Spinal angiolipoma is a benign uncommon neoplasm composed of mature lipocytes admixed with abnormal blood vessels, and accounts for only 0.14-1.2% of all spinal tumors.
Retrospective data analysis.
We report two cases of a 64-year-old woman and a 65-year-old man with thoracic myelopathy due to spinal angiolipoma. Magnetic resonance imaging showed isointensity on T1-weighted imaging and hyperintensity on T2-weighted imaging and enhance with gadolinium administration. In one case, angiography elucidated the vascularity of the tumor and the relationship with concomitant hemangioma. Laminoplasty was performed to achieve tumor resection, and the postoperative course was uneventful with neurological improvement. Histopathological examination of the resected tumors revealed angiolipomas.
Although extremely rare, thoracic spinal epidural angiolipoma should be considered in the differential diagnosis of thoracic spinal lesions. Prognosis after surgical management of this lesion is favorable. Angiography was useful for preoperative evaluation of vascularity and the relationship with concomitant tumors.
脊髓血管脂肪瘤是一种由成熟脂肪细胞与异常血管混合组成的罕见良性肿瘤，仅占所有脊髓肿瘤的0.14%-1.2%。
回顾性数据分析。
我们报告了两例因脊髓血管脂肪瘤导致胸段脊髓病的病例，分别为一名64岁女性和一名65岁男性。磁共振成像显示在T1加权像上呈等信号，在T2加权像上呈高信号，注射钆剂后强化。在其中一例中，血管造影明确了肿瘤的血管情况以及与伴发血管瘤的关系。实施椎板成形术以切除肿瘤，术后过程顺利，神经功能得到改善。对切除肿瘤的组织病理学检查显示为血管脂肪瘤。
尽管极其罕见，但在胸段脊髓病变的鉴别诊断中应考虑胸段脊髓硬膜外血管脂肪瘤。该病变手术治疗后的预后良好。血管造影有助于术前评估血管情况以及与伴发肿瘤的关系。
