目得：评价自发性脊髓硬膜外血肿（SSEH）患者的影像学表现和临床资料。材料和方法：13例（10例男性，年龄28-71岁; 3例女性，年龄40-65岁）SSEH从1986年至1995年进行了磁共振（MR）成像; 6例还进行了脊髓血管造影。轻微创伤、抗凝治疗、出血倾向增加或血管病变的患者包括在内。结果：发病率估计为每年每10万例患者中有0.1例。在MR图像上，血肿位于前（n = 8）或后（n = 4）硬膜外腔或两者（n = 1）。最常见的位置是上胸部区域。T1加权像是最有用的，因为病理信号从早期的等信号转变为中期的高信号。五名患者有轻微的创伤，四个正在接受抗凝治疗。结论：SSFH的发病率的粗略估计，结果证实了先前所描述的关联与轻微的创伤和抗凝治疗和低频率的动静脉畸形。
PURPOSE: To evaluate radiologic findings and clinical data in patients with spontaneous spinal epidural hematoma (SSEH).MATERIALS AND METHODS: Thirteen patients (10 men aged 28-71 years; three women aged 40-65 years) with SSEH from 1986 to 1995 underwent magnetic resonance (MR) imaging; six also underwent spinal angiography. Patients with minor trauma, anticoagulant therapy, increased bleeding tendency, or vascular lesions were included.RESULTS: The incidence was estimated to be 0.1 patients per 100,000 patients per year. On MR images, the hematoma was in the anterior (n = 8) or posterior (n = 4) epidural space or both (n = 1). The most common location was the upper thoracic region. T1-weighted images were most useful owing to the pathognomonic signal shift from isointensity with the cord in the early period to hyperintensity in the intermediate stage. Five patients had minor trauma, and four were receiving anticoagulant therapy.CONCLUSION: A rough estimation of the incidence of SSFH is provided, and the results confirm the previously described association with minor trauma and anticoagulant therapy and low frequency of arteriovenous malformations.
