脊柱良性骨肿瘤和肿瘤样病变的CT、MRI诊断

摘要

Objective To evaluate the imaging appearance of spinal benign tumors and tumor-like lesions. Methods CT and MRI findings in 32 cases with spinal benign tumors and tumor-like lesions were retrospectively analyzed,the lesions included hemangioma(n=11),giant cell tumor(n=10),osteoid osteoma(n=2),eosinophilic granuloma(n=4),fibrous dysplasia of bone(n=3),intraosseous neurilemmoma(n=l),aneurysmal bone cyst(n=1),which were proven by surgery and needle biopsy.Results The location of spinal lesions were in cervical(n=3),thoracic (n=13),lumbar(n=11) and sacrum(n=5).Different spinal benign tumors and tumor-like lesions had those relative specific manifestations.Conclusion Combined CT with MRI,spinal benign tumors and tumor-like lesions can be correctly diagnosed in most instances.%目的 评价脊柱良性骨肿瘤及肿瘤样病变的CT、MRI表现特征.方法 回顾性分析32例脊柱良性肿瘤和肿瘤样病变的CT、MRI表现,包括血管瘤11例,骨巨细胞瘤10例(3例合并动脉瘤样骨囊肿),骨样骨瘤2例,嗜酸性肉芽肿4例,骨纤维异常增殖症3例,骨神经鞘瘤及动脉瘤样骨囊肿各1例,均经手术或穿刺病理证实.结果 发生于颈椎3例、胸椎13 例、腰椎11例、骶椎5例,不同良性肿瘤和肿瘤样病变的CT、MRI表现各异,具有相对特征性.结论 综合分析脊柱良性肿瘤及肿瘤样病变的CT、MRI表现特征,多数病变可以做出准确诊断.
