Spinal Cord Ser Cases. 2024 Dec 9;10(1):78. doi: 10.1038/s41394-024-00693-8.
Spontaneous spinal epidural hematoma (SSEH) is the rarest cause of spinal cord compression, causing paraparesis or quadriparesis. They account for less than 1% (0.1 patients per 100,000 patients per year) of all spinal canal space-occupying lesions, thus resulting in a paucity of literature. Here, we report three cases of SSEH; all had a neurological deficit on presentation and were surgically managed with decompressive laminectomy and evacuation of the hematoma.
Of the three patients, one had a history of coronary artery disease and was on anticoagulants. In the remaining two, no cause could be identified. The hematoma was located at the thoracic region in 2 patients and at the cervical in one. Hematoma were located dorsal to cord in 2 patients and ventral in one. Two cases presented within 30 h of the onset of symptoms with the ASIA (American Spinal Injury Association) impairment scale (AIS) A and B neurology. Both showed a complete recovery during their latest follow-up. However, one case presented after 2 days with AIS A neurology and improved to AIS B post-operatively at 30 months follow-up.
The myriad of symptoms and the need for an MRI for diagnosis have made SSEH difficult to diagnose clinically. Unlike other spinal pathologies where the severity of the preoperative neurological deficit is the best predictor of prognosis, in SSEH, time is the best predictor of prognosis. Our series highlights the fact that irrespective of the severity of the preoperative neurological deficit, timely diagnosis and early, adequate decompression surgery are essential for complete neurological recovery.
自发性脊髓硬膜外血肿(SSEH)是脊髓压迫最罕见的原因,可导致双下肢轻瘫或四肢瘫。它们在所有椎管占位性病变中所占比例不到1%(每年每10万名患者中有0.1例),因此相关文献较少。在此,我们报告3例SSEH病例;所有患者就诊时均有神经功能缺损,并接受了减压椎板切除术和血肿清除术。
3例患者中,1例有冠状动脉疾病史且正在接受抗凝治疗。其余2例未发现病因。2例患者血肿位于胸段,1例位于颈段。2例患者血肿位于脊髓背侧,1例位于腹侧。2例在症状出现后30小时内就诊,美国脊髓损伤协会(ASIA)损伤分级为A和B级神经功能障碍。二者在最近一次随访时均完全恢复。然而,1例在2天后就诊,ASIA损伤分级为A级神经功能障碍,术后30个月随访时改善为B级。
SSEH症状多样,且需要进行磁共振成像(MRI)来诊断,这使得其在临床上难以诊断。与其他脊髓疾病不同,术前神经功能缺损的严重程度是预后的最佳预测指标,而在SSEH中,时间是预后的最佳预测指标。我们的系列病例突出了这一事实,即无论术前神经功能缺损的严重程度如何,及时诊断以及早期、充分的减压手术对于神经功能的完全恢复至关重要。
