Abstract

Spinal epidural angiolipomas (SEAL) are rare benign tumors composed of mature adipose tissue and abnormal blood vessels. SEALs account for 0.04–1.2% of all spinal tumors and 2–3% of spinal extradural lesions. They are usually found in the mid-thoracic dorsal extradural region. Here, we present the case of a 52-year-old female with a rare SEAL involving multiple thoracic levels. A 52-year-old female presented with mid-thoracic pain and paraparesis (motor strength 3/5 proximal/distal). Magnetic resonance imaging (MRI) documented a well-demarcated, homogeneous dorsal epidural mass extending from T7 to T10. She underwent a laminectomy for tumor resection and decompression. The tumor, measuring 6 × 2 × 0.5 cm, consisted of mature adipose tissue and abnormal blood vessels. Postoperatively, the patient’s motor deficit fully resolved within 6 months. SEAL is a rare extradural dorsal thoracic spine tumor that can be readily diagnosed with MRI. The gold standard of treatment is gross total resection through a laminectomy.
多层次胸椎硬膜外血管脂肪瘤
脊柱硬膜外血管脂肪瘤(SEAL)是一种罕见的良性肿瘤,由成熟的脂肪组织和异常血管组成。脊髓硬膜外血管脂肪瘤占所有脊髓肿瘤的 0.04-1.2%,占脊髓硬膜外病变的 2-3%。它们通常出现在中胸背侧硬膜外区域。在此,我们介绍了一例患有罕见SEAL的52岁女性病例,病变累及胸椎多个层面。一名52岁的女性因中胸部疼痛和偏瘫(运动力量3/5近端/远端)而就诊。磁共振成像(MRI)显示,她的背侧硬膜外肿块从T7延伸至T10,边界清晰,质地均匀。她接受了椎板切除术,进行了肿瘤切除和减压。肿瘤大小为 6 × 2 × 0.5 厘米,由成熟的脂肪组织和异常血管组成。术后,患者的运动障碍在 6 个月内完全恢复。SEAL 是一种罕见的硬膜外胸椎背侧肿瘤,可通过核磁共振轻松诊断。治疗的金标准是通过椎板切除术进行全切除。
