BACKGROUND
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.
CASE DESCRIPTION
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.
CONCLUSION
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.
背景
脊髓硬膜外血管脂肪瘤（SEAL）是由成熟脂肪组织和异常血管组成的罕见良性肿瘤。SEAL占所有脊髓肿瘤的0.04 - 1.2%，占脊髓硬膜外病变的2 - 3%。它们通常位于胸段中背部硬膜外区域。在此，我们报告一例52岁女性患有累及多个胸段水平的罕见SEAL病例。
病例描述
一名52岁女性出现胸段中部疼痛和双下肢轻瘫（近端/远端肌力3/5）。磁共振成像（MRI）显示一个边界清晰、均匀的硬膜外肿块，从T7延伸至T10。她接受了椎板切除术以切除肿瘤并减压。肿瘤大小为6×2×0.5 cm，由成熟脂肪组织和异常血管组成。术后，患者的运动功能障碍在6个月内完全恢复。
结论
SEAL是一种罕见的胸段脊柱硬膜外背侧肿瘤，通过MRI可容易地诊断。治疗的金标准是通过椎板切除术进行全切除。
