Many cases of nontraumatic spinal epidural hematoma (SEH) have been reported, although the etiology of SEH remains unclear.
Our purpose was to report a rare case of nontraumatic acute SEH caused by extradural varices and to discuss the etiology of this entity.
STUDY DESIGN/SETTING: Case report.
A 27-year-old man.
Resolution of the patient's paraplegia, and pathological examination of the epidural vein of the patient and three other patients with cervical spondylosis.
Not applicable.
The patient recovered from paresis of both hands, although paraplegia remains complete. Pathological examination of the patient revealed abnormal veins that had thickened walls, varying caliber, and internal elastic lamina. In two of the three patients with cervical spondylosis, abnormally dilated veins resembling those in the SEH patient were observed.
We describe a rare case of SEH caused by extradural varices. It is speculated that spinal epidural veins can possibly develop an abnormal structure and fragility as seen in the present case and in spondylotic cases.
尽管脊髓硬膜外血肿（SEH）的病因仍不清楚，但已有许多非创伤性脊髓硬膜外血肿的病例报道。
我们的目的是报告一例由硬膜外静脉曲张引起的罕见非创伤性急性脊髓硬膜外血肿病例，并讨论该疾病的病因。
研究设计/地点：病例报告。
一名27岁男性。
患者截瘫症状的缓解情况，以及该患者和另外三名颈椎病患者的硬膜外静脉的病理检查。
不适用。
患者双手麻痹症状有所恢复，尽管截瘫仍完全存在。对该患者的病理检查显示静脉异常，其管壁增厚、管径不一且有内弹性膜。在三名颈椎病患者中的两名患者中，观察到了类似于脊髓硬膜外血肿患者的异常扩张静脉。
我们描述了一例由硬膜外静脉曲张引起的罕见脊髓硬膜外血肿病例。据推测，脊髓硬膜外静脉可能会出现如本病例及颈椎病病例中所见的异常结构和脆弱性。
