Spinal Epidural Lipomatosis (SEL) is believed to be a rare disorder. The incidence and prevalence of clinically symptomatic SEL in patients with spinal stenosis has never been reported in the literature. Our study aims to determine the prevalence, incidence, and associated risk factors of SEL in patients with the diagnosis of spinal stenosis.
This is a retrospective study. We reviewed the charts of 831 patients with the diagnosis of spinal stenosis over a 30 month period. All patients had spinal MRIs. Grading of SEL was performed using the Borré method.
52 patients (21 female and 31 male) had symptomatic moderate and severe SEL. We found a prevalence of 6.26% and an annual incidence of 2.5%. SEL was most commonly seen at L5-S1 level. 27% had received corticosteroids. All SEL patients were overweight and 79% were obese.
SEL is not uncommon in patients with spinal stenosis. SEL should be considered as a possible diagnosis in those with symptoms of spinal stenosis especially in those with associated risk factors.
脊髓硬膜外脂肪增多症（SEL）被认为是一种罕见的疾病。文献中从未报道过椎管狭窄患者中临床症状性SEL的发病率和患病率。我们的研究旨在确定诊断为椎管狭窄的患者中SEL的患病率、发病率及相关危险因素。
这是一项回顾性研究。我们回顾了831例在30个月期间被诊断为椎管狭窄患者的病历。所有患者均进行了脊柱MRI检查。使用博雷方法对SEL进行分级。
52例患者（21例女性和31例男性）有症状性中度和重度SEL。我们发现患病率为6.26%，年发病率为2.5%。SEL最常见于L5-S1水平。27%的患者接受过皮质类固醇治疗。所有SEL患者均超重，79%为肥胖。
SEL在椎管狭窄患者中并不少见。对于有椎管狭窄症状的患者，尤其是那些有相关危险因素的患者，应考虑将SEL作为一种可能的诊断。
