also occur in the presence of coagulopathy, vascular malformations of the dura mater and haemorrhagic tumours. Sickle cell disease, systemic lupus erythematosus, open heart surgery and haemodialysis have also been implicated as causative factors. The authors report two cases of spontaneous epidural haematomas (one of unknown aetiology and one from a coagulation disorder) and discuss the aetiological agents involved in this rarely described condition.
硬膜外血肿通常与先前的头部创伤有关。非创伤性自发性急性硬膜外血肿较为罕见，最常见于存在感染性疾病的情况下。它也可发生于存在凝血功能障碍、硬脑膜血管畸形和出血性肿瘤时。镰状细胞病、系统性红斑狼疮、心脏直视手术和血液透析也被认为是致病因素。作者报告了两例自发性硬膜外血肿病例（一例病因不明，一例由凝血障碍引起），并讨论了这种罕见病症的致病因素。
