摘要：
累及孤立的腰椎的恶性周围神经鞘肿瘤极为罕见。一名72岁男性患者主诉腰肢痛2个月逐渐加重。CT扫描显示出孤立的椎体病变，高度支持转移性恶性肿瘤的诊断。18F-FDG PET/CT显示椎体病变具有异质性强烈的FDG摄取，SUVmax为16.4。病理检查确认了恶性周围神经鞘肿瘤的诊断。该病例强调了应考虑MPNST当椎体孤立侵袭时伴有增加的FDG摄取。版权所有，禁止转载。
Malignant peripheral nerve sheath tumor involving solitary lumbar vertebra is extremely rare. A 72-year-old man had a chief complaint of growing lumbocrural pain for 2 months. The CT scan detected a solitary vertebral lesion, which highly supported the diagnosis of metastatic malignancy. 18F-FDG PET/CT demonstrated that the vertebral lesion had heterogeneous intense FDG accumulation with an SUVmax of 16.4. The pathological examination confirmed the diagnosis of malignant peripheral nerve sheath tumor. This case highlights that MPNST should be considered when there is solitary vertebra invasion with increased FDG uptake.Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.
